i have a 2000 EXP and i tow an open style trailer with an ITB car on it and it towes just fine. my question is; the trailer i have has brakes and i was wondering how do i hook them up? it looks like under the EXP there has been an adapter of some type to convert the trucks wiring to a standard 4 wire plug and my trailer has the round plug for the brakes. i've opened the center console and it looks like there's some empty connectors to plug the brake box that i bought, is that possible? any help would great thank you.
