Question:
Do you have a custom wiring adaptor to work in a 2018 Colorado with trailer package to work with Hayes # HA81760

Your 2018 Chevy Colorado has the brake controller wiring ran under the dash of the truck but there isn't an adapter that uses a connector. Reason being there's only 4 blunt cut wires under your vehicle dash for the brake controller wiring and not a connector of any type. To install the Hayes controller part # HA81760 you need the Hayes universal connector part # HA81789-HBC to run to those wires.
I attached an install video that shows a similar brake controller installed in a 2018 Chevy Colorado for you to check out. It will show the entire process and where to find the wires etc. The panel is right behind the emergency brake pedal.
