Anyone have wiring info for a 4cyl to V8 swap?

[1993SSP]

Here's my story. I have access to a lift rack, air tools and a garage, but I can only get it for a few days at a time. I have a 1986 mustang 4 cylinder 5 speed and I have a 1991 5.0 complete donor car. I kinda need the exact low down on the wiring if anyone has the info for me. I've got all the other stuff figured out except for the wiring. I will be having a friend help me with this project, we plan on doing the engine and harness on one weeekend and tackling the suspension and other stuff on another weekend

There is a complete tech note on 4 cylinder to V8 swaps at http://forums.stangnet.com/showthread.php?t=516785, It is in The "Useful Tech Thread Index" sticky at the top of the forum.

To start, I would completely strip the donor car. Set the parts aside.

Next, get the 86 on hoist and completely strip that. Then take your donor parts and assemble the 86 one step at a time. That's what I did on my swap, and it worked excellent and smooth.

I would drop the entire K-frame suspension, motor and transmission as one unit. Then just bolt it up into the 86. (The only thing you will have to change is the upper strut mounts.) The 84-89 Mustang have a different top plate with the back two studs next to each other. The 90-93 has the back to studs staggered. I ran into this putting 91 struts in my 81 notch.

I would also use the entire harness from the donor car to make it easy. Are you using the donor body parts and interior parts too?

Good idea, if you have a car lift anyway...same kinda thing they do with a gm F-body.

Yeah, he said he has access to a lift, so that is a plus. I would get up early and get done as fast as you can. Working without it will suck!!
