SwayAwayComanche Posted September 10, 2011 Share Posted September 10, 2011 I'm to the trans swap in my ho build and hit a issue. I have a 99 aw4 out of my cherokee i would like to install in my comanche, the engine and T-case is also out of the 99 running 92 obd 1 wiring. The problem i have is with the 99 trans having the extra front sensor. If i was to swap the wiring harness and sensor's from the 92 aw4 trans to my 99 aw4 and just not plug anything into the front sensor, will the trans operate correctly? i appologize for for the long winded question. Thanks in advance for the help! Link to comment Share on other sites More sharing options...
JeepcoMJ Posted September 11, 2011 Share Posted September 11, 2011 Swap the nss, remove the harness connector from trans writing and swap pin for pin to the old connector. The extra sensor will be un used. Link to comment Share on other sites More sharing options...
SwayAwayComanche Posted September 11, 2011 Author Share Posted September 11, 2011 so if the harness is 100% swapped and nothing is plugged into the front sensor on the 99 trans it will still function properly? Sorry just not completely understanding. Link to comment Share on other sites More sharing options...
JeepcoMJ Posted September 11, 2011 Share Posted September 11, 2011 just swap the neutral safety switch, cut the connector that goes to the engine wiring off, and splice on the proper year connector. the connectors are wired the same, so getting it wired is very simple. you just won't use the two wires for that extra sensor. I say cut and splice because otherwise you've got to tear into the trans a bit to get the wiring installed in it. Link to comment Share on other sites More sharing options...
