Hello!
I am slightly confused about how a specific OS affects an ECU.
More specifically, I have an 08 Colorado with a 2.9 I4, 4L60e 4x4 and an E67 ECM. Recently a good friend of mine sold me a 4.8 Vortec out of an 08 Silverado with the intent of doing an engine swap.
Obviously im missing some wires for some injectors and spark plugs, so Ill need a new harness.
From what I understand, the E67 can be flashed with a number of OS (Trailblazer SS, CTS-V, etc). If I am going to have a harness made, will the configuation of the pins depend on the OS I intend to flash on to the ECM?
I know this is probably a basic question but its a question Im losing sleep over (its 2:27 AM).
I do intend to use HPTuners myself as I have a decent knowledge already of how to tune and will (probably) do a turbo setup later on down the road. I'm just not sure about the wiring dependancies.
I know this is a tuning forum but hey, some of you might know since Google is failing me constantly...
Thanks in advance.
