Why go after market it 's already there just have to wire it up and controller for the throttle. Goto to a junk yard and pull the controller and then vacuum reservoir. Then do some wiring You might have to use button or switches on the dash to control the ECM.
A 89 yj with a 4.0 aw4 sye out of an 92xj. Now the hard part is done time to get it up in the air just a bit. Working on 8.8 with 3.73 and lsd for the rear. and new D30 hp with 3.73 .
