I want to install a set of fog lamps I have as daytime running lights. So I need the lights to be on whenever the car is running.
I’m a bit of a wiring newb. This doesn’t have to be a permanent either. Obviously I run the negative wires to the ground. But where should I wire in the positive wire? Just run it off the positive terminal on the battery? It’s a '91 Soarer BTW…
I haven’t done anything like this on my current car, but on my old Integra, I just wired it to the fuse panel. You can pick whatever fuse you want, but something that’s on whenever the car was on (radio, whatever) is what you’re looking for. I think there might even be a ‘constant power’ fuse that you could use. Just make sure you use a fuse that’s the proper resistance for the lights.
I soltered mine straight to the actual fuse rather than the wires in the panel, so if I ever blew that fuse I’d have to redo it. But that lasted the entire life of the car. Realistically, fuses don’t blow that often unless you’re screwing with them.
Pin 30 - Fused pwr from battery(set the fuse size to be slightly larger than wat the lights draw. Amps = Watts/Volts)
Pin 87 - Positve side of ure lights
Pin 86 - Positive keyed power(radio, wipers, anything that will only run wen the key is on)
Pin 85 - Chassis ground.
Pin 87A - not used
Ground the lights to chassis and that should be good. U will need to find a fuse holder for the wire going to 30 on the realy, u should be able to get them and relays at crappy tire or mopac.
