If you lay on your elbows and look at the fuse box the little dia. port is right there. The number 1 pin is the top left corner then there is a blank under it. The plug on the radio has the female slots on it but its two pins to short because the alignment slots on the plug when you plug it in will only get 10 and 12 but not number one. So with a small screwdriver you can lift the anti fall out tab up and push the pin out then just move it down one and re pin it. Then with the radio plug remove all the wires except the top left (#1 data), lower right (#12 gnd) and the pin that is 2 spaces above the lower right (#10 GND). That is if you look at the back of it like it was plugged in with the alignment slot deals to the left.
Then if you need a power supply 12 volt you can run a wire from inside the fuse box and then out and around the back side of the diagnostic port plug and pin one of the extra wires from a mitsubishi plug. Which will be a male pin for the diagnostic.
The reason I discovered this is because I just got about 60% of my garage cleaned out and found all kinds of stuff and me being a pack rat I now have a drawer full of nothing but electric plugs from cars. It comes in handy sometimes.
I hope I didn't explain this like I think everyone is on a 5th grade level but I just try to make stuff as clear as I can to help everyone out and sometimes I'm not the clearest in the world. As usual I need to take pictures I guess. If anyone needs photos just yell and I'll post them.
