S15 Headlight Wiring

My crew and I have just about completed a S13.5 comversion, but we are hung up on the headlight wiring. Does anyone know how to change the wiring on a pop-up to S15 headlights. Any help would be great.

take a test light, then probe each each wire on the factory headlight harness with the parking lights on. if the test light its up, then you have found the wire for the parking lights. to confirm, turn the light off, and the test light should go off. then you mark that wire. then go to the next, you turn on the headlights fully now, and you use the test light to probe each wire until you see the light come on. to confirm, the test light would be off when you turn the headlights off. then find out how big are the male connectors on the light bulbs for the S15 bulbs. then cut your factory harness and buy some female connectors that will fit the S15 bulbs then crimp them on.
