Swap 3400 to the Pontiac Grand Prix 88 2.8

[viper83]

Hi!
My name is Siarhei and i'm novice on this forum.
Sorry for the my english - it not so good as i want

I have a Pontiac Grand Prix SE auto with a 2.8 v6 engine.

This is the car photo before rebuild starting.



Now the car is under reconstruction, but the old 2.8 engine is really bad... So i plan to swap new engine into the Pontiac. I founded a 3400 engine with transmission from the 2000 Chevrolet Impala.

Refer to the Photo below:





The engine is in good condition, so i believe the Pontiac with this engine could be the good project.

As i can see from this thread somebody already did the same swap

But i cannot find the details of this process.

So maybe you can help me and say, what additional parts i need? Do i need a Impala harness and impala engine ECU? Is it possible to combine Pontiac harness with Impala engine ECU?

Thanks!

You can splice the harnesses together to get the desired results, but you'll need both pinouts. Sounds be able to find those easily.
