Help installing SIP digital speedo

hi all,

i just bought the digital SIP speedo for my PX200 disc with battery , year 2006. I tried installing it following the manual, but i have a problem with the power cable. I installed it on the light power supply but that only gives power when motor is running. I want to see the speedo working with ignition ON. Then i tried the red power cable from the ignition switch behind the nose, but that gave me a working speedo all the time , even with the ignition OFF. Does anyone knows which colour/cable i could use inside steeringhouse or under nose suitable for power supply with ignition ON and no power when ignition OFF ?

cheers !

I've watched it several times  :) it's the power cable I'm looking for...
