6.0 swap wiring/ computer
Yes I've searched but not finding much about DBC 6.0/4l80 swap.
I'm swapping a 6.0 w\ a tbss and 90mm TB, 4l80, into an 01 tahoe. So I figured the easiest route was to put a DBC TB. However, the motor and tranny comes out of and 05 2500HD which is DBW.
Will the 2500 Harness and ECM work with the DBC TB, or can I use the 5.3 Harness modify it and 5.3 ECM with a reflash to run the 4L80. I have both harnesses and both ecms.

thanks but I have the harnesses for a 2500 6.0\4l80 and 5.3\4/60.
I think the easiest is going to be re-wiring the 5.3\4/60 harness
But I'm still not clear on the computer. I believe the computer for the 5.3/4/60 will run the 4/80 but not sure.

The 5.3L drive by cable harness can be re-wired to run the 4l80E. You will have to change the the parameters within the ECU for the larger engine, larger TB, and transmission swap. You will also need a larger aftermarket TB that will bolt up to the TBSS intake.
The 05 6.0 harness can be used with a 1MB PCM and a DBC TB but you will need the correct calibration to run a cable throttle body. You will also have to rewire for the cable throttle body connectors since they are different from the DBW connector.
Either way you will have to Re flash the ECU for the larger throtle body.
CalEditor is very knowledgeable on PCM calibrations. I am sure he can help you get what you need for your swap.
