which wire to upgrade solenoid spade

[SemperVee]

 My wiring colors do not match from what little I understand on the wire schematic for the 07 Norge.  My starter relay has Yellow, Orange/yellow grey/red and Red.  which one did you tap into to upgrade solenoid spade?  My Yellow is upgraded and fused to battery already with 20amp fuse. So I think I figured out the orange striped one is the solenoid one to tap into and replace the skinny OEM one.

I sent you a PM this morning.
The wiring all the way from the battery through the relay contact and to the starter solenoid needs to be capable of passing 50+ Amps for a split second.
I'm not that surprised the colours don't match the guzzi factory haven't shown much discipline
Looking back at drawings I can see they have been making lots of changes over the years to solve the failure to crank issue.
Can we even find a drawing of the starter solenoid showing two coils all the Guzzis I have seen have 2
