hey i just picked up a new set of the Hella 500 fogs, wondering if anyone is an expert at installing them on a 98 subaru. if so please PM me. if you help install cash is involved. or if you could give me a good reference on how to install that would be great.
Disconnect your battery Go off your alternater with the (red?) wire, that runs to the relay (blue box) that feed the positive (blue?) wire, take the ground (balck) wire from the lights and connect it to your negative battery terminal, run the relay switch (green) wires from your relay to inside the car. Find your headlight power line (to the headlight relay, not for the actual headlight). Strip a small part and crimp the open ended green wire to it with the provided blue clamp. plug everything into the switch provided. When your headlights are on, the switch should light up, then when you flip the switch your fogs come on. You could also just merge the pos. neg. lines for your existing fogs into the pos neg line for the 500's. Note: I used my FF1000's for the wire color reference.
I'm going to assume you don't have factory fogs that you are replacing. If you do, lthen just wire the lights to those and be done. If not, yoou can probably still do a really clean job by getting the switch and relay for the factory fogs and put those in (the wiring harness likely includes the wires already, easy to check), and then again, just tap into the wires at the connectors down by the fogs. That would be the cleanest install. Otherwise, what MethodlesS said. I went a different route with mine, but when I want to, right now I can throw 660w of light forward, so my setup is a bit more advanced than just the Hella 500s...
