Phantom wire... Need Help!

[macmanmcy1]

I have a 99 Tahoe with a recent motor swap from previous owner. As I am going through the motor tightening loose bolts and what not I notice An unplugged wire wrapped around part of the frame. I don't throw any codes and the only problem I have with the engine is at speed it will hesitate for a split second a few times a day.. Any help with that would be nice also.. Tag on wire reads 3216... Thanks for the help

Do you have autotrac? i have a 97, but that looks like a plug that goes on the transfer case on mine...

Maybe the plug for the actuator on the front diff? Just a guess, looks like it has enough length to it and I can't think of anything else with a 5 pin terminal

do u still have ur air pollution pump ?

It is possible that the plug would have something to do with the old four wheel drive. My truck has been converted into a 2 wheel drive and bagged. Not sure about the pump... I don't think I have it. Do you know where the pump should be?
