These are going on my shrock front bumper. I didn't tap into the parking lights or headlights because they will never have a cover on them, and if i accidentally leave them on i will hopefully notice (shame on me if i don't).
But I have another pair I'm going to mount on the roof later on (hopefully along with some air horns) and these will be tapped into the parking lights.
When i do that i will post it up.
Muzikman is right in wanting you to go to another power source. You will leave them on.
Like um my Dog turned mine on. Ok let me make another suggestion, Take the 5 terminal and run it to the ING ON Cig lighter POS Top Cig on dash or easier to get to, open the cup holder and quick tap the Pos wire going to the Cig Lighter in rear console. This gives you power on when truck IGN. is on (Running) and turns off when you turn off the key. Be sure your fuse is in line and close to your switch but also covered by fuse in Cig circuit (10 amp) Kinda too beefy.
I highly suggest this, It's only moving one wire, easy easy and worth it.
I think I have heard you say protection 1st? And bonus is, it's a down line circuit tap, a harness that you can cheaply replace, the MC rule.
For others that are doing Mods and want a few, You can run a line from that ING circuit to the kick panel, put it on a breaker with terminals and use it for power for any switch the uses a relay that runs anything you don't want left on. When using a relay, the power to trip the relay in very very small and this circuit can handle it easily.
One side would be power in from Rear CIG POS and other one you terminal and put POS to any switch that will trip a relay.
Anything hooked to that will not tun on unless key is on. MC
