Trying to track down an electrical bug and am trying to find out where the main bus is the 12v key-on ignition source among other things. Pretty much where all the key-on power comes from for the fuel pumps, gauge cluster lighting, side mirrors... pretty sporadic list I know, but it seems all these things are related.

Thanks.

Hi Matt,
Fuel pump diagrams posted here. If you need others, PM me and I'll see what I can get for you.

Thanks bro.

Also, if there is a common ground to those circuits. Talking with a friend a little while ago, I may just have a poor ground connection, but for it to be affecting so many things, I believe it would be a larger ground plane.

The battery is at advanced auto getting re-charged (since the truck sat for so long without running) but will start doing voltage drop tests on all the grounds tomorrow or Sunday.

Any and all help is appreciated.
