I'm rewiring my car (71 dart) and removing all the extra B.S..
It's almost never driven at night but I want headlights. This box has 2 fuses in it for headlights. I thought the headlight switch had a breaker built in, so what dose this box Do?

Thanks again!
 
Straight screw cover, no markings = not a Chrysler part. Someone added that. No idea, you'll have to trace the wires.
 
try it with and w/o fuses and see what it does -are your headlights working now or not?

Depends...

Yea, you could "chuck it" and use the headlight switch as it was originally built.

The other option is to wire everything with the relay in place. It looks like you have some wiring "issues" anyway. The relay is a good piece to have as it takes the load off the old headlight switch and will help you have brighter headlights. You could also replace that relay with two Tyco relays, but if that one works, I don't see why you couldn't clean it up and use it.

Your choice.....
 
Using headlight relays on these girls is a great idea, but I just would not use THAT one. Looks like it's pretty bad shape. Remove the cover and look inside. Crackedback on here sells a little kit for relays.
 
Ok I will save it and move it to the passenger kick panel where my new fuse block is.

Yes the headlights did work before I removed the bulk head connector.

This is a race car so all the "extra" wire, old wire and B.S. is getting pulled out.

Thanks again!
 
On second thought can I just but 2 new relays from kragen? Smaller is better for me and this uses old glass fuses that are getting harder and harder to find.

What part number is the Tyco relay?

Thanks again for all the time and advice.

If you'e over 20 years old, you'll be able to get the glass fuses to rest of your life. ...they're not going away anytime soon. ....

Did they put a minimum age requirement on the glass fuses? Never saw that coming! ..well whatever it takes to maintain supply for 68 year olds is good thing. I love those little suckers..'specially when you're pry 'em out and they bust in the middle and shoot glass at your eyeballs..
 
IMHO, the relay you have is very simple to mount and wire. It takes care of both high and low beams too.

The Tyco relays are nice, but I'm sure the next question is "how do I hook them up", followed by "should I buy this expensive wiring kit?". A goggle search will find a bunch of ways to wire them and I think the wiring kits, as nice as they may be, are expensive provided you can do the work yourself. But... you really can't beat the simplicity of the relay you have. Again, that's my opinion.

FWIW, I buy these: https://www.amazon.com/gp/product/B000P61E36/?tag=joeychgo-20

and then wire them using a socket like these: https://www.amazon.com/dp/B00KXFIGTY/?tag=joeychgo-20 although I can usually find the sockets cheaper on eBay.

I always post this for someone that is working with a wiring harness. A piece of plywood and some finishing nails makes things easy... and it's the way they build wiring harnesses in many industries. Lay it all out and replace one wire at a time and then wrap it with non-adhesive tape.
