Ive got an 88 rex. Its got a d16z6 on the stock Si harness. Everything is fine i just have to get the ecu harness adapter. My problem is that when i turn my lights on my thermostat reading and my gas hand goes nuts. Also my right turn signal stays on ever so slightly Only with my headlights and not with just my parking lights. My other question is can anyone help me find my headlight relay. I have not had highbeams in forever. I just am not the greatest with my cars wiring. Thanks for any replies.

Most often when you have erratic electrical gremlins its almost always a bad ground.
I'd check the ground at the t-stat housing and make absolutely sure its good.
Not just look at it,loosen it and give it a look to check for corrosion as well.
I can't tell you the "fun" times I've had because of bad conductivity at that spot. :lol:

Yeah... Check your grounds. The lighting grounds to the inner fender just behind each headlight in the engine bay. Also check the transmission-to-frame-rail-to-negative-battery-terminal cable.
CRXs don't have headlight relays. Power is switched directly by the lighting switch on the steering column.

Correct

Your highbeams run off seperate power/grounds. If their not working, the power/ground to them is messed up.

Like the previous guys said, 9/10 its a bad ground. and take Ollie's advice, and do more then look.

I had my PS headlight go out after I did my tuck. I completely untucked it to make sure the ground was proper, and it was, wtf? I couldnt figure it out.
Then I noticed after hours and hours, that the wire had snapped, but only on the inside, the rubber coating hadnt ripped, so I couldnt see it, had to feel it.

the 88 i'm about to pick up has the same problem, kinda. when you turn the high beams on, the gas guage goes to full. it makes me think of a crossed wire, due to voltage being passed through the high beam switch, to the gas guage, but i'm hoping it's just a ground. does anyone have pictures of the main grounds? or is there some place i can look online?

My highbeams stay on because hey are the only ones that work. I just relocated them to the low beam slot. Let me know how you fix it if i dont fix mine first.

You guys need to go to Honda-hookup.com and download the free manual they got, has all the wiring diagrams, and a seperate list of just the ground.
With it, and a spool of wire, solder gun, and shrink wrap, you can wire your whole car.
