Guys,

Here's a what I think is the clutch interlock relay on my 89 240SX.

I'm trying to track down a starting problem. I'm getting juice coming out of the steering column ignition switch. The black/Yellow wire is giving me 12V in the Start/4 position at the steering column.

I'm getting a 12V reading on the plugs to this relay in the photo but no juice at the starter solenoid.

Any body know where the Cluch interlock switch is located?

Check under your dash. The clutch itself has a lilttle rubber stopper that pushes against the clutch interlock switch. It has a habit of falling out. You can try to fix it for cheap, or just leave it out and have yourself a free kill switch.

As far as the technical goes what you have pictured here is the interlock relay The big plug going into it is coming from ignition to starter, the smaller plug is coming from your clutch interlock switch (and ground) going to ignition.



Go back and retighten your batery connections. Check for corrosion.

Hope this helps.

That is the inhibitor switch you need to jumper if you're doing an auto-5spd swap. It's by the passenger side fusebox, mine was tucked up under it. If you want a functional inhibitor switch, you can just run those wires into the dash and hook them up to the switch at the back of your clutch pedal.
