Wiring a headlight relay

[Biggredd2069]

Aren't those just the holes for mounting the relays?

If they are thats funny. No instructions so I was assuming it was just a heavy duty connection point. I'm gonna get a pic today of the full thing laid out better.

Me too

Oh. I was going by the diagram and saw the single fused power feed.

Plug N Play is the way to go. Crackedback sells a real sanitary setup based on your car in two and four headlights. He’s over on the FABO.

Those are mounting points.

I will definitely check for corrosion and wear as I do want it working proper. I do have a tester and will go through the motions. I've read this is a good upgrade regardless. But I still don't see where specifically you guys are splicing this in within the engine bay. I understand the idea of how to wire it up, I'm just confused where you are splicing in. The connections on my harness lead me to believe I'm just unhooking something and plugging it on there. Am I cutting a wire? or just unplugging/unscrewing something?

My relays are installed in front of the radiator support. My harness is self made. No existing wires, of the car, were cut. The trigger for the relays comes from an 18ga wire with a male spade for the original headlight socket ( I replaced mine with better sockets), and then female spade for #86 on the relay. I can remove the new sockets, plug the original sockets back in and I am ready to go back in OEM condition if I want.

ok. I got it figured out. There were no instructions in the box. It was plug and play. What confused me is you unplug 4 headlights but only need to plug one back in to the original wiring. I was assuming 4, or at least (one low beam, one high). you just plug one headlight into the new harness. I just assumed the relays plugged in to the wiring somewhere. lol, clearly wrong. My windshield fluid reservoir is dry rotted so I took it out and have a nook in there where I put the relays. All is good. Thanks for your time everyone.

happy it worked out.
Thanks for the update.

Glad to see you got things working. I kept my old harness, and just plugged my new home rolled harness into the driver side low beam socket. Have had nothing but excellent service from my setup since then too. People scare themselves of electrical issues too much. Be mindful of safety, follow basic rules, check safety again, and you will be fine.

if a guy took a diode and put it in between relays #86 trigger pins

thusly

when i flip on low beams relay its ONLY low beam relay activated
AND
when i flip on hi beams relay it would be BOTH relays actiavted

do i mucho savvee?

trying not to fry -

*i get you shouldnt run both filaments lo/hi in the same bulb. i was thinking about running 4 hi beams / 4 singles vs. a combo hi/lo bulb. anyone ?

That should work, but I'm not sure if that's the best way to light up the road or not. I'd be more tempted to use a hi/lo combo bulb and then wire a switch along with the relay. I think I've seen references to doing that, with possibly a shorter bulb life, but the switch lets you choose when and if you want it.

thanks Mr Big John and Merry Christmas!

i actually ramped up the question and sent email out to slantsixdaniel stern lighting.

assuming i skip the 'hi' side of the combo lamp and install this diode - im seeing what Dr. Stern says if im gonna die or not.

thanks for the electricals confirmation though. im self taught 300-n-1 electronics kit 1974 style so i appreciate the look-over

The diode idea should work for that. If you run 4 hi-beam bulbs instead of the hi/lo beam bulbs in the outer pair, oncoming drivers are not going to like you. It will also be illegal, which in itself may not be a problem, unless your lights happen to piss off an oncoming cop. I would do what Big John suggested and use a switch wired in series with the diode.

The diode will do as you like with the relays. I had one of those 300-n-1 kits from Radio Shark myself! Got it for Christmas that year. I recall making the telephone pickup circuit Christmas Day and then calling my aunt and rapping w her through the output speaker, which acted as a dynamic microphone also, agitating the inductive pickup enough to induce current in the old telephone receiver. I ENJOY 1970s state of the art electronics! Remember the INTEGRATED CIRCUIT in that kit?! It had what, 9 discrete components in it?
