I bought a set of diamond eye projector style headlights off of Ebay that have the H4 bulbs in them. Is there a special way to install these headlights in a 92 Toyota. There were not instructions included and there are 2 orange wires and one black wire on the pigtails that came with the headlights. I know the black wire should be the ground wire. Do I need to customize my headlight wiring harness to make these work?

Thanks,
Doug

 

Get a harness from 4Crawler - will hook right up and you'll get more light out of the bulbs too.

 

You can see the way the headlight bulbs are wired on my web page:

You can run them as-is, assuming the lamps are wired to match what Toyota uses, just plug in the 3-pin connector. You should test the voltage at the beack of the lamps and make sure it is adequate. Many Toyotas suffer from excessive voltage drops to the headlights.
