Hey does anyone know where i can buy relay harness's. I am going to use them for my fog lights, led lighting, along with an 80amp one for my power inverter.

Also what kind do i get. 4pin or 5pin? whats the difference?

 

5 pin relays are double throw relays. They have a normally closed pin that will power something when the relay is not active and then the normally open pin which will power something when the relay is active. If you do not need this, then you can get the 4 pin.

 

ok thanks. I found some 80amp relays that can also be used as a battery isolator. Will one of those work for my inverter

 

do you want the relay or the harness or both? www.partsexpress.com is where I buy all my relays.

 

i want the relay and the harness. They dont need to be water tight since they will be inside

 

partsexpress sells both for great prices

 

what size wire would you recommend going to the switch

 

well the easiest would be to put the switch on the ground wire. If it is a short ground, 18ga should be sufficient.

 

ok thanks. Can someone draw up a quick picture of how i would wire a 5 pin relay
