Just so I get this straight, there's already a cable in the pin 32 slot, you removed the pin from the BCM connector and used a repair wire to connect to the BCM slot 32. Those cables plus the one to the switch are fed into this connector.
In essence, the connector above is basically splicing into the cable on pin 32 and carrying a cable out to the momentary switch which when pressed crosses that cable with ground completing the circuit, but doing it this way you don't have to cut the wiring harness and you could revert back to stock easily if you want to. Correct?
Thanks in advance.
