what can i remove from the OEM engine harness? standalone Holley ECU GEN V LT4
man.. i havent started a new thread here in YEARS lol.
I am trying to button up a GEN V LT4 swap into my 2005 Z, and I'm retaining all levels of creature comfort, ie A/C, all BCMs, ABS, wheel speed sensors etc.
I have the factory engine harness stripped out and cleaned of all sheathing and covering, cleaned up and ready to pin out.. what im wondering is if anyone has the pin out available so i know what to remove and what to keep.
Ill be running a Holley Term X max for Gen v ecu, and will be wiring up my own AC system most likely, but still need to keep Horn, grounds and shared power, etc etc.
Id also be happy to send it to someone and have it stripped for me, im low on time. thanks.

for anyone who discovers this in search years later when human kind has been buried under sand for centuries.. the answer is
stuff left inside car= everything but the ecu.
All BCMs and wiring stays put, just unplug the ecu and throw in nearest trash can.
Answer for wires in the bay and orig harness?
The entire engine harness is useless save for one wire and plug.
Strip the thick black and yellow starter solenoid wire out of the harness and leave it plugged in near the battery in the three plugs tree.. use ot for your new starter.. thats it.
