LM7 DBW help I have a 5.3 that I'm putting into a 48' Chevy pickup. I don't know what year the 5.3 is, or what it came out of, but it has the red/blue 411 ECU, full wire harness, and a DBW TB. It also has 862 heads if that's helpful in identifying.
If staying with DBW, how do I know which pedal assembly, TAC module, pedal position sensor, etc... I'll need?
Or, would a DBC conversion would be easier? I know a DBC wire harness is needed, but what else is involved, including changes to the ECU?
Any input is welcomed. I'm open to either DBW or DBC, whichever is easiest/cost effective.
Thanks.

My 2000 silverado is blue and red. Check the location of the knock sensors, mine is lm7 and knock sensor are on top of the motor under intake manifold. You can also check the head bolt lengths if you have 3 different size bolts then it's gen 3
