I'm in the procwss off changing my under the dash wiring harness in a 67 Chevelle SS 396. The old harness was destroyed by fire. On the old one there was a 3 wire connector for the wiper switch black, light blue ,and dark blue,with 2 speeds. The harness i'm putting in came out of a 67 SS Malibu, it only has a 2 wire plug pink and light brown. Is there a 1 speed switch and a 2speed switch. The motor has 4 wires a black by it self and 2 yellows and a light blue plus another plug for the washers. Do i need a different switch or can i had a wire Thanks Dirks SS

Pink and lt brown (tan) is the fuel gauge connector. The wiper switch connection should be the same on both harnesses. No single speed wiper for 67.

I found the 3 wires for the switch someone cut the end off. What i need to know now is. There are 3 terminals on the switch . .. these are the terminals what order do they go I think the first one is black then i don't know lightblue or dark Thanks Dirks SS

Looking at mine,with switch installed properly,going from the top (dash), to bottom........ Top is Black,next one down is Medium Blue,space,Bottom is Light Blue.
