I am ready to wire in the MS and the GM DIS and I need a power source for a relay that gets power when the bike is on run, but NOT start (ie not when cranking). thanXS

Hmmmm
Does it need power prior to hitting the starter? if not, then perhaps off the headlight power?Life is what happens while your planning everything else!
When your work speaks for itself, don't interrupt.

Looking at the wiring diagram, you'll find power on 3 main wires
the red wire from the igintion (key) switch, for that matter you could probly
use the red wire from anywhere, but it looks like that carries power at all times when the key is on,
the r/y (red/yellow), also from key switch, cant remember if it carries voltage when cranking or not
the brown and the blue also carry power, but for lights
you'll also find power on R/W1980 XS11 Special aka The Monster

81XS;
What I think you wrote was that you want a power source that will be live with key in ON pos, then will drop out when you hit the starter button?? Then come back live when you release the starter button??
If so, use a SPDT relay, wire it's coil in parallel with the starter solenoid and use the COMMON & NC contacts on the relay to switch your source. When you hit the starter, the relay will pull in and disconnect. Source your power from any brown circuit. Watch your amps draw, you may need to up the rating on the fuse in whatever circuit you use.

What about using one of the relays that has the 87a output? I could set it up so that the 'run' power came from the 87a pin and the relay was triggered off of the starter power. That way when the starter received power and the bike was cranking, the relay would disconnect the power from 87a and put it to 87 (which wouldn't need to go anywhere).'81 XS1100 SH
