For those of you converting over to the 90mm Headlights that Fiero1fan is selling, Here is the schematic for the harnesses as well as some tips and notes on making them.
EDIT: Here is the information on which connectors to buy ~ The connectors are located here: http://www.rallylights.com/hella/Connectors.asp You need to buy 4 of the HL87193 (H9 connectors) and 2 of the CPH4CM (H4 male connectors)
High beam wires should be a minimum of 6" or longer than the low beam wires for proper distance between the lights.
Here is a close-up of the H4 male connector: (I used white wire instead of the red noted on schematic)
Here is what the H9 connectors look like:
The H9 connectors have the pins numbered. The blue clip needs to be pushed down AFTER the pins have been inserted. Note that the pins have a thin section in the middle, This needs to be vertically aligned so the blue clip can lock them in. Make sure the wire seals and the black cover are on the wires BEFORE inserting pins.
Here are some more pics:
H9 pin numbers (Notice the pin in position one is vertically in)
Blue clip "up"
Blue clip "down"
Pin with seal. (I personally crimp then solder the pins, This pics was taken of a harness someone else built and I reworked it for a member)
Connector before cover is clipped on.
You can sleeve them with the plastic 3/8" corrigated split sleeving and mark which connector is low and high beam.
Any questions just drop me a PM.

Will probably be a long time before/if I do this, but how about Xenon HID wiring?
IIRC, HID's don't like to be switched off and on quickly, so many cars leave the low beam HID's on all the time, even when running high beams. (please correct me if I'm wrong.) At least when using the High beam "flasher" the HID's don't turn off.

This is for the legal Hella HID 90mm capsules.
How would that be wired differently?
Actually some HID's like the Hella 90mm's don't really have a "high beam" lamp. There is a shield inside the bulb that blocks some of the light and the shield is raised up when "high beam" is activated. On our BMW the "high" beam lamp was not HID and was only for the "flash" feature. The HID lamp had the shield in it and raised for constant high beam.
Here is a quote from Rallylights website: The Bi-Xenon provides both high and Low beams in an HID Xenon lamp. This is accomplished by a shield which creates a Low Beam cutoff and retracts for High beam.
I do not know what is required to wire the HID. I haven't seen one in person. The H9 90mm lights actually do an excellent job of lighting up the road alot better than the H4 bulbs.

Oreif -- Thanks for posting the information on your adapter harness for the Hella 90mm modules. You've done it right, and I'm sure it will help a lot of people here. Just two things to add: 1) Depressing the blue tab on the H9 connectors is a more-or-less permanent final step. Don't do it until both terminals are inserted. 2) Don't test-install the outer housing before the blue tab is depressed. If you do, you will probably shear off the blue tab. (Been there, done that.)

See my earlier post here. All you need is to add one jumper to the Fiero headlight wiring to keep the HID low beams on when the high beams are selected. After startup, the HID headlights draw only about 35 watts each, which is actually less than the stock Fiero sealed beam headlights.

Clarification: The Hella 90mm HID modules with the same form factor as the halogen modules are not Bi-Xenon. They are low-beam-only assemblies just like the H9 halogen low beam version of the 90mm modules. The HID version of the low beam module is similar, but 3/4 inch longer at the rear:
Hella does indeed make 90mm Bi-Xenon headlight modules, but they are not mechanically interchangeable with the halogen modules. The Susquehanna Motor Sports web site doesn't make that clear:
Previously posted on PFF -- Beam pattern of the HID version of the 90mm low-beam-only module:
FWIW, the Hella 90mm HID low beam modules are 3/4 inch longer than the H9 halogen version,which is slightly too long to fit the Fiero without modifications (i.e. adding a bulge) to the headlight doors when using Timo's buckets.

1) Depressing the blue tab on the H9 connectors is a more-or-less permanent final step. Don't do it until both terminals are inserted.
Actually, it's not "permanent". You can pull them back up with a dental pick and tweezers. It's not hard to do. (One of the mistakes I made making the my original ones) But yes, It is better to make sure both pins are inserted first. Another thing is a small flat blade screw driver or dental pick works well for holding the blue lock up while you are inserting the pins. The blue lock can be accidently pushed down during insertion of the pins.

I edited the first post to include a link to Susquehanna Motor Sports web site connector page as well as the part numbers and quantities of the connectors required.
thanks for the info. what is the appropriate length for the low beam if you remember? i am guessing this is using 10 gauge wire thanks again, SHAwn
I made mine with 8" for the low beam wire length and 14" for the high beam wire length. This puts the H4 connection under the headlight housing so it looks stock. Also it allows some slack for when the lights move up and down they don't put tension/stress on the wires or connectors.
Yes I used 10 awg wire.
[This message has been edited by Oreif (edited 10-08-2008).]
The stock Fiero headlight wiring is the metric equivalent of 16 AWG, so anything 16 gauge or heavier (i.e. smaller gauge number) should be fine. FWIW, 10 AWG wire is approximately four times as big as (i.e. 4 times the area of) 16 AWG. The only significant disadvantage to using 10 gauge wire, though, is that it's a lot stiffer than the lighter gauges.

