I am getting my Grandmothers car running that has been in a garage for 17 years and mice have chewed several wires. I am having trouble locating the termination points for several of them. They come out of the harness beside the vacuum valve differential lock and I am sure 2 of them terminate there but I have 4 that I have no idea and have spent hours researching without any answers. The color codes on the remaining wires are GY,BW,BR,B. I am pretty sure the other R and B go to the valve. Thanks in advance.
