-5dc Questions

[battletoads]

1)  Ok, the cabinet that I recently bought has a 'Battletoads' PCB in it. 

The pinout for battletoads is here:

I just bought the pcb of 'X-men', whose pinout is here:
http://coinop.org/kb_dl.aspx/KB/Pinouts/X-Men.txt

When I compare the two, I can see that in the "E"slot the X-men game has a -5dc wire, but battletoads doesn't.  What problems will arise when I stick the X-men pcb in when it arrives in the mail?

2)  Also, the cabient was originally a 'Gauntlet 2' cabinet and although 'Battletoads' is a 3P game, all 4 coin slots are somehow rigged to the Jamma cable.  Now I bought Konami Jamma+ cables and Ive got them ready to go, but I can see that they have a coin slot wire in them.  Do PCBs like 'X-men' REQUIRE the coin slot to be hooked up to the wire in the Jamma+ harness or will I be ok with the current wires that go from the coin doors to the main Jamma harness?

Thanks!
