1983 K5 6.2L, i have all the Diesel Page books and bought the new controller + plug. But in the book it says to install the controller on the DS fender for a warm climate. I live in Toronto Canada so I dont have any issues with warm starting just when its dead cold out.

In the book it says that the factory location was on the firewall above the motor, does that location work best?

Secondly Im a little hesitant to do this repair, since i dont feel like i have enough information about which wires go where. does anyone have a colour coded diagram?

This truck is my daily driver so i cant afford for it to be out of service

thanks
