Has anyone got a pic of the wire colours for the 3 pin plug that goes into the back of the headlamp unit , I have one light on high the other low, then when I put it on high they swap over which is high and low so one wire must be in the wrong hole, a pic of a plug for a 1970 car would be great
Thanks Brian

I've got my '76 torn down. Maybe they're the same. If looking at the back of the plug; white on the right side, brown on the left and yellow on top.

Here you go:

If the wire colors at the headlamps look correct, the next spot I'd double check is the wires at the fuse panel and make sure those didn't get swapped around. The left and right high and low beams each get their own wire at the fuse panel, 4 total wires. Starting from the left side of the fuse panel, if you check the outgoing wires (the terminals facing the front of the vehicle) it should be 2 white wires (left and right high beams, respectively) followed by 2 yellow wires (left and right low beams, respectively.)
