Y'know, Sometimes the simple things escape me.  ::)

I'll have to check to make sure it cuts the ground however. If it doesnt, could i damage something?

jimkirk:

What I did on my switcher is installed relays to cut power to the slots when not in use. Here is what I did

1. Run a wire from 12v pin on desired slot to 1 coil pin on relay.

2. Run a wire from edge connector ground pin A,B1,2,e,f,27 or 28 to the other coil pin on relay. ( changed this part,forgot coil pin)
    Now the relay is energized when the slot is powered.

3. Run a wire from the edge connector -5v pin to com pin on relay.

4. Run a wire from N/O pin on relay to -5v pin on the slot.

Repeat for each slot that needs -5v.

Here is the relays I used.  http://www.radioshack.com/product/index.jsp?productId=2062483&cp=&sr=1&kw=relay&origkw=relay&parentPage=search
If you do it this way those slots with the relays will only get -5v when it is in use.
Any questions feel free to pm me. It isn't hard to do,it was my first time using relays and had no problems. One more thing you might want to mount the relays on a bread board then mount on cab.

So I guess that means that the switch doesn't cut the ground ...

Um...pictures please?  I think I follow what you're saying - but I haven't ordered this just yet, and a visual would be *very* helpful.

I can't take pictures of the switcher,it is too much work to remove from cab.
It is buried behind pcb's and under a shelf. I used extension harnesses to the pcb's.
I will try and make a drawing showing what I did and post it tomorrow.
That should clear things up for you.
It is not very hard to do,if I could do it anyone can.
All connections were on the switcher except the ones on the relays.
