1984 K10 Dual Tanks Power Question
 

Is there a fuse for the selector valve that is under the truck?

This truck was "Kid Tested" between the stupid tacH & half ass stereo install. I am not sure what is what on the fuse box.

The NL2 option tank switch should be wired directly to one of the Pak Con I Ignition "A" (hot in run & start) accessory plug-in points on the fuse block. In 1984 there are three "A" sockets along the LH edge of the fuse panel.

In 1984 the "A" plug-in points are fused with a Yellow 20A fuse on the LH top row of the fuse block marked IGN.

This is all in the 1984 GM wiring diagrams. PDF's are below.
The fuse block is on the last page. The NL2 sub harness diagram is on the second to last page.
