'04 LQ4 from van and harness/ecm from '02 truck. Any issues?
Hey everyone...
I found a nice deal on a complete low mileage LQ4 from an '04 van, but I guess the harness was screwed up in the wreck. I am thinking about having the yard give me an ECM/Harness from an '02 Silverado with an LQ4.
This is going into my 81 Malibu with a T56. I am planning on re-working the harness myself and tuning probably with HPTuners. I plan on going with a cable driven TB/Intake, so that wont be an issue.
Anyone see any issues with using the '02 harness/ecm with this '04 motor instead?
Thanks.

You may run in to electronic throttle body controls vs. cable by switching up.
Just make sure that the harness you get is for the same kind of TB as your engine, either cable or ETC.

Thanks for the reply. Righto about the TB. I am planning to switch to a drive by cable now anyway, so im not expecting issues there.
Anyone else think of anything I might be overlooking?

How light is the Malibu, best I can remmeber those cars aren't that big. Should weight less than my Nova I would think? Anyway good luck man and get us some pics of the swap whenever you get the ball rollin.

Cool, thanks for the replies guys.
70Nova,
