Hi All, Couldn't find anything on this topic so hoping someone out there can help.

My cluster stopped working so I had to replace it with a stock second hand one. My car has around around 75,000 km and the replacement cluster has 51,000 km on it.

Wanting to know if there is a way to increase the reading so that my odometer stays consistent?

Haha yeah there is that option but I don't have the time.  No service history, so would be good to adjust it somehow.

In NZ the km's get registered on a site called CARJAM so would show up as an inconsistent odometer if I left it how it is now.

And as long as you're open with it and there is some way to note it in CARJAM, there really shouldn't be any problem.

Your physical solution is to go buy a cheap Chinesium cordless drill, connect it to the speedo drive (pulled out of the gearbox) and sit the car in the garage with the trigger cable tied until it has done 24000km. That would suck, but it would work.

Your electronic solution is to make an Arduino to output a sine/triangle wave of about +/-1V and pulse it at whatever frequency is broadly equivalent to 300 km/h and let it run until the odo winds on 24000km. That's about 80 hours, or a long weekend.

I'd suggest take a photo of the two clusters together. Make sure you're upfront if you ever sell and you might be ok (depends on the buyer then).

Hmm, sounds like there's no easy approach to this. Might just have to document the change and live with the 24,000 km decrease on CARJAM. It doesn't bother me and to be honest I'd live with it if I was going to keep the car forever, but I will eventually be selling it to buy a house in a couple years and worried it might hurt the resale value.

Is what it is, I guess it would be OK if I keep the broken cluster as proof. Would've been nice to keep the records clean though.

Yes, in regards to resale: all you can do is keep the old cluster, any documentation (take photos) and be up front about it.

I looked at a few cars that nismo cluster swaps, it didn't phase me (and shouldn't phase an educated buyer) as long as there's documentation to explain the discrepancy :) (y)

Remove the cluster from the car, remove the odometer from the cluster remove the speedo odometer and you can pretty much use your fingers to move the dials around to get to the position you require

Email LTSA with the previous kms, the new kms, why you swapped it and a receipt for the new cluster.

It'll still show inconsistent speedo on Carjam but will be legal, Auckland Instruments or Robinsons could probably wind it forward otherwise.

      Does anyone know whats happening with harness on drivers door?

      The two diagrams are equivalent. The R32 one is just one sheet out of about 3 showing everything in the whole car all at once. And without knowing the functionality that occurs in the modules, they are both equally opaque.

      Thanks for your reply,  Those blue/green wires running to the actuator aren't attached to anything, so I'm not sure how the central locking is still working. I will have to take a good look tomorrow, I don't have the car with me. After googling it seems like a pretty common aftermarket actuator which even uses the same green/blue wires the immobiliser required. i'll test everything tomorrow and if it's working i'll melt the solder, strip it, resolder and neaten it all up with some heat shrink. I don't have to understand it if it works hahaha I just don't want a fire/ short circuit. That R32 diagram looks more like a continuity chart? Can you make sense of this form the R34 manual? 10V is probably due to very flat battery, i'll recheck as well tomorrow, I did have to jump start it haha. Thanks again!

      So, COM doesn't mean comms. It means common. What common itself means will depend on the type of device. For a two directional actuator (ie, one that can push and pull on the same output rod) then the common will typically just be the earth connection. There will be at least 2 other wires. If you put 12V on one of the other wires, then the actuator will push. On the other 12V wire, it will pull. Can't quite make out what is going on with the wiring of your actuator. It appears to have several wires at the actuator plug, but there only appears to be 2 wires where its loom approaches the door control module, with at least one of the others cut off. I don't know these actuators off by heart. I'd have to look at a wiring diagram for one before knowing what the wires were about, and that's despite me having to replace one in my car not all that long ago. Just not interesting enough to have dedicated memory set aside for trivia like that any more. That actuator is an aftermarket one, not the original one, which probably died and was replaced. That might require some sort of bodge job on wiring to make it work. Although nothing should justify the bodginess of the bodge job done. As to the soldering job on the door module's loom plug. Ahhahhahaha. Yes, very nasty. Again, I cant tell you what any of those wires do. You'd need to study the R34 wiring diagram (if you can find one that shows the door module). I don't think I have any. I'd have to study the R32 diagram to start to understand what mine is doing, and again, even though I've had a problem with mine for the last 25 years (where it locks the passenger door when the driver's window reaches top or bottom of travel) I'm just not interested enough to try to to work it out. So long as it's not burning down, it's fine with me. Here's the R32 GTR diagram, which, confusingly, has rear door lock actuators and window motors on it!! As you can see, unless you understand the functions of the door lock timer and the power window amplifier, you'll never be able to work out how it works just from the diagram. I don't imagine that the R34 one is any better. Hopefully an R34 aware bod can help. FWIW, the two wires that are cut and joined look like they are both power supply - so hopefully it is not fatal to join them. The 10V you measured on the cut off free end of one of them is concerning. You'd expect 12V, and it might be the reason for the bodge job joining them together.
