912E:
If you have a little time & feel like crawling around try this, but be absolutely sure to disconnect your battery first - as you know, the 912E has some pretty sensitive electronics controlling the FI.

1. Open up the rear fuse/relay cover on the driver's side, engine compartment. You're looking for the so-called "double relay" which basically tells most of the engine electronics that the engine is cranking. This relay is rectangular and sits horizontally against the fender wall between the voltage stabilizer and the FI resistance box. It has two, separate multi-wire connectors plugging into it from the bottom. On these connectors, you're looking for a solid yellow wire. If you find it, first mark the connector's orientation and remove it from the relay. With battery disconnected, run a continuity test from this yellow wire to the wire on the solenoid. If it is, infact the wire you're looking for, this is the wire that goes back to the ignition switch and operates the starter on momentary contact (cranking.) Touching this wire to power should crank the motor. If everything is good to this point, I'd suggest a simple remote switch which connects to the removed connector's yellow wire and a 12v source (I'm going from memory, but one of the rear fuses might be always hot.)
Good luck & remeber to disconnect the battery while you're testing.
