Details on what wires go from MSD rpm switch to TACK & Computer

I need details on what wires run from the MSD switch to the TACH and COMPUTER. Does anyone have links or a diagram?

Run the MSD in 4 cyl mode (LS1, right?), which means you cut the little loops.

Ground = Ground
12V+ = Wire to 12V+ when ign is on
RPM Feed = #10 or #12 on the ECU, check ls1.com FAQ
Ground Signal = This is what the Switch sends to turn on the relays to fire the juice.
