I bought 2 sets of headlights for my 69 mustang. White for the inner high beam and multi colored for the outside low/high beam. Dash has to come out. Some time involved but not difficult. For the single colored the wires from the harness reached the front of the car. The multi colored wire was way to short. I called Tony at RedLineLumTronix LLC. He was great. sent out an extension wire. He took the time to listen to some of the issued I had with wiring a 69. To include the longer harness wire, longer pig tails and a few other ideas. CJ sells the painless and american wire relay kit for the headlights. Buy that too. They look great! I have pics but I don't know how to load them on CJ's web site. Can't say enough good things about Tony.
