Just installed a trailer hitch from etrailer.com. now working on the wiring harness from tekonsha for the volvo.
Trying to figure out were you can go through the firewall with the wire th h as t has go make it to the battery of the car.
I originally checked my car out by volvo and the dealership wanted nearly $400 just for the wiring harness for the car, then 3 hours of labor.
I have done all the connections of the harness in the back of the car and the running of the wire up to the dash at this point. Need help to get through firewall to battery.
Thanks.
