Hello friends. As my title states, I discovered a problem in my RF Harness. I do not think the problem is systemic but you may want to check your harness during the wiring phase of your build.

I have been very methodical in my wiring. In lieu of just plug and go, I have been verifying continuity and schematics as I've installed the harness. I like to really know the e-system and understand all the circuits so if/when there is a problem, I understand how its all put together. In figuring out how I would wire in the sniper fan control, I discovered a LACK of continuity in the front harness to the fuse block. It was in 3 wires... fan control, horn and horn negative. I isolated the problem between the wire end terminations and the waterproof plug terminals. Pulled the pins from the plug, all looked good. The termination end of each wire had crimped spade connectors. Looking down the end of the spade connectors, I could see the bare wires crimped, so I was getting confused. Why would there be a line break in the harness? Didnt make sense.

I cut off the crimped spade connectors and checked continuity. Success.

The problem is in the picture. I had to carefully cut off the stiff plastic insulator around the spade connector but I found it.
An employee at the RF factory was apparently angry the day he/she built that section of the harness and went full-on gorilla beast mode when crimping the spade connectors.

This would've been a fun troubleshoot if I had it all built. I suggest you check continuity on all your harnesses just in case Arnold Schwarzenegger built yours too.

You should send this photo to RF

Opinion,
Since you are working with the current RF harness. how well is it set up, ease of installation? I have the original Painless harness and am considering purchasing the newer harness to simplify my installation.

Advice appreciated

I had nothing but good to say about The Ron Francis harness. It seems like the best of all worlds considering it is wired for, Mustang Donor, FFR, and Vintage gauges. I did not use and donor parts and used the Vintage gauges and when it was all plugged in everything worked. That's all I was looking for. I liked the fact that every wire has the name of what it goes to.

That is what I was looking to find out ggunter. Guess I am making the call unless somebody has a better idea.

I agree that overall the RF harness is very well done. Nearly all the wires are labeled on the wire itself. I guess my biggest complaint is the lack of ability to add circuits to the fuse block (the fuse block is full). I’ve added a simple relay powered ignition cutout security system and a flash to pass feature with the turn signal from Russ Thompson. Holley Sniper has been fairly straight forward with the RF harness too. I added a relay to the sniper ignition switch connection for clean power and that has required minor dissection of the harness. All in all, not bad at all, but as stated in my original post, I like to know how everything is constructed, so I’ve spent a lot of time being very methodical in the process.
