Just wondering if anyone on here has installed a relay kit on your headlights. I ordered one from NPD and it really was a true plug and play. But now I have a problem with high beams, don’t have them. There is no way you could screw up the install, but if there is a way I’m sure I did it. New dimmer switch and still no high beams. Rechecked all wiring, nothin out of place. Replaced both relays and then had no lights at all. Put the original relays in and had low beams, no high beams. This is on a 66 coupe with the 200 6 cylinder. If you have any ideas, please let me know.
