Great diagram Charles, but on my 2012 its a bit random. I would however love to get my hands on a true (readable) wiring diagram?
I doubt there is a single wiring diagram in the public domain.
My understanding is that there are broadly three electrical systems.
1)The s&s VFI wiring harness which is in the x wedge manuals. This concerns engine management including emissions.
2) the morgan system for the instrument binnacle, fuel pump etc.
3) the cycle electric alternator and rectifier for charging the battery.
I dont know if the speedo, indicator and urban coolong kit are run from an ecu in the instrument binnacle or are part of the s&s vfi ecu
