Clutch Switch In R33 Gts-t

[aaron_25t]

I was going to wire a clutch switch to my ECU for launch control/flat shift.

Found there was already one there in the clutch bracket.

Any one know what this is used for?

I could put another switch there but that would involve making up some brackets etc. If I can use this existing one I'd be stoked.

If it's not used for anything I could wire straight off it, or if it is used - I could wire up a relay to repeat the status of the clutch to the two circuits.

If anyone has a circuit diagram that would even be better.

Thanks,

Aaron.

OK got a bit more information:

The clutch switch has its own error code in the HICAS diagnostics. Is it just used for HICAS?

I have a HICAS lock bar on the car so might not need this and can rewire?

Anyone?

I've managed to get a copy of the engine chapter of the workshop manual - doubt it's gonna be in there but will have a look tonight.

Otherwise I'll have to trace the circuit back...

i have had my clutch switch hooked up to launch controll (gizmo launch interface) in my r33 gtst and had no issues with Hicas.

So i dont see how you will have any issues if i did not

Excellent, just what I wanted to hear - thanks for that.

Did you cut the existing wires off and rewire?

How's the Gizzmo? Find it useful? Is the flat shift more a lil more beneficial than the launch control in a RWD?

I never actually set it up properly yet.. lol... I kept showing off pop pop bang bang and it cost me a gt35r so I leave it turned off now

Ouch...how long did you have it before it went? Maybe not such a good idea then...

Did a search and some guy had one for sale a while back and wired it like this, looks like you got this one Hope you don't mind me pulling this pic up:

Thought i had this sussed but what is that rectangular object all taped up in the pic with the terminals coming out?

hahahaa thats in my car atm

It was in there for about 2 months.. i gave it a little workout but not as much to wreck a perfectly good turbo, my turbo was flogged for years before this unit came along.. it just speed up the process.

Its a relay, the mafia hooked it up because the switch is the reverse of what is needed he made the relay setup for it which worked well

[aaron_25t]

Ahh thought so - all sorted now.

That makes sense now, I need a normally closed contact, I'll test the switch tonight to see which it is and whether I need the relay.

Thanks for the help
