Plug and play - Headlight Relay Kits

Yes, to follow up dfnsmn34... so if I received this, how would I know how to install it? I see you say essentially plug n play, but how would I know where to attach it to, and maybe I can't see well in the photo, but it looks like some of the ends are just wire (no connectors)? Is it more obvious to hook it up than it looks in that pic? I'm not afraid I couldn't do it, just not sure I'd know even what to do.


Kit will come with instructions and a wiring diagram/schematic.

The wires will be terminated in the kits. The pic was representative of what it looks like.

The 5 sets of wires exiting the relay blocks are really hard to confuse. You have 2 sets (short/long) with ceramic headlight plugs, 1 set of main power with fuses, relay trigger with a specific end and a ground wire set for the relays. They are all plugged into the relay block, you don't have to plug anything into the block.
-------------------------------------------------------------------------
Disconnect battery, find spot to mount relay block, drill holes and mount

Put a little dielectric grease on the terminals/connectors
Disconnect the old wires at the headlight and reattach the new ceramic plugs. I can't get to the original headlight connectors, hands too big, so you may likely have to remove the headlights to get at the plugs. Short set to drivers side, long set to pass side. Attach grounds from each bundle.

Attach power leads to alternator battery output stud.

Plug relay trigger into the original dr side headlight connector

Attach ground wire for relays

That's about it




Looks like a great winter project for the Demon, will it come with a schematic? Do I have to let you know ahead of time which location I choose for the relay mounting? or will it work on any of the three locations you mention.

Yes on a schematic.

It's best to tell me where you would like to mount them. That way there isn't a bunch of wire wound up somewhere because it was too long, or worse too short. I try to tailor it to each location. Best to send a pic where you want to put them

I also need to know if the alternator is in stock location and whether it's a V8 or slanty. Slanties are really down low


If it took more than 2 hours to install this, I'd be surprised.

A pic of how I ship it. I used a different HL connector end on this one. Each main wire set is in a baggie and will be labeled with a tie strap label as well.

I think I'm putting this one on my car, I use what I build...
