What wiring harness would I need to convert the stock 4-pin connector to a 7-pin round connector (for assisted braking)? I was looking at the OEM one here, but I'm not sure if this will provide the connections in the cab for the brake controller. Anyone know if it will? Is there one already there from the factory? Haven't even taken a look yet actually. Is there a better/cheaper one out there?

Thanks for the help.

I bought the OEM 7 pin harnes and it came with the blue wire for the electric brake controller. The harness cost me around $70. I would go with the OEM one versus a cheaper aftermarket one. The OEM one is easy to install and uses the existing connectors and mounting locations on your truck.

 

Cool, I'll pick it up. Thanks.