I thought that the 90mm Hella module is strictly low beam. For high beam another 90mm Hella module would be needed. (HID, or normal projector type) Personally I think HID for brights is overkill. HID lows are so great that the brights are only used as "flashers" for passing or to give signals to other drivers on the road.

The 90mm lamps that use the H9 bulb are two different lamps. Low beam has the projector style lens and the high beam has the clear lens. Both bulbs are the H9 65W but the projector lens focuses the beam so it is used as a low beam. http://www.rallylights.com/...ges/90mm%20Front.jpg
The stock dual filament headlamps are 35W for low beam and 55W for high beam.
There are 2 styles of HID. The 90mm that has the same case style as the non-HID (the HID high beam bulb has a "city light" bulb for the "flash" feature) and the bi-xenon which is low and high beam (the moveable shield)

So just to clarify. There is a HID 90mm low beam module, and then a HID 90mm high beam module. The high beam module contains a "city light", which IIRC is a off-center 5 watt bulb. Correct?
One more time ... Hella makes several 90mm headlight modules that will fit Timo's buckets; in the U.S. they are available from Susquehanna Motor Sports:
HL68139H -- D1S/D2S HID projector low beam (both DOT and ECE compliant, but will not fit the Fiero without modifications to the headlight doors)
PL 1BL 008 193-007 -- H7 halogen projector low beam (ECE compliant ... special order from SMS) PL 1KO 008 191-007 -- H7 halogen high beam with city light (ECE compliant ... special order from SMS)
To be street legal, headlights generally must comply with the following regulatory standards:
U.S. -- DOT Canada -- Either DOT or ECE Europe -- ECE
Reminder: It is not legal (at least in the U.S.) to install a HID capsule in a halogen housing. Changing the bulb style or wattage generally voids the regulatory compliance of any headlamp assembly.

Thanks.
How big is the modification to the headlight doors? Is it visible from the outside?

Major surgery is required, and yes, it will be visible. The 90mm HID modules are about 3/4 inch longer (all at the rear) than the H9 halogen version, so you have to create a bulge in each headlight door to clear the connector end of the D1S/D2S HID capsules. I don't yet know whether it's even possible, but I think it will be. How it will look is another matter. This experiment will be one of my winter projects.

Using DOT compliant parts doesn't guarantee that the finished installation is street legal but it's a far safer bet than using Driving/Fog lamps like some have done. Even if it's not technically legal, the proper installation of DOT compliant parts is less likely to blind the hell out of everyone in front of you.

bump for a great thread and a question. What if you want to run power directly from the battery (front mounted) to the lights? I'll be upgrading the lows to HID

ummmm relay? What relay? I didn't see anything about a relay. Sorry, probably a dumb question but i'm not the best at auto electrical stuff.
...edit to add i'm at work. might make more sense if i was looking at the car.
The relay in that application takes power from the battery and puts it too the headlights, only issue is how do you operate it from inside with the headlight switch. That's what a relay does. When you turn on the switch it tells the relay to open/close and then your line from the battery is feeding the headlights and not the switch.
They fit into these HL87123 Mini Relay Base that dovetail together. I have used the normally closed contacts to add a third relay for fog lamps with a high beam interconnect. (turns your fogs off when you bright up)
ummmm relay? What relay? I didn't see anything about a relay. Sorry, probably a dumb question but i'm not the best at auto electrical stuff.
Don't worry, this is DC. Just follow the path. Use your stock wiring to "signal" the relays to turn your lights on. Take the hot wire from your low beams and land it on pin85 on the first relay. Take the hot wire from your high beams and land it on pin85 on the second relay. Take pin86 (kinda looks like the number88 in the picture) to ground. Take a hot wire from the positive side of your battery through a fuse and land it on pin30. Run two interdependent feeders like this, one for high and the other for low. That way, should you ever blow one fuse, you will still have light. Pin 87 is your "normally open" contact. Take pin 87 on the first relay and take it to your lows. Pin87 on the second relay goes to your highs. Ground all bulbs at the bucket and you are done.
Here is where the fun begins. You can install a jumper with a diode between pin85 on both relays. This will give you full time low beams.
Yup, i know what a relay does, just thought i missed something in this thread (even read it again ) Thanks Hairballrm, that helps out alot! + for you. I'll probably want low on always with the HID's, so you just jump both 85's with a diode in the middle? What size diode do you use?
Current load on the solenoid side of the relay is 100-200ma. We use a generic in400x (in4004) diode purchased from radioshack.
a diode only allows current to flow in one direction. The diode jumper between the high and low beam signal wires allows current to keep flowing to the low beam relay even after you hit the bright switch on you column. There is a mark on it and it must be in the proper orientation. If you put it in backwards, your brights will stay on all the time and you lows will go out. Try explaining that one to Johnny Lawman
