Trans Brake Switch and Creep to A13 - But already used?

[Justa6MB]

I've been doing some reading on the subject over on CPGN. My creep isn't working right yet and have read that using A13 as a ground source for the switches has helped fix some issues. However it appears A13 is being used, or at least there's a wire leading to the kick panel in my GN. I doubt I want to just tap into that wire. So can I use A12 as a ground source instead? A13 shows Distributor Ground. A12 is Main Power Return (Ground). And can I feed both the trans brake switch and the creep button off of the same switch - A12? Or should I be using another main power return high current pin ground for the 2nd switch? Also I've got the launch switch T'd into my AMS500 boost controller for ground activation. Is there a better way to do that to ensure no ground bleeding occurs?

Don't use A13 that's the return for the CCCI. I have had good luck just using a good chassis ground
