Dual tank issues

[madcrafter52]

I have a 1987 GMC Wrangler (basically just a V2500) that originally came with a fuel injected 350. Somewhere along the line it got swapped with a carbureted 307. Whoever did the swap didn't really hook anything up except what was necessary and then called it a day, so i am dealing with a lot of random connecters and cut wires. My current task is setting up my fuel gauge and dual tank switch. The issue is that since this used to be fuel injected and have an ECM and such there is a lot of wiring I don't need anymore. I think i just need power and ground to my cab switch and i will be good to go but just wanted to confirm. I edited this wiring diagram to what i think i need, is this correct?

Do a search on dual tank wiring. I converted my 85 to 87 EFI dual tank.

Around pg. 203 are the dual tanks from the 87 wiring manual.
