2nd Gen Non-Engine/Transmission Fuel Pre-heater Wires.

[MHalloran]

HELP! The two wires feeding the fuel pre-heater became disconnected. Does it matter how I re-connect them back? They are male/female connectors and I noticed one wire is heavier (fatter) than the other. Don't wanna burn it up. THANKS FOR INPUT!

I checked my service manual and found that my 2001 has a large locking plug that will only go on one way. There is also a detailed description of when and why the heater works. ( This is helpful for those wanting to disconnect it!) If you will fill in your signature, I'm sure someone with the same year truck will answer your question.

Dennis, yes, I'm now in e-mail contact with Mike Halloran. Nick.
