AD, I checked the colors again and one is v/w the other solid v. Both of the these wires are heavy gage. The other wires are blk/rd and Gray/yel both medium gage. There is a fifth light gage Gray/yel with what looks like an in line fuse holder a few inches away. I did not find a fuse inside but it appears to be a bullet connector. I assume the lite wire goes on the same terminal as the other Gray yel.
I took photos but can't figure out how to attach an image. I could email it though.
The plug is square and the part that comes free routes down and out thru the firewall low right behind the accelerator pedal. let me know if you want to see the image.
