Alright, so I got my OTRATTW switches mounted and wired to the point where the switch lights come on when I turn my dash lights on, etc. However, I can't figure out how to wire the relay. I'm confused on what wires off the relay go to the battery, to the light bar, to the switch, and to the ground. Could someone please inform me on what number on the relay serve which function? Thanks.

 

Using a standard Bosch style relay?

Red ground
Black +12V (yes I know that seems backwards, but that is how they are wired)
Blue power to device
Yellow switched power

 

I know when I used a relay, I used a video on YouTube. It was called like how to wire an automotive relay or something similar, very straightforward

 

+1 for YouTube. I usually find my solutions on here and then find a corresponding video to DIY. Its great since you can go step by step and pause the video in between.

 

I figured it out with the help of YouTube. Thanks for the input

 

Just ordered my new bumper which I'm going to have four LED pods on. My problem now is I don't know how to wire all four lights to the one switch. Would I have to have a relay for each light? And if so, how would I connect all of them to the one relay tab on my OTRATTW switch? Thanks

 

Someone correct me if I'm wrong, but you should just be able to connect all 4 wires into 1 lead wire that goes to your relay. You should only need 1 relay and 1 switch for all 4 if you want them all to turn on and off at the same time.

 

This is how I've always done my lights
