how to find the sending unit power wire

Alright, I'm trying to clean up all the wiring that came for the dual factory tanks. Fuel pump power line is taken care of. Now I have about 6 wires to choose from as to which could be the sending unit power. Theoretically there should be two. Last night I hooked the battery back up, turned the key to power, and tried all the lines with the test light. Nothing. Just to make sure the test light was working I turned on the taillights, I got a signal there. Anyone know how to track it down?

Pretty sure the taillights wouldn't have worked on a dead battery ass clown.

If youre going to remove the wiring all together and just run set to the fuel cell then just delete the left set and use the right side. Also look at the firewall near the column for a plug that the wires that will route to from the tanks.

Not sure that I follow you on this. What do you mean by left and right side sets? The wires run from the switch in the cab in a bundle to a bigger bundle behind a lot of stuff I didn't want to take apart. Then all the wires come in a bundle down the driver's side of the frame.

Does anyone have a schematic for a 87 or 87-91 burb/blazer? I don't have one just an older one.
