Where exactly is the flywheel sensor in an M103 (91 300SE)? I'm about ready to lift the head with manifolds attached. The flywheel sensor wire is clamped to the manifold in several places. I might as well lift the wire with the assembly. One end is at the ESL box, easy enough to see. Where's the other end?

Thanks,
