A/C ecm wiring for idle

Have a 2003 L59 engine and ecm service# 12576106.

Looking to see who has wired in the a/c somehow to raise idle when the compressor kicks on so you dont have idle drop out.

I found some info on the ls1swap website and was wondering if the highlighted wires are the ones needed or if there is a simpler/1 wire way to do it.

Website shows another way where a 12v activation wire going to pin 17 but does not make it clear if this can be used alone of if I would still need the 5v references.

Just hoping someone has dealt with this and has some info.
