I’m curious – do any of the wiring kit manufacturers offer schematics, diagrams (or at least spreadsheets) explaining the overall and complete details of their installed kit like an OEM layout?
I’ve always been a champion for Ron Francis wiring, in spite of the fact they are the high price leader - offering none of the discounted component prices of their competitors. But after all these years I finally came to the realization how frustrating it is they’ve never offered a wiring diagram or schematic for any of their products. Nothing came with the kit and nothing is available online, just instructions like “you will then run the wires to the panel and connect green to #15, blue to #13, yellow to #14”, etc. This does allow a novice to wire a car, but doesn’t provide any meaningful information for an experienced person, and makes debugging or modifications later a real pita.
After nearly twenty years since installing a Ron Francis wiring kit, I just completed running new wiring from the dimmer switch to the headlights, eliminating the last remaining portion of the original 1960 wiring. I didn’t install the RF circuit during the original install as the kit wiring was overly complicated and didn’t allow the grille to be removed as a completely wired assembly.
I didn’t feel like drawing wiring diagrams, so I did the next best thing and created a 3 page spreadsheet that explains where everything goes, including which wires enter each position of the dimmer switch. One detail still missing is the gauge of wire used in each circuit (which I would liked to have had). I wish I had done something this thoroughly years ago. Here’s the first page as an example;
