Mickey Moose,
I ran the main harness over the top of the engine when I did mine. It's butt ugly. Is there enough length in the Caddy harness to run the main harness down by the transaxle and then up to the firewall?

If you run your wires like mine (see picture) there is enough length - a couple need to be made longer. Bascially, I run them all along the fuel rail (tuck way down), the rear side runs along the intake manifold and under the distributor. The front rail wires join up here and straight into the cabin. Any wires running to the C500 are run along the firewall following the harness that is there already. C500 wiring run along the strut tower to the motor (or along the firewall). Big thing is to lose a majority of the wire loom as it is bulky, just tape it up.
Does that answer your question?

Yup, That's what I needed to know. Probably going to build a new harness the right way when I get all the rest of the little things sorted out.

...added:
Passkey description and diagram
AC wiring diagram
92-93 service manual
...to original post. I think that should be about everything now. Please let me know if I am missing anything.

That'd be me.  I found that especially the fuel injector wiring diagram was much better in the 92-93 diagram.

Mr Moose,
I have read that the 88 4 cyl throttle cable is a direct fit to the 4.9.throttle body arm. Is the 87 4cy throttle cable also a direct hook up? I think I have read that the 87-88 2.5's cables were the same.
Also would it be better for me to start with a 6cyl, or 4 cyl car for the basis of this swap? Better cooling maybe? Automatic or standard, I plan on using the 4T60E that was mated to a 4.9.
On the liter side:
I want to tell you how much I appreciate this write up you guys have done for us all. I cant give you another +. I have done lots of swaps in my life including a 2300cc Pinto engine into a VW van. The kit was called "The Pinto Bean". But this will be my first fuel injection implant.
In 1962 my first car was a 1955 Pontiac Chieftan. I swaped in a 1957 Cadillac V8 , found in the Dallas paper for $75.00. All of my friends at school called it the "Caddie-Pon". Looks like my last swap will be a Caddie-Pon also.

If they are the same part number I don't see why - but I can not comment if the 87 and 88 cables are the same since I never really looked into it. Maybe someone else can say they are.
Does not matter what car you start with - however you will need the rad from a V6 car - I would also go with an automatic car since you will be using the 4T60E just to make things a little simpler (no clutch pedal to deal with and it already comes with the automatic shifter/etc).
