where to plug up cam pos sensor?

OK guys I have replaced the heads on my 3400. I am almost done, but cannot find the plug the camshaft position sensor plugs into! Which harness does it come off of? There's one that runs across top to alternator, and out of it comes the injector wires. On the other end are all the ones for the throttle body sensors and such. Nowhere do I see the 3 wire plug for the cam sensor! I must be getting old!

It should be on the crankshaft, under a shield.
Lower pulley, just behind...
