I found something last night when I happen to take my seat off and look at the wires and power commanderstuff under the seat. Well I was just curius to see whats there. I saw this plug that comes out the side of the wire harness that is connected to the ECU. Amongst the multi wires that comes out the black ECU box and goes into the multi coil there is this one wire with a plug on the end of it just hanging there. Dose it go anywhere. Did it maybe fall out of its connector. I can’t see anything that looks like it would connect but, why is it just hanging there what dose it do.

the wire actually comes out at the same spot that the wires come from to the ECU. meaning that it looks like an actual part of the harness like afactory job. It's to neat a job to be done after woods to me. could it be some diagnostic thing maybe?

I just took my entire wiring harness off and put it back on and didn't see any plugs that looked like that.

I have never seen a PowerCommander serial port model but if you have a Power commander that would be my guess.Mine is the USB and the wire for computer comes off
