PLEASE NOTE: If you do not find a suitable wiring diagram for either the SMT6 or SMT7, it means we do not have the diagram as it is impossible to have a wiring diagram for every vehicle make and model worldwide. We can create a wiring diagram for you, but you will need to send us your specific vehicle's ECU pin out data. If you do not have your vehicle's ECU pin out data, you can search the Internet for a suitable source. You can also contact the vehicle manufacturer. Alternatively, if you know how to use a Voltmeter, you could measure the voltage on the pins/wires of the ECU to determine their function.

Both the SMT6 and SMT7 wiring diagrams have the same look and functionality.
Step1: Select the Perfect Power product below (SMT6 or SMT7) to find the associated wiring diagrams.
Step2: Select from a list of vehicle manufacturers that we have created wiring diagrams for.
