This was covered in this thread, and in some others:
http://www.valkyrieforum.com/bbs/index.php/topic,63609.msg618798.html#msg618798I wrote it up on my tech tips page:
http://www.horseapple.com/Valkyrie/Tech_Tips/Fuel_Shutoff/fuel_shutoff.htmlIn a nutshell, this design includes an LED to indicate when the solenoid is powered. Also the default is, the solenoid is off until you hit a hidden pushbutton which activates a relay wired as a "latch" - that is, when activated, it holds it's "on" status until power is cut by the ignition, kill sw, or tipover function. So it's anti-theft and anti-hijack. Someone steals your bike by hijack, hit the kill sw and hand it to him. Or if he gets your keys and rides it away. Either way, in a mile he's outta gas. Call 911 on your phone and tell the cops where they will find the thief on the side of the road. Doesn't take you long to automatically hit the pushbutton after starting it.
Get the 12v aux power from the black/white wire at the kill button output, or the same color wire at the ECM, or at one of the coils. No, that does not create a problem with ignition - mine has been wired this way for over a year - and same for several other riders. One guy reported a problem but it appears that was caused by another issue.
Here's the schematic again, thx to BonS for diagraming my install, and also for the D1 improvement:
