MJ 97+ cab wiring harness

[dlucas2]

To all my fell MJ’s who have done the complete swap , can anyone take my harness and remove the unneeded stuff and get it ready for me to install. 

 

Unfortunately I don’t have the time or confidence to mess with the wiring. Willing to pay for the expertise, if anyone can help please let me know.

As much as I love a clean wiring harness, You don't necessarily have to remove anything.  About the only thing you'd remove is the rear wiper fluid hose and wiring for the rear defrost and wipers, everything else is used after the swap.  I just used the entire harness since there is plenty of space and it wasn't worth my time to separate.  These aren't racecars so the extra pound of wiring won't hurt anything.

Much appreciated, I’ve been scratching my head on this one. From working on my sons cherokee same year as my donor harness, i’ve got the gate , third brake light , lock , wiper motor. Roof , speakers , rear interior light and it seems there is a provision for the factory tow hitch in the left side of harness. Ideally i’d like to get rid of the unnecessary stuff and reuse the third brake light for suck . the interior light for the bed lights and find a factory tow harness to use

there's a guy in the vendor's section of the classifieds making plug=n=play trailer harnesses.

There is a bracket in the rear with plugs for everything in the rear of the XJ and it's all separate harnesses, I'll call it a plug block because idk what it's actually called.  The wiring is there in the main body harness but it stops at the end of the main harness in this plug block, everything branches from there on separate harnesses to the third brake light, speakers, ect.

 

I just mounted that plug block to the rear wall of the MJ and only used the taillight and fuel pump wiring harnesses.  I extended the XJ taillight harness and adapted the fuel pump harness for the Dakota pump.  All that other harnesses you can just leave in the XJ.  I kept the plug block and wiring in the main body harness because as I stated there wasn't a reason to strip it, but also the rear wiper/defrost switches can be used to control whatever I wanted to plug into the plugs in that plug block.
