The problem is your 2003 Jeep Wrangler is running PCI PCM and from 1996 to 2001 the Cherokee used CCD PCM. So the computer are not compatible and I don't know if you could just take the motor from the Cherokee it would have to be 1999 to 2001 because they switched to a coil pack spark system vs the distributor on the 1996 to 1998 and run a 2003 TJ PCI PCM.

I'm wondering if it would be easier to find a wrecked 1999 to 2004 Jeep Grand Cherokee and pull the 4.0L out of it because they ran a PCI PCM. I would still recommend trying to find a 2003 Jeep Wrangler PCI PCM with what ever engine you decide to pull so you don't have any problems down the road.

Hope that helps...
