If you don't get an answer, try putting a length of wire from the starter terminal on the actual starter, the other end get it near the ignition block and with a meter set to ohms, see which you get a full reading from,./ is that clear, or not..??
Should be easy to tell.
One will probably be 12v permanent
One will go 12v when the switch is turned.
The other one will go 12v when you fire the starter. Otherwise known as 'the other one'
Or disconnect the battery and measure the resistances between.
Please let us know how you get on with the keyless start. I've been pondering a PKE system myself.
