Guys, being a little bit anal retentive, I wanted to use the body junction block on my LB7 (2001) to power some gauges and accessories. I got the idea after installing my trailer brake controller and noticed several unused connections there.

I searched quite a bit to be able to find the 6 way connector that matches the one used on the trailer wiring harness. Many of the aftermarket SEOs use these connections.

Finally I found them on the Mouser.com website. Here are the part numbers.

12193930 - connector
12193931 - locking pin
15324339 - terminals

Note that the terminal listed above is for about 14-18 gauge wire. Other terminals are available for larger wires and the connections are good for 30 amps I believe.

Hope this helps someone who wants to either build their own trailer brake controller or use one of the other connections to power accessories.

Well additional info. Those part numbers are for the connector in position C4, which is just above C5, the trailer brake controller harness. The C4 has constant battery, ignition voltage and ground .
