Micro Switch

[FasTruckMonkey]

I found a micro switch mounted behind the go pedal..looks like one you would use for a nitrous kit for the full throttle switch. However this one engages right off idle..
I'm going to go back under there after work today to see if the previous owner left any wires attached to it.

What do you guys think? Propane or Nitrous? Something else?

I think the guy did a lot of towing with this truck..but I'm just guessing. I found a trailer harness cut underneath the dash also.

I'm finding all sorts of neat little things here and there.

Thats probobly your throttle sensor not sure if thats the correct term. The throttle is electrical no linkages sends an electrical signal to the puter.
