Ok after trying to find the shudder that occurs some times when putting IN the clutch, ie checking rear gear box mount...(note I am yet to find the problem)

I noticed TWO plugs on the drivers side of the gearbox casing. One had a balck cover the other blue, both with two wires.

Now the problem is the black one is connected the blue covered on is not.

Can anyone tell me what these are for??

Why is the blue one not connected???

Should it be connected, considering I cannot find the female side to connect it??

Dammit I need one of those workshop manuals :flamed:

Hmm, that's strange. It could be a series 2 thing, but I dought it.

I've seen these two plugs on 2 x R33 GTS-t's, 1 x R32 GTR, and 1 x R32 GTS4. So my guess is that it's right accross the board of R32 and R33 manuals.

One plug would be for the reverse lights, and the other may be a speed sensor ?? I know that the speedo cable is plugged into the rear of the box, so I'm not sure why it would need 2 speed sensors... :)

Maybe an overdrive (5th gear) sensor?

Do your reverse lights work??

Yeah reverse lights work, just cannot locate anything that may in fact plug into it...

And I am sure that the speed sensor/limiter is working if you get my drift...

I have had a look at a series 1 and it had the same plugs, but the gearbox had been replaced with an unpsecified year second hand box...

One plug is the reverse switch (closest to the front of the gearbox). The other is a switch to tell ECU when the gearbox is in neutral or 5th gear (I can't remember which off hand). Shouldn't affect anything greatly if its disconnected and won't be the source of the shudder, which sounds like it's related to the clutch itself.

Thanks Steve, I thought that may be the case, its coming out of the box, an auto box would be completely different...

As for the shudder I am thinking of taking the box out as the throw out bearing is making some noises...maybe the alignment of the pressure plate is cactus.

I think the black one (closest to front of car) is the reverse one definitely cause the reverse lights still work...just weird that the other one has no friend...

Thanks

    • It is a kunfine Android screen . Does anyone know the wirering diagram of the fuga ??
    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
