I just recently purchased a 1992 Toyota SR5 and was looking under it today and there is a loose wire with two prong connector hanging off the front seems like its a notification wire that shows on the dash if I am in 4x4 mode. Does anybody know where that plugs into down there in the front end? THanks

 

Picture would probably lead to less speculation on what it might be.

 

Very true. One place to look though would be right on the front of the differential. Is it hanging down under the truck or just hanging in the engine compartment?
