I'm new to the group. I have a 1991 dodge Dakota with a 3.9L 6 cylinder. Got it used from a friend of mine. Now I just got a 1990 Dodge Dakota same engine. What parts am I able to transfer? The interior matches, but engine wise and fuel system wise. I'm asking to transfer some of the newer parts I've installed on the 91. Thank you for any information.

 

Same engine, same fuel system, same transmission, axles and hubs are different, front clip varies from the core support forward.

Anything that bolts to the core support changes. The 91 also was the last of the TBI years.

Reason I was asking is because I noticed the fuel tank on the 90 was different than the tank on the 91. Is there a good place to find wiring schematics for the drivers side under dash area. I've had to rewire the under hood area and a little under the dash. Yet their is 3 wires that's still hanging that I havent a clue where they go.

 

Yes there is; from the factory service manual for both the 1990 and the 1991.

Yes, the fuel tank changed for 1991; the pump's still available for it, unlike the 1990, so I'd swap to that one if possible.
