Nice, thx. What are you guys doing to that harness? I'm surprised they're using the touchscreen deal(radio) for the ppv's.
As said above, GM includes a harness in the cargo space AND console area (the cargo space harness is new for 2021) which allows us to access direct feeds from the battery, ignition, brakes, transmission park, vehicle speed, door triggers, and wires that GM pre runs to add lights and siren speakers. Just recently GM has nixxed the 6J3 option which adds wires in the grille for lights and a siren speaker.
The best part is is that GM is offering a ton of pre-ran wires as standard, meanwhile to achieve the same amount in a Ford Police Interceptor Utility (Explorer), you'd have to order multiple options costing nearly an additional $1000.
They're utilizing a smaller version of the touchscreen available in the civilian models. It's something people who use Tahoes love, blows the radio screen in the FPIU out of the water.
