help with Coyote and "Painless" wiring harness

[Jrbrown_143]

Hello everyone,

I have now for the past month been working on the electrical portion of my MK4 Coyote build. I have the "Painless" chassis harness and so far have been perplexed by the whole thing and how it relates/connects to the Coyote harness.
Has anyone used this system for the Coyote? or be able to help me figure out how to wire things?
If anyone would be able to chat on the phone with me or something, that would help me out immensely!

Sorry Jon, this was put in moderation due to your post count and included link. I'm upgrading your status because you are an owner but the link thing will keep biting you until you reach 10 posts.

Here's a bump to the top.

Jon, not familiar with the Painless harness, but if you compare it to the Ron Francis harness wire labels, you may have some modicum of success. Just found out the 2 files I wanted to attach are too large; PM your e-mail address and I'll send them. You can correlate wires in your harness to those in the RF harness, one by one, and use the Coyote Fitment document to guide you through it. If this proves too difficult, you could sell the Painless and get the FFR RF harness.

Cheers, Dale

the more I think about it, and spoke with Painless today, I think I might just order the RF one from FFR.

An expensive option, unless they can break-out just the main harness for you; however, with the RF harness and the Coyote fitment instructions, it's fairly straight-forward. I had trouble understanding some of the instructions, but folks here bailed me out; so, if confused or unsure, just ask before you cut. Good luck.

A thought! Not sure what some have done with their RF harness when they decided to go the Infinity route. Put an ad for one in the Classified section of this and the other forum.

I've got the over the top OCD spreadsheet of every circuit, wire, wire color, connector pin number, terminal strip location, etc of how I wired my MKIV / Coyote / Ron Francis Harness / FFR Vintage Speedhut gauge setup if you go with the Ron Francis harness. Everything worked perfectly on the first attempt which even I was pleasantly surprised at...

X2 re Kevin's spreadsheet. It helped me over more than a few humps.

Thanks, FYI the only thing I have discovered after starting to drive it is that the Ron Francis harness lacks a bit in its grounding. I am in the process of adding frame grounds to the front and rear sub harnesses instead of just relying on the one out of the box ground lug near the fuse panel. My Fuel Gauge wanders a bit when more electrical items are running (like the cooling fan and headlights). It is grounded through the Ron Francis harness. Splicing into the ground wire on the front and rear harnesses for frame grounds should fix it giving the Ron Francis harness a total of 3 frame grounds.

Ended up getting the Ron Francis wiring and within a few hours had it all hooked up!

Good pointer Kevin, I might just do the same thing myself before final body fitting.

I welded 8 bolts (4 on 4" rails, and one at each of the 4 corners) for chassis ground locations.
