Hi,
I would not bother to run the ground wire all the way to the battery. Just make sure that you are attaching the screw to a good and well grounded surface. Not something like a metal strip attached to the plastic dash, and nothing else.
Did they say what size wire to run? #10 wire is what I would use, because two axle brakes can use 5.5 amps per tire at 14 volts, (panic braking). If using #12 wire, then the voltage drop across all that wire length will limit the amperage due to resistance in the wire, and you might only get a maximum of say 9 volts back to the brakes. ..
Good luck,
Fred.
