6port Fuel Selector Switch Plug Wire Diagram... AHH HELP :D

I just got this truck its an 86 F250 XLT LARIOT and its got some fuel delivery problems.... Basicly the 6 port fuel tank selector switch has been horribly messed up...

its got a plug on it with i think 6-7 wire holes but

only 4 black wires coming off of the plug,
2 are spliced into 2 wires in the main bundle traveling along the frame....
2 are stripped and hanging loose near by 2 Stripped and loose wires coming of the frame.

I need to rewire this selector switch correctly and i spend 2 hours searching the forums for a diagram and have not found one.... if there is a diagram section i must have missed it... also cant find any detailed info in my hayes book

IF ANYBODY can help THANK YOU!!

-Nathan

Does your truck have a 460? If so, look in the 86 diagrams in the Haynes, and keep an eye out for a page that says "hot fuel handling". If you have a 460, then that should be the correct diagram.

Look around the engine compartment for a emissions sticker. If it says 5.0, it's a 302. If it says 7.5, and the engine is huge, then it's a 460.
