*Pin 3 on XJ C118 connects to pin 5 on XJ C119. This will provide proper wiring for the brake lights I think this is the fix to my issue. Edit: confirmed. Jumping those two pins together makes the brake lights function.

Yes, it is switched power for brake lights. My confusion is that there is no dedicated brake light or 'stop' wire on the MJ. Just a LH turn/stop and a RH turn/stop. The XJ harness has LH turn, RH turn, and the separate stop wire (blue/white). I'm unsure of what to connect the blue/white wire to.

Using this thread, can anyone tell me how to wire the renix XJ harness to the MJ harness that will make the brake lights work? Turn signals work when connecting them bit the light blue/black wire from the XJ harness is not connected to anything and I don't understand how to connect it to the MJ harness. Thanks in advance. Edit: it looks like I glossed over this section "Pin 11 on XJ Black connector, need to run a wire to pin P on the turn signal/hazard switch.(11 pin flat connector on lower steering column) This will provide proper wiring for the brake lights" Makes sense, I just need to figure out the easiest place to tap into this. Second edit: the above quote is pertaining to the HO harness, the renix XJ harness does not have an 11th pin, but I believe I can achieve the same result by connecting the light blue/black wire to the hazard switch circuit.

New coolant sensor fixed the gauge issue. New PS pump and lines did not fix the whining. New pump whines just as much. I replace the high pressure line. Inspected the return line and vacuum bled the system. There appears to be no air bubbles in the reservoir and no fluid loss. Could the steering box be the cause of this issue? PS reservoir hit 210°

My Wrangler went down so it's time to get this project buttoned up. I finally sorted out the brakes so it was time for a test drive. About 10 minutes in the power steering pump was screaming. I pulled over and checked the temp of the fluid reservoir... 380°! Fluid was full and no air bumbles in the reservoir. After that cooled down I limped it home. In the process my coolant temp gauge spiked almost to the red about a block from my house. I *think* the original cluster in the donor vehicle had dummy lights, so I may need to swap out a sensor to get my gauges to work correctly. I checked the temp on a few things and the thermostat housing was 202°, passenger side of radiator was 178°, driver side was 139°. E fan never came on. I'll pick up the sensor today, as well as new a new power steering pump and hoses. Hopefully that will get these problems sorted out and I'll be on the road!

^ for some reason I can not remove the above from my post. Little guy is obsessed with the Comanche now.

Wow, I wish I was closer. That front axle would be perfect for my swap!

Does anyone know if my 86 or 89 master is compatible with a 95/96 booster? I'm struggling with search results.

Thanks for the link, and info... I'll keep an eye out on there. She's moving on her own. I rebuilt the drum brakes because the last person to do a brake job on it assembled them incorrectly and caused some damage to the drums, the shoes were also soaked with fluid. I have no rear brakes, or just rear brakes. No in-between no matter how much I adjust the rod on the load sensing valve. And yes, I bled the brakes following the proper procedure. Today I swapped out the prop valve for the one in the XJ. I'm going to pick up an inverted flare coupler tomorrow and delete the valve at the rear. I'll reuse one of the factory hard lines, they are in good shape. My goal is to drive it to work before EOW

Thanks for the comments guys. I cracked open the rear diff this morning. 37 9 on the ring gear, so 4.11s. I'm happy to have a little deeper gearing but now this means that my truck will be staying 2wd for awhile. I'm not going to dump money into regearing the 30 I have and I doubt I'll come across a factory 4.10 axle. Maybe I should sell my built wrangler and start looking for tons? Haha.

She's up and running! Progress was slow the last week and a half but I finally got there. Interior is in the truck (Need to clean some things still). I picked up the driveshaft from the drive line shop yesterday. I need to change the rear diff fluid/figure out the ratio. If it's 3.55 I'll stick the dana 30 from the Cherokee in. Then I just have to get the brakes sorted, tires on, and I'll be on the road!

I haven't made much progress in the last few days. I cleaned all of the interior plastics and installed the dash. I dropped the rear driveshaft off to be shortened. I need to splice the XJ harness into the MJ rear/interior harness and then I can test start it. It's going to be 2 weeks before I have my driveshaft, so I should have everything buttoned up by the time I have that. The issue with my wobbly steering wheel was that I installed the spring before the collar that pressed against the bearing race, so the race did not have tension on it, allowing some play.

Thank you! That explains why I didn't label it, it wasn't ever plugged into anything.

Under hood is buttoned up minus 1 vac line. I installed the dash today but I'm not sure what this plug goes to. The other plug in the picture (with blue tape) is the plug for the glove box. The unidentified plug has a short (14") wire connecting it to the glove box plug. Any ideas? For anyone wondering, I'm 59 hours into this project, including stripping down the XJ and the MJ.

Thank you! Donor xj does have this, I'll swap it over.
