Need to know where the clutch safety switch gets its power from? Is there a direct fuse it draws from?

Long story short, clutch position sensor has been acting up. Went to the tuner and we bypassed it with a direct wire connection. Went to lunch and it fell out, now the car wont turn over. We direct wired a line from the battery POS terminal to the switch and it fired right up.

Problem is I looked at all IGN/STRT fuses and none are blown. But the switch still does not have power. I cant trace where the break in the line is. Does anyone know where the switch draws its 12v from? Or which fuse it connects to? Better yet where the wire directly goes to in the harness? I trace it behind the steering column but then I lose it.

Need help, tired of this car sitting because of electrical gremlins.

It sounds like you're confusing the neutral switch with the clutch switch. On a manual transmission car the neutral switch should not affect starting; only the clutch switch does. The neutral switch will affect cruise control operation.

Which ever is the switch for clutch in, closest to the firewall. Everyone I’ve talked to shops included have all referred to it as the neutral safety :shrug:

But its the green wire that doesn’t have power. I’m trying to find where it broke connection.

You can get a copy of the Service Manual at https://nicoclub.com/archives/nissan-350z-factory-service-manuals.html.

Look in the sc.pdf section for the diagrams you want.

Found that this morning. Thanks for posting it anyways.

Well after getting a hold of that NICO wiring diagram and saving ALL the PDF's and looking through them this morning.

Coming across the SC and PG diagrams and ended up taking the steering column apart, tracing the wires. Couldn't for the life of me find a burn wire or blown fuse to the IGN system.

I finally came across the IDPM in the PG section, showing its connection to the 43 terminal. After tearing apart the engine bay I found the IDPM (3rd Fuse Box) behind the battery and 2 plastic covers.

Found 4 blown 10 amp fuses. After replacing the first 3... To no luck on the start. I found the 4th one all the way at the bottom. Replaced it and start up!

So hopefully this will help someone in the future with the same issue if their Clutch Pos Sensor shorts out. It should be the (89) fuse slot in your IDPM module box. Which connects to the (43) wire terminal figure shown in the Page 22 of the PG PDF of the wire diagram

Now i gatta figure out what the other blown 3 fuses go to. Since I havent noticed that im missing anything else.
