Does anyone have a diagram of how to make a relay harness for 9006 hids? I already have ALL the parts required....................when the local CC went out of business I bought pretty much the ENTIRE installation bay parts. So have tons of 30/40 amp relays, fuses, connectors, wires, etc.....

there are all kinds of sites that have that info, but I'll explain how it works real quick for ya

thats the quickest diagram I could find, but it all works the same way...
essentially, you take the original headlight + wire and run that to terminal 85... then you take +12v from the battery (make sure you install a fuse, 25 amp is sufficient, 30 will work), and run that to terminal 30... Terminal 86 needs to run to ground, does not need to be high amperage... terminal 87 is the positive wire that you run to the light themself (ground for the headlights is not run through a relay and can be any standard chassis ground) if your relay is a 5 pole relay, terminal 87a will be unused (it is only used when the circuit needs to be closed when the relay would technically be "off")
please make note of my edit if you got this in your e-mail, I confused 87 and 87a the first time through
