Anybody have a wiring schematic for the tank selector switch in the cab and the fuel selector (6 port) on the frame rail? This is off an 82 GMC 6.2 diesel. Thanks.

Having trouble switching between tanks? I've replaced 2 of these 6 port valves (2 different trucks). It's a major hassle to get to the 2 bolts that hold the valve to the frame but I have done it with just a regular end wrench. A ratcheting end wrench would make it much easier. 13 mm I believe.
