yes it is located rear of the under of the vehicle rear of the fuel tank and the connector should look like this picture

Expert:  Gary replied 1 year ago.

key ON the red/white and the pink wires should be 12 volts and the black a good ground and when cranking it over the dark green / white should show 12 volts when cranking it over

if those all check out and the wiring looks good the module is bad

and when replaced the new module MUST be programmed with a programming scan tool to install the correct programming into it or the new one will NOT work
