Cruise Control with Drive By Wire for Swap
From looking at the wire diagrams I have found for 02-04 LQ9's with DBW, it appears that the TAC module and ECU handle the cruise control logic, and you just wire in the cruise switches to the TAC module.
Is it that simple or is there more involved?
Would love to have cruise on my swap, and leaning towards keeping the DBW setup if I can get it. If not, then I might consider swapping it out for a cable throttle body.

My car will be on the road in a week or two, so i will know how it works then.

I agree, it really is that simple. All the functionality is built into the TAC and PCM. What you need is a set of switches: 1) A rocker-type switch that will stay on when you turn it on and stay off when you turn it off, 2) a momentary switch for resume/accelerate, and 3) a momentary switch for set/coast. These are the standard GM controls found on all of their vehicles through the 2000's and I am sure other years.
Oh year, you also need to hook up a switch to the brake pedal. The brake pedal circuit will also need a resistor - you can search the forum for more details on that. It's been a while since I wired mine, and I forget exactly where the resistor goes.

Does this mean it is even easier for gen 4 setups without TAC modules? My harness already is hooked up to the brake switch and controls brake lights, uses a 2009 E38 pcm and tcm for the LY6 and 4L80e set up.

Don't think so. It's most likley going to be harder if not impossible, because the cruise functions on Gen4's like yours are run through the BCM. I've seen threads on it before but cannot find them now.

THis thread touches on what all the BCM does. https://ls1tech.com/forums/conversio...e-e38-pcm.html But then I realized you posted in it already.
