CS-17 Posted March 2, 2011 Share Posted March 2, 2011 My dad found this do-hicky in the front bumper pan (my front bumper is built as the frame and pan that holds a 9,000 pound Mile Marker wench :D ) of my newly bought MJ. We didn't find any places it seems to hook to in either the engine or the wench, and have no idea what it is, so we thought we'd see if any of you guys had a clue what it is. It has the two electrical hook-ups that lead to a spring-loaded switch(?). Quote Link to comment Share on other sites More sharing options...
jimoshel Posted March 2, 2011 Share Posted March 2, 2011 I would take a wild guess and say winch control. The parallel connector hooks to the relay center and the square one is tied in to the MJ wiring. Don't think the metal thing is original. Looks like something added when the original switch got busted or lost. Quote Link to comment Share on other sites More sharing options...
jons87mj Posted March 2, 2011 Share Posted March 2, 2011 i would think that went to your throttle body i seen one like that on mine Quote Link to comment Share on other sites More sharing options...
Boots Posted March 2, 2011 Share Posted March 2, 2011 That is the TPS (throttle positioning sensor) for an mj with an auto transmission. It's supposed to be on the throttle body. Quote Link to comment Share on other sites More sharing options...
WBKrazy Posted March 2, 2011 Share Posted March 2, 2011 ah yes, that is the extremely rare and hard to find BPS (bumper position sensor)... just kidding, it is a TPS.... someone probably dropped that down there after they replaced it Quote Link to comment Share on other sites More sharing options...

You have solved my problem and won the prize (you'll have to buy something for yourself :D ). My MJ used to have an automatic transmission in it years ago (the people who owned it before me changed it), so this must be a leftover from then. Thanks guys! :clapping: Quote Link to comment Share on other sites More sharing options...
