Adapter https://www.ebay.com/itm/254353420216?mk...media=COPY this kit works best in case you run into a truck that has lost a terminating resistor as the three pin weather pack connection has a terminating resistor built in so it can be used to test other things on the truck until the trucks terminating resistor is fixed. Just remember that when working on truck with a lost terminating resistor the extension for the three-pin weather pack connection is what has the terminating resistor it's not in the first section of the connection that can be used everything is good
