Kona Posted October 31, 2012 Share Posted October 31, 2012 There is a plug by the dip stick next to the 2 big plugs that is a single plug, 1 prone, where this go to?? Obviously is unplugged and can't find the other end to where the heck it goes to? Wonder if my TCU is not working because this plug? Link to comment Share on other sites More sharing options...

HOrnbrod Posted October 31, 2012 Share Posted October 31, 2012 Probably for the underhood light. Why don't you edit your signature to include the year and model of your MJ? Link to comment Share on other sites More sharing options...

cruiser54 Posted October 31, 2012 Share Posted October 31, 2012 Has nothing to do with the TCU. The only wires anywhere near there that have anything to do with the TCU are in the big plugs near the trans dipstick tube or they're the ground wires at the engine dipstick tube stud.

ParadiseMJ Posted October 31, 2012 Share Posted October 31, 2012 What color wire? I have an extra wire too...black w/red tracer and a single prong connector. It isn't my underhood light. Comes out of the TCU harness. Link to comment Share on other sites More sharing options...
