wiring help! is this safe???

Alright, I'll hook you up to clear up any confusion. Remember, this is a reference...I take no responsibility for your actions.

The red arrows represent the actual worst case current draw. I also labeled each wire as I understand it from your plans and descriptions. I'm also assuming that you aren't tapping power from a fog light or something inside the cab, so you'll have to run another wire from the battery. Typically you shouldn't do anything smaller than an 18 gauge wire for the relay control. Since this line is low current, a 5A fuse is readily available and sufficient for this line.

 

Thanks!i got all the wiring done! I used all 10 and 12g wire with two 25a fuses and A relay

 

Just a reminder, if you're using a 25A fuse to protect a 12g wire, just be sure it's quality wire that can handle it.

 

I used the 25a fuses on the 10g wire

 

over build?
