GM used this for sealed control of a bunch of circuits on the 86 and later squarebodies and the 1st design GMT400 trucks.
Good advice! I got one at AZ and it worked, but you could see the difference in quality between it and the original one.

Hatzie I have some more troubleshoot questions. Would you like me to PM you as not to clog up this thread or start a new thread of my own? Thanks again for all of the great information!
