Re: are there certain relay harnesses for specific cars?

Relay harnesses begin with a couple of relays, some wiring & fuses, and headlight connectors. You have one-headlight, two-headlight, and four-headlight models. Headlights (or bulb connectors) come in H1, H2, H3, H4, H7, H8~H13 for European lights, and then there's US/NA designations for HB1 thru (I think) HB13 currently, with a few HBs still missing in the sequence. There is also the variable of your vehicle having ground-switched headlight wiring, as in the case of Toyota and some others, where the bulb positive terminal is always 'hot', and the lighting circuit is completed by switching to vehicle ground. So, write down what you have on your car for the FACTORY headlighting configuration, and that's probably what you'll need to buy; a harness made just that way. No, it won't say 1998 Honda Civic CRX or some such on the package, but it will be the correct harness for your vehicle.
