2. Vehicle Harness Connection (36-pin): If your car uses a 36-pin socket, locate the corresponding 2-pin CAN plug and socket on the wiring harness and connect them to the car's cable harness.
3. Vehicle Harness Connection (40-pin): If your car uses a 40-pin socket, locate the corresponding 2-pin CAN plug and socket on the wiring harness and connect them to the car's cable harness.
4. Direct Gateway Connection (if no CAN-Bus in 36/40-pin): If neither the 36-pin nor 40-pin socket of your car's cable harness contains a CAN-Bus connection, use the provided 2-pin CAN-Bus cable to connect directly to your car's gateway. Refer to the wiring diagram for specific CAN-H and CAN-L connections.
