    Default DSP2 switch not working

    i was wondering can u ground the switch to any metal on the truck or does it have to go to pin 37 as the ground. reason i ask is the guy that gave me the pin only gave me one and then said to just ground the other wire.

    You can strip the tip of the wire (1/32") and push it into the PCM slot.
    I did this with my fuel pressure sensor wire until I bought the pin, it worked fine.

    Any ground seems to work ok. But technically the ECM's ground is ideal.
    I no longer monitor the forum, please either post your question or create a support ticket.
