the best upgrade I did to the braking system on our tt was wiring

I also added a 10 ga ground wire from the truck's 7 pin to the truck battery. I eliminated all crimpon connectors, put new twistons where needed etc etc.
brake circuit amp draw went from 4 or 5 amps to 12 amps, normal for 4-7 inch brakes
its ok to check the resistance and voltage in the brake circuit, but the real indicator of electrical performance is the amps used
