where on a 1986 302,f150 ,4x4 is the fuel pump relay switch and the inerta switch?

 

Relay is mounted around the master cylinder area, and the inertia switch would be above the brake pedal on the firewall. Or should be, it is on the '87-'91's. Haven't owned a 85 or '86 EFI truck.

okay,now where is the eec switch located?also,the fuel pump relay switch has a white wire with a black stripe that goes down to the frame,whats it for?

 

I take it you are calling the relays switchs.
That being the EEC power relay (brown) is right beside the fuel pump relay (green).That wire is more than likely faded and it is a PNK-BLK wire and it goes to the inertia switch.
