The current crop of 1969 headlight harnesses from Metal Alloy have a flaw in the wire colors. This repro harness does not come with the firewall plug, so you have to re-use it, and there are decent instructions for where to put the wires. Anyway, the harness comes with two green/black wires: one for high beams and the other for the washer pump, but they are not distinguishable. The instructions states that the washer pump wire is light green/black, but it is identical to the high beam wire.
In the past 3 months, I've had to re-pin 3 of the repro headlight harnesses for international customers.
Sorry for mixing up years, but wanted to post that Metal Alloy's quality control has been slipping ever so slightly, so it is important to double-check everything before hooking up the battery.
