Search gives me no details on the factory towing package, neither does the Toyota brochure or handbook. I'm wondering if my 2003 100-series has trailer brakes as the electrical trailer out put is a 7-pin which is usually on used with a trailer brake and all the 7 wires seem to come from the factory harness.
I know I can test the outs with the meter but interested to know just what the factory "towing package" contains.
