Started the manual swap this morning, I’ve noticed every forum and video the trans loom has 4 plugs under the battery as in the picture shown

I got into mine and it seems to only have 2 plugs.

I think s1 autos might have 4 and s2 have 2. Any info on what needs to be cut or looped for the reverse lights, neutral and inhibitor switch etc would be appreciated or if anyone that’s done the swap knows.
Also just wanted to know if I’m supposed to have a manual loom or starter loom or something? I’ve seen it mentioned a few times but not sure if it’s needed as my trans didn’t come with a loom. TIA

Sorry I'm not sure, but to work it out turn on Ignition, unplug all and check which pin on the car side has 12v (which goes out with IGN).

Then on the gearbox loom side check for continuity between that pin and any other when the auto is in Neutral, that is your neutral switch wiring. Same for Reverse. Probably the same for Park/inhibitor although I guess you will just loop that one. 

I'm not sure about C34 but in R32 the engine sub loom loom has reverse switch, neutral switch, oil pressure switch/warning light, power steering idle up switch, oil temp sender for gauge, alternator wiring and starter motor power and solenoid.

    • yeah first and reverse is where you will find clutch release issues (whether hydraulic or mechanical) because the difference in revs required is the highest there; particularly changing down from 2nd to 1st when still moving. To be clearer though, it is possible that the clutch release bearing is the wrong height. This is less likely than a hydraulic issue but it is not unheard of when you are mixing and matching
    • Quite right, if you make it to that pension you deserve every cent
    • Hi all, Restoring r33 series 1 rb25det. All the heater hoses were on their way out, have replaced them and put it all back together. After testing I noticed a small leak from behind the head on the actual metal water line to the turbo when cars warm. I tried running a longer hose over it but it kept leaking...   I am about to take the (stock) manifold off again😔 to change the water line does any one have any lines they recommend? I was looking at Aeroflow Turbo Oil & Water Line Set but not sure what everyone else recommends. Car is completely stock but want to upgrade turbo eventually. it looks like ill have to disconnect a lot just to replace these lines so if there's anything else recommended to do please let me know. Thank you in advance!
    • From memory, on the R33 GTSt at least, while everyone says "It's not adjustable", I found when I changed clutches in mine, it just needed a small adjustment on the rod length. But be very wary here, as you could end up trying to push the pushrod in the master too far, or blowing out the slave.   Most likely though, if the master/slave isn't bypassing internally or leaking out, then the throw out is the wrong height compared to the fingers on the clutch, so when it moves to disengage the clutch, it isn't 100% disengaged. You can check part of this out too by jacking the car up, having the engine running, put your foot on the clutch and try to engage 1st gear. If it goes in pretty easy (Compared to the ground) and/or the wheels start turning a fair bit and it takes a bit too much brake pedal to bring them back to a stop, this is likely the issue.  I'm not sure if you can adjust the height of the forks etc in these though, it's been that long since I've touched any RB gearbox.
    • That's all good, I thought I was missing some interesting feature! Maybe @PranK can double check if that is something that is meant to be operating or not.
