Headlight question....

[DeckerEnt]

Has anyone ever adapted 4 eye headlights to an 89 wiring harness? I need to do this for my coupe. Where can I get a wiring diagram book for an 86 so I can re-pin the headlights to the 89 harness?

you can splice the harnesses from the newer all you need is the high low tied in the older wires have 4 wires where the newer only has 3 what was done to my old 79 with a 93 upgrade the cheap haynes manual has the diagram in the back. keep it up the coupe looking good
