Ages ago i did the manual conversion on my R34 using R33 parts.

The speedo sensor plug was different, i purchased a R34 Speedo Sensor recently to replace this but it appears the plugs been damaged so i dont know which way it goes, if i put the two wires the wrong way around is the signal going to damage anything?

Goes in for a tune soon and needs the speed signal, if i cant get it working prior i'll just get the workshop to do it, but would rather do it myself instead of paying them.

Cheer's!

No the signal will not damage anything. Both wires should output a pulse from the sender but one goes to ground on the loom end.

I'm fairly sure you can put the wires either way around and it will work but if you put a deutch plug there you can just swap them if it doesn't.

Thread bump.

Where is the speedo sender on a S2 R33 GTS-t?

I am having issues with an intermittent speedo that wasn't fixed with a cluster change so I am guessing there might be an issue with the sender or plug.

Drivers side of the gearbox right near the crossmember

Has anyone had a faulty sender causing intermittent speedo issues?

I cleaned the plug with contact cleaner and had a quick look and couldn't see anything obvious. I don't think it is likely that both speedos are faulty so it seems the issue is between the sender and the dash or the sender itself.

The sender produces its own signal so you can test it at every point in the loom. We usually trace it back to the section of the harness just beneath the fuse box and break it open there. Splice in with our scope and test the signal. If the signal is good, the dash is going to be the problem or the wire under the dash behind the cluster.

9/10 times it's the cluster though. The heat f**ks them up. Borrow a mates, swap it out and see if it fixes your problem

I bought another cluster from another SAU member and the speedo has the same issue.

The advice from Andy at ASR is that he has only ever seen cluster issues, never a sender. When the car gets run for >30 mins usually it comes good so it is temperature dependent.

I guess I will have to get someone to trace the wiring to where the fault is.

      And by the way, I've also checked the ECU diagnostic numerous times and got a bad O2 sensor code and initially an Ignition Primary code, which is why I replaced the O2 sensor and all the ignition components (coil packa, plug and loom). No codes have been coming up lately despite the ongoing issue.

      Hey pber13, unfortunately still no luck. At this point the following has been done with little or no success: - Spark plugs replaced, gapped to 0.8mm - Splitfire coilpacks installed to replace originals - Replaced Ignition Coil/Coilpack harness with a new genuine nissan one - New fuel filter - Replaced AFM/MAF sensor - Injectors have been thoroughly cleaned with an online flush (without removing) - Upper engine and inlet decarbed - blew tons of black smoke out, cleared the carbon deposits from the top of the engine and exhaust.  - IACV removed and thoroughly cleaned with carburettor cleaner - O2 sensor replaced with new and genuine one -  Smoke test revealed no vacuum leaks - Healthy compression test of 160psi across all 6 cylinders Overall the car does run a lot smoother now, no backfires between gear shifts like it did originally... but the rough idle when warmed up is still there. It may not even be a misfire but simply a rough idle. Seems crazy to me that so many people have had this issue and seemingly no one has gotten to the bottom of it, or at least never bothered to post if they did! Hope you have more luck than I did pber13, I'm at a point now where I'm just going to try to ignore it unless it gets worse. Would love to fix it but I've genuinely run out of ideas of what it could be.

      I got the full frenchys kit too. Really awesome kit. Easy to install my only complaint was the hardlines I think could be routed differently (I modified mine) but I realise the kit needs to suit multiple applications. This was the hard lines before I modified them. They were touching the wastegate pipe. I ended up reducing the distance between firewall and first bend. The made it so they tucked along the frame rail.

      Deeve, I don't suppose that you've made any progress on this? My Stagea has the exact same problem, and just like you, I've read through as much as I can online, with no real progress. My car isn't throwing any codes at all, which is a little frustrating. I've changed plugs, checked the wiring and harness. A new MAF gets here next week, but I'm not hopeful it will solve the issue.

      I installed it all myself,  It was really easy to install.  I got a professional to do the degas/gas.
