Ok, lights are finished. For the reverse lights, I wanted to be able to have the back up lights come on ONLY if the headlights were on and the unit was in reverse, OR, if I manually switched them on to use as work lights while loading a trailer, etc. So I used the back up alarm wiring harness, tapped into the green wire to ground the 30 amp relay when the buggy is put into reverse, that wire goes to terminal 86 on the relay. Terminal 85 on the relay goes to a tap into the brown wire noted above, only hot when the headlights are on. Terminal 87 goes to an un-switched output on my Eastern Beaver PC-8 fuse block. Terminal 30 goes to the back up lights. So, if I am in "stealth mode" (no headlights), if I reverse no lights come on. If I have headlights on, and go to reverse, the backup lights light up.
To accomplish the manual override, I wired the switch on the dash to pull power from the fuse block (an un-switched, always hot terminal, since I want to be able to use the back up lights as work lights without the key being on), and ran the wire from the switch to the wire coming from terminal 30, between the relay and the back up lights. (BTW, the back up lights are grounded directly to the frame). So pushing the dash switch turns the back up lights on as work lights.
Seems like it's going to work. If I keep leaving the work lights on and running the battery down when parking the buggy, I will move the feed wire to a switched outlet on the PC-8. But I doubt I do that, I should only need the lights when it's dark....
And I can't say enough good about Eastern Beaver and the PC-8. I will try to post up pics later, after I clean up the rat's nest of wires, but the PC-8 is ultra reliable (used it on two different cycles going to Alaska) and the perfect size to fit in the little hole next to the air pre-filter.
