If you want to be able to hide all the wiring etc - you will need to be able to skillfully pull various connectors apart and trim the wires etc. You may need to split certain "runs" of wires out of a main harness in order to hide them.
None of it is rocket science - but it will require some special tools. These connectors (Weathercock and Metripack etc) have their own styles of "males and females" and you'll need a supply of them as well as the tools to disassemble the connectors and crimp on the connectors. Delphi and others make the tools you'll need.
There's plenty of videos on YouTube that will show you how to do these.
Buying a GM standalone system and hooking it up and getting everything to work could be done by a 5 year old.... it's when you're trying to make it LOOK nice by hiding things is when it take A LOT more work and some skill.
Ironworks (a vendor here) makes brackets to hold the ECU and makes that easy to mount...
You're going to have to plan out where you intend to mount that --- and where you're going thru the firewall etc. Sounds like you haven't done this before so you need to think about the order of things. You'll also need to be able to fab up a mount for the DBW pedal etc.

True...we have done a handful of GM "Connect and Cruise" harnesses and the relay box is HUGE. If it is an automatic they give you two controllers to stash AND as Greg says I end up pulling the harness apart to make everything land where I want. YES even the tune is not great. They can be and should be tuned. The drivability and power can be increased.
PSI harness pedal and computer work well for us and we LOVE the Holley kit. Harness is already wrapped nice and offers lots of ability to tune. - Chris
