FUSE it and consider using a relay. In fact consider using a relay to feed the choke, the VR, and the ignition power
Electrically speaking, you cut the blue "ignition run" wire coming out of the bulkhead connector, trigger a relay with the bulkhead end, hook the engine bay end to the output (contacts) of the relay, and run power to the relay through a fuse/ breaker off the starter relay "big stud." That leaves the relay ground. You could run that wire (if you want) to an "less - than - obvious" switch for a small measure of anti theft
