Gently slide the panel out of the dash. The white plug with the red circle around it is the one that will be modified. I found it easier to work on it when it was removed from the panel. There is a little clip on the plug....depress it and you can pull the plug ot of the panel.
While there are a couple of different jumper combinations that one can use. My friend wanted to turn his lockers on at any time. To do so, pin 1 (ground) is jumpered to pins 4 and 5 (locker enable signal 1 and 2). Some folks add an extra switch and route the ground wire through it. This allows them to turn the bypass feature on and off as needed. My friend opted to skip the switch as he has no desire to "lock" the bypass in or out by using an extra switch.
Pin 1, the ground connection, has a black wire connected to it. Pin 4 is next to Pin 1 in the other row. Pin 5 is right next to pin 4.
We used a wire tap to make the connection for the bypass. A piece of 16 gauge wire (the yellow wire in the above pic) was first connected to the black wire (Pin 1).
From pin 1, the yellow wire was tapped onto pin 4 (the red/white wire) and then to pin 5 (the violet/dark green wire).
Once you have the three wires connected together, you are done. If you removed the plug from the back of the panel, reconnect it. Put the panel back into the dash and reinstall the cover over the dash section. You are done!
Good trails and remember to TREADLightly!
I helped another friend do this same modification today. Pin 1, the ground wire, was black. The other two pins were NOT the same colors as I mentioned in my write-up. Obviously, DC has changed the wiring colors over time. The good news is that we ignored the wire colors and connected the pins based on pin number....and it functioned the same as the one I previously modified.
