can anyone tell me what the three wires on the side and back of my pump are for and what would happen if they came unplugged.

 

One is the shut off valve. If you undo it the truck wont shut off. One is the KSB switch, it advances the timing when the truck is cold. And one is... Dang I'll have to go look...

I can get you a picture up in a little while...

 

alright if you can get that pic that would be great. thanks

 

Non-Intercooled Wires








A: Grid heater ground
B: Air temp sensor
C: Engine ground
D: Grid heater power
E: Oil pressure sender
F: Water in fuel (WIF) light sensor
G: Shutoff solenoid
H: KSB solenoid
I: Main bulkhead connector
J: Low vacuum warning sensor
K: Starter relay
L & M: Grid heater relays

The other wire on your pump should be the TPS
