It also has the 7way already factory installed I'm hoping when I get the harness from Etrailer it will the prodigy P2 will work without any new wiring! It's supposed to plug and play? Not like the old Jeep I had to wire from. Scratch.
Yes, the brake wire is already in the OEM 7-way harness. With your Prodigy you'll need to order a GM specific pigtail. There is a terminal block on the firewall behind the parking brake lever. Remove the black plastic cover and you'll find an empty 4-pin receptacle where the Prodigy plugs in.
In your power distribution panel in the engine compartment you'll need to install a 30 amp fuse in either terminal 1 or 2.....I don't remember which. Look in your manual, but that is the circuit that will provide 12V power to the brake controller.
The Class IV receiver I linked to shouldn't require any drilling in the frame. There should already be factory weld nuts in the frame and you only remove the OEM receiver then bolt the new one in place.
Wheel hub assemblies and knock sensors are very common issues for these vehicles. Also, have you serviced the transmission? A new filter and fluid is a good idea before towing that heavy. DO NOT do a chemical power flush, just a refill after installing the filter is all that's needed.
On the transmission subject.....IT IS A ROYAL PAIN IN THE NECK TO REMOVE THE FILTER PAN. In GM's infinite wisdom they ran the exhaust crossover pipe right in the way and you can't get the pan off unless you remove the pipe. Also, the tranny pan comes with a drain plug and you can try to get it loose, but 90% of the time you'll strip the bolt head. These bolts seem to fuse to the pan and GM made the hex part of the head really shallow so when you try to torque it off your socket slips and strips it. I have a friend that is an excellent mechanic but had not tackled a GM 1500 transmission service. He told me another friend asked him to work on his '03 Chevy 1500 pickup. When I told him what it involved he laughed and told me there was no way it could be that hard. Well.....the next day he called me as he ate a huge plate of crow; the exhaust had to come down and the drain plug stripped.
