Default looking to swap engine

I have a 1991 dodge dakota 3.9, and looking to swap the engine to a 1995 dakota 3.9 magnum. Do I have to use the wiring/computer for 1995, or could i use the 1991 wiring/computer?

Short answer, No. There were a lot of changes from 91 to 95.

I think you'll need wiring and comp. The 95 Mag will be multiport injection and the 91 is throttle body.

You'll also have to swap out the speedometer (the 1991 is mechanical; the 1995 is electronic), and quite possibly most of the interior wiring.

When you add the reduced power output of the 1991 V6, I have to ask "WHY???"

I'd get the 1995 rebuilt first, if at all possible.

Pick up the FSM for both the 1991 and the 1995; compare the two.

Sadly, there's not that much common in the wiring.

(Could be worse, could be a 1996; THAT was an almost complete rewiring job due to the switch to OBDII and the RE series of transmissions.)
