On my 67 Chevelle;

Due to a poorly installed column mounted tach that allowed the mounting screw to short out something inside, my turn signal assembly and harness needs replacing. It has fried and I am damn lucky I did not lose the whole car over this mistake.

I have the replacement now. The assembly itself looks identical but have some questions on the wiring.

The female connector under the dash has 8 terminals, with the following wires going into it. From left to right they are

white,green,yellow,purple,brown,dk blue(2),Lt blue(2),black

The male plug on my new harness has only 7

black,pink,Lt blue,white,dk blue,yellow,green

Do I have the right assembly? I see in my service manual seven wires going to the signal switch and an eighth going to the horn. Do I have to run this eighth wire seperate? I dont want to do any more damage.

Thanks in advance
Dunc

The real question is - are the wires from the old, original turn signal switch the same color and order as the wires in the replacement switch?

The colors for the wires in the vehicle harness usually are the same color as the signal switch wires but sometimes they vary.

The additional wire may be for the key warning buzzer. I think that it was required starting in 1968. The switch may be for a 1967 without the key warning buzzer.
