headlight relay
 

do you run a headlight relay? and where did you put it, could you post a photo? I have been thinking of putting one in my 36 pickup

Brendan, before you do that, test your horns with jumpers to see if a relay is needed. I don't think a '36 has a relay 'cause the horns don't draw that much juice? I believe the '36 horn is adjustable?

In any case, your horn button simply grounds the (pos) wire closing the horn circuit. Relays are normally placed close to the unit, with a heavy gauge hot running to the relay.

Are we talking headlights or horns?

Oh, I read it wrong! Yes, a relay for headlights can work wonders! One relay for high beam, one for low beam, up close by the radiator.

Mount your relays where you can keep the power runs as short as practical. I mounded mine near the radiator on the frame rail. But, I wanted them to be seen because of the setup I am using, if you are using the plastic ones you might want them more concealed.

On a 36 with the stock harness, don't you have to cut into the harness to access the wires to add relays?

Re: headlight relay
 

Yep. I attached a diagram. On a pre-foot dimmer switch you would splice into the high and low beam wires from the lighting switch at the bottom of the steering box.

I found a big difference after wiring in relays , we did both high and low. even better again fitted direct replacement APF halogen globes.
