How do you hook up trailer wiring on a pontiac montana?
I bought a wiring harness at a store specializing in all things trailers for my 2000 Montana (they are also readily available on-line). The instructions were so-so, but what you need to find is the place behind the cover in driver side trunck. On mine, there was a plug to accept the wiring harness. After that it just about routing the wiring – I routed mine through the rubber grommet where the brake light goes.
