    I need to install some reverse lights on my back rack. Can some one tell me the best way to do this. I know how to mount them but I need to know how to wire them.

    I am not an electric guru but I would run a hot to your battery and ground to chasis then run your wire kit to your reverse light in the tail lights. My guess. I have mine mounted allready but yet to wire them. If I can find the wire diagram I could fax it to you.
  3. I will be the first to ask:
    do you want to manually control them (marginally legal)
    or have them come on with the reverse gear ??

    second: how many watts are your lights -- that may require a relay to run them
    thru the backup lights

    I would like them to come on with the reverse gear but I would like to be able to manualy turn them off. I really just need them for backing up while plowing

    So break the ground,

    Run a live from the trailer wiring harness to the lights, GM it's a light green wire. also can tap the reverse lights on the truck,
    then just run a ground wire from the light to a switch. and a ground from switch to a good ground in the cab or back to the battery. and if you want a light switch just run a power from fusebox to the switch.

    and use that as on off. Just have to watch that they lights don't get a ground just from the mounting. But thats just a matter of buying a light with a ground lead.
    They will always have power when in reverse, just not be grounded when you don't want them on.

    This also saves you having to run a power from reverse to switch, then to back of truck, which is stupid when the power source is back there. Mind you I think you said backrack, same princple works, you can find the trailer wire harness (assuming you factory one) and tap it near the cab/box.

    We do this for a backup alarm on the Salt trucks. Be able to control what time of day and place the alarm is active makes for happy neighbours.
