702_MJ Posted December 7, 2012 Share Posted December 7, 2012 So ever since my dad gave me my truck, 86' MJ, I always had a tail light issue. When you turn the passenger signal on and step the brake the signal stops and the brake light takes over if that makes sense, and I notice it doesn't light up the drivers side when doing that. After some interrogating I found out my dad had to cut and splice wires when he swapped in a 92' XJ dash. Today I was sperlunking around and found those said splices. And he has the brake switch running to the passenger tail light. But there's only 4 wires on the MJ harness and like 5 on the XJ....any way my question is how is the brake light wire ran stock? I want these things to work normally.... Btw I have an owners manual for the XJs...but seems MJ wiring is completely different. Thanks in advance for any help.

You have to route the brake light switch wire through your Turn/ Hazard switch. If you still have the old steering wheel column, its Pin P on the 11 pin flat connector on the lower column. The Xj's have a seperate bulb for brake & turn, The Mj has it combined. Link to comment Share on other sites More sharing options...
702_MJ Posted December 7, 2012 Author Share Posted December 7, 2012 Thanks, makes my job so much easier. So can just piggy back it off pin P wire? Link to comment Share on other sites More sharing options...

702_MJ Posted December 7, 2012 Author Share Posted December 7, 2012 Actually I just looked and I have a white wire in that pin, on the turn/hazard side. Link to comment Share on other sites More sharing options...
