95 Sentra Starting issues

Hi folks,
1995 Nissan Sentra 106,xxx miles. 5 Speed manualw/1.6L

The starter does not engage at all, and I hear no solenoid click. Battery is verfied good-Everything else has power.

I played with the clutch interlock switch by jigging the wires and depressing the little button while trying to start, and no go there. I hear relays clicking when I turn it from Run to start, so I assume the ignition switch is okay.

I also tried hammering on the starter/solenoid while ignition was in start position, with clutch depressed, and nadda.

Can you guys give me specifics on where to start? I have a wiring diagram, but it doesn't tell me exactly where the clutch interlock is located. It actually calls it a module...

Thanks in advance!
