4.0L into an 88 YJ

[oklahoma88]

I recently destroyed the old 4.2L in my YJ. i picked up a wrecked 96 XJ Sport and i want to swap the motor into my YJ. Aside from the basic bolt up i have no idea as to how to wire up the harnesses or even the OBD2. If anyone has done this or could point me in the right direction that'd be appreciated!

Thanks,
