  • P1900 Grounding

    I am wiring up a P1900 to my Dell Inspiron 8600. I know that I obviously need to ground the input connector to the car. My question relates to the output ground wires.

    Is there any difference between the ground wires on the output connector of the P1900 and my ground point on the vehicle chassis? Also, I have the Carnetix 5v adapter installed. For my 5v devices, do I have to use the ground wire coming out of the 5v regulator, or can I use any ground wire I want?

    I'm thinking that these things should all be ground, so it really shouldn't matter...but I wanted to make sure that there wasn't some kind of difference between the output ground wires and my ground distribution block.

    Thanks in advance!
