Just purchased a 2014 L96 replacement engine for my 2007 Tahoe. Will I be able to use my factory L59 harness or do I need to use the L96 harness?
Also, are there any other other obstacles that I should be aware of, or is it plug and play?
I have the L96 Ecu if needed, and both engines are ff/vvt.
Any helpful advise regarding this swap would be greatly appreciated, thanks you

If its a Gen IV (which it is ), its should be all plug and play. Tune and go.

Thanks tig!​​​

I actually posted for a friend. However, would we be better to buy hp tuners and swap the tunes over from the stock ecu or just pay someone to do it? I need to buy hp tuners anyways for my trans am, just don't know much about the credits.

Any time street I'm planning on doing the same thing to my 07 Tahoe.

Gatcha. If you're getting HP Tuners anyway, why waste your money to pay for someone else to tune it, silly.
I'm actually not sure about the credits, I know nothing about tuning. I wish I did, haha.
