From a discussion on another thread, here is a quick sketch of a way to hook up headlight relays, using CJ style wiring numbers and device depictions.
I've finally started adding a headlight relay kit to one of my Jeeps and I used the above drawing as a starting point. One think I quickly decided is that I didn't really want to chop up the factory lighting harness. My old CJ had a lighting kit added to it when I bought it, which allowed switching between two sets of lights with a toggle switch. The other set of lights was not present on the Jeep when I bought it so the switch always needed to be in one position for the headlights to work. The harness used an H4 plug out at the driver's side headlight socket to get power from the headlight switch and fed it through the harness. At some point the toggle switch failed and I needed to get the lights working. Since the harness was an add on to the factory wiring all I needed to do was pull the H4 plug and swap the headlights back to the factory lighting sockets. This is also how I would prefer to add my headlight relay wiring.
So, I chopped the H4 plug from the failed lighting harness and have been building an add-on headlight relay wiring kit. I revised the previous drawing to show the new details and made terminal numbers match the relays I purchased. The terminal numbers match a couple of different relays but probably won't match with all of the possible relays one could use.
The drawing includes a diagram of the relay function so that its operation can be copied to whichever relay is purchased. Suggested wire sizes are on each conductor as well as colors that match the factory CJ and YJ wire colors.
These additional files are my "pre-fab" versions. I'll plan to replace them with final versions should I make any changes during the build process.
I know, they are making my life alot better right now. I can make a good diagram with what I have now, but I think I could make a bad @$$, over the top, diagram if I could get a copy of what I have without having to cut and tape it together. I will work with what I have, but let me know if anyone hears of someone that has access to the real deal.
