91 crew cab speedometer wires
« on: March 03, 2012, 08:42:35 AM »
I was wondering if anybody had one and could tell me what color wires are that plug into the speed sensor on the gear drive transfer case? Thanks for any help

     If you do not get an answer here, you might check over in the suburban section to see if you can find the answer there.

#2: There is no such thing as impossible, it just takes longer.

I've got one and can tell you!  I can look at it when I get home.  I also have the factory wiring manuals so I can give you a diagram if you need.

What seems to be the trouble?
