Wires uncovered, again from a 08 Alpha. If you have to snip one of the wires, I would do it in this fashion (giving yourself about 6-8 inches to safely reconnect the wire). Don’t test the white wire as shown here (I was testing something else); look for the yellow and purple wires from the middle connector on pins 17/18 instead.

PCM; taken from a 2008 H3 so may look slightly different than your 2007, but this is the best I could do while being out of the country. :D

I’m almost positive the crankshaft sensors meet in the middle connector, but don’t quote me.

Schematic; look where the Crankshaft sensor meets the PCM, via a purple and yellow wire.
