Fuel Transfer Wiring Help

[FMJ]

I have a 1028A3, purchased from GSA last year. Before it was auctioned the fuel tank selector switch and associated wiring was "removed" I have located the pieces needed to make it right but I can't figure out where 2 of the four wires go.... (pink and black) None of my manuals show a dual tank wiring schematic.....

Does anyone have the instructions provided with the Dually conversion kit that show the installation of the second fuel tank, transfer valve, and the associated wiring?

Thanks in advance,
Ed

Does anyone have a mid-80's Chevy P/U with dual tanks?, I need to know where the Pink, and Pink/Black wire's from the transfer switch on the dash go.......

What are the rest of the wires... and where to they go?

What are the rest of the wires... and where to they go?

4 total, green/light green these 2 go back to the transfer valve, the other 2 aforementioned wires go into the harness under the dash on a factory equipped dual tank truck. I'm going back to the junkyard on monday to scope out the destination of the pink/blk and pink wires in the truck I removed the harness/switch from today. Unless I can figure out before then where they go.....

I'm thinking they are power for the switch/transfer valve, but afraid to assume polarity based on the colors....

Upon further review.....

Pink/Blk is actually Black/Negative and a Pink is Positive and they supply power to the transfer valve via the dash switch. The fuel gauge shifts as it should to reflect levels in each tank, SWEET!

Now all I need to do is replace the 6.2 blown head gasket engine in the truck.....

FYI, I'd bet that the "pink" was really "red." Traditionally, in automotive wiring, red is hot, black is ground, and other colors are for other things, as is the case of this switch.
