The lt. blue is located in the harness coming from the drivers running board going under the drivers seat and it catches all other doors. Use both door trigger wires and diode isolate each.

I dont know if there is a diffrence but in Directechs it says to use a 555lw. And the tach wire is white or PURPLE / white at the ignition coil or ECM. The ECM is located under the left side of the dash to the left of the column.
