Yeah I have to finish it first. I'll post them soon. The path is as stated. Taped and loomed like a stock 3800 in outward appearance - but follows the path as stated. Unless there is a reason not to, I have dropped the extra CTS connector, and the extra knock connector harness. (The engine harness runs directly to the CTS and directly to both knock sensors). Some stock 3800 harnesses have a small extra harness on the CTS sometimes and on the knock sensor. I have yet to find a reason to have that extra connection.
You can send me the Fiero harness and 3800 harness and then the price is just $400 shipped.

The extended harness on the trunk side knock sensor is needed when using the 65e. As there is not alot of room between the trans/motor. If not wired to use the extented harness then wire the plug long enough to make it easy to work with.
I just installed a harness made by the seller and can say it isba nice clean harness. There where a few snags but nothing major.

I hear you on the longer tails on the knock sensor. I was trying to keep things as neat as possible thus keeping the tails to the minimum. I plan on extending that one to make things easier. I'm torn as to include that connector or not. I can easily include it but I still don't see a function for it, and only see it as a potential problem. However if the consensus is to include the connector / sub harness I surely can.

Oh NOW you tell me! had to find that jewel by myself. my own harness at that!
Building another one. This one to be for an automatic and to include A/C, 3800 evap & cruise. Same pricing applies. Expected completion date is Saturday. Send me a pm if your interested. First person who actually puts the money down on it gets it.

Tested by observation IAC - Turn the key on, then off. The PCM resets the IAC by extending it and then retracting it to the correct position ICM - Rotate the engine and observe the Fuel Pump Relay, spark, noid lights Injectors
Tested by Fiero dash Temp Gauge Sender Oil Pressure Sender MAL light function Charge light function Reverse Switch Cooling Fan Relay wiring
Anyways - I have a just fininshed/ just tested harness on the engine right now. This harness is wired for a manual transmission, 3800-AC, SC-MAP EVAP, no EGR. It has long tails for the ICM, MAP and EVAP so you have flexibility to locate them. The harness isn't taped so it still can be customized.
First person who Paypal's me the money gets it. I am open to handling any donor harnesses in a 'core' fashion.
I can with the scanner see the TPS, CTS, IAT, MAP, HO2, VSS
The scanner will tell me an error if the EGR, or EVAP purge or EVAP vent systems are not present.
I have indicator lights in the dash to indicate REV Switch, Fuel Pump,
I can read the oil pressure sender and temp sender from gauges on the dash
After turning the key off I can see the IAC pintle reset. I can also watch the amperage on the power supply and verify the HO2 is heating.
I can crank the engine and tell that the fuel pump relay is activated again, and I can watch the noid lights on the injectors fire. I can also see the spark for each coil pack (Test wire to a gap to the other terminal.
Bump for a good harness...I installed one of the OP harnesses on an install I am wrapping up...Fired it up for the first time today and everything worked great with no issues...Good harness for a good price....Better get one while you can......
Lots of people who are interested, who are getting me donor harnesses, or who are just kicking tires. However right now, I don't have one that I am putting together for someone. So if there is someone who wants to get their name ahead of the others let me know.
$50 down payment gets it started. That or the donor harnesses. Final payment due when it is finished.
Now included at the same price - A long enough tail on the ODBII connector to locate it either in the stock position OR extend it up and mount it under the dash.
Just the thing for those of you who want to use a scanner more frequently.
I finally figured out what I need for my swap and filled out that spreadsheet you sent me. Hopefully that worked, and you're still making these~ I need the harness made to work with a 4T65E-HD trans.
Thx

A friend of mine is looking for you to make him a harness. He can't get on the forum right now but he wanted me to drop you his number. He can give you the specifics on series and year and stuff. I am just a middle man and posting for him. Contact Lee at (618) 304-4253
He works swing shift but you can call him whenever and leave a message and he will get back to you. Thanks
my own harness at that!
