Dadinator Posted March 7, 2011 Share Posted March 7, 2011 Greetings. I'm working on converting the MJ over from Auto to Manual. In addition, I've had to replace the steering column. Once I got the steering column moved, I connected the wiring back to it. I have some stuff still not connected. Pay particular attention to the stuff I circled. I know the big white button thing is the switch for the auto/brake start circuit. Can I just cut that out and connect the wires together? Pay no attention to the red/green blob of wires. That is aftermarket stuff that I've got to redo. Anyone have some wiring diagrams or pictures they want to share? Any Ideas what this stuff is for? Thanks in advance.

jimoshel Posted March 7, 2011 Share Posted March 7, 2011 The long white thing(switch) is the stop light sw. Mounts by the brake pedal. Link to comment Share on other sites More sharing options...
64 Cheyenne Posted March 7, 2011 Share Posted March 7, 2011 XJs and MJs have a lot of "extra" plugs, that is why a lot of things like intermittent wipers are so easy to install. I would do a function check see what don't work like ? Under my MJs dash probably got at least 3 or 4 plugs that go nowhere. Link to comment Share on other sites More sharing options...
jimoshel Posted March 7, 2011 Share Posted March 7, 2011 One day out of curiosity I took one of the unused plugs from under the dash and stuck it out the window facing forward. I picked up 8mph on the top end and gained 3mpg on mileage. I figure it was the wind pressure pushing electrons thru the wire faster. Link to comment Share on other sites More sharing options...
Gjeep Posted March 8, 2011 Share Posted March 8, 2011 Far left is for headlight delay/sentinel module...when you turn headlights off this module keeps them on for 30 seconds (or so) Smaller plug in the center is for crusie control servo underhood.

Both of Gjeep's comments are correct, and the white plunger device installs in the brake pedal housing (there is a hole for it. It is a vaccum switch that shuts off the cruise control when you press on the brake. There should be a black hose (approx) 1/4" in diameter) somewhere under the dash that plugs into it on the left of the plunger. Link to comment Share on other sites More sharing options...
Dadinator Posted March 8, 2011 Author Share Posted March 8, 2011 Thanks. Any pics or wiring diagrams showing where they should hook? The white cruise control thing already has the hose connected. Link to comment Share on other sites More sharing options...
JeepcoMJ Posted March 8, 2011 Share Posted March 8, 2011 gjeep is 100% correct. no diagrams on my end, but they're fairly self-explanitory. and you don't need any of them to drive it, they will not effect your driving at all (if you remove white switch, plug hose) Link to comment Share on other sites More sharing options...
