Grounded yes. To the body? Not directly. Here's my feeble attempt at providing a
diagram (wish I remembered which was 30, 86, 87...)
light hot--------------hot 12V relay to 12 volt source
light ground to body to switched 12 volt
to rocker switch --- to ground
Most people run the relay to switched 12 volt through a switch. With this you
have +12 going through the firewall, under the dash, through the switch and then
to your switching source.
No need to do this. You're just grounding the relay, not the lights themselves.
They have their own grounds, which you ought to take right off the back of the
bulb to an appropriate terminal on the body. (Not the bumper and not through the
mount to the bumper)
If you ground the relay through the switch IMCO you have a much safer switching
Am I on track here? What happened to my original question? What the hell was it
anyway ;-) Oh right, where do I put the switch and should I up the power on the
