coming from knowing very little about automotive electrical work i went with Ron francis. I found it easier then i expected. I was a bit worried that i would get lost in a rat nest but it was very straight forward and very simple to install. There were a few stop and think moments but i believe it was mainly i would work a weekend on the wiring then not go back to it for a month. So my brain had to refigure what i was up to last.
I called ron francis tech line twice and it was an immediate response with no hassle about anything. Once was about the steering column wiring and turned out i should of been smarter and tested the wires (stupidity on my part) The aftermarket signal switch wires were different colors.
The other time was about the hazard lights and clutch neutral safety. If i would of read the back page of one of the instructions i would have sorted out the neutral safety and the hazard lights just needed to sort out terminals.
I personally would not try another company since i am extremly happy with ron francis. All the wires are labelled and easy to trace and does not take a rocket scientist to sort it out. Just need to know how to solder, splice, shrink tube and attach terminals.
Follow the instructions and do not look at a service manual, unless sorting out wire colors at a light or switch. Mounting the fuse box took some thinking, but after that it was like riding a tricycle.
