anyone got any info on the above

im wanting to fit kph-mph converter, but dont have wiring diagram ???

That could be difficult, because of the differences between convertors etc

BUT:

 

Red - 12v supply from back of clock.

Green - Earth taken from back of clock.

Yellow - speed convertor input from loom (cut wire and connect to loom end)

Blue - speed convertor output (connect to the cut wire going to connector)

Grey/white - don't know, on my example it is taped up.

I believe the wire to cut is yellow with blue stripe, again, it is on my example.

 

I do stress though, that this is how it is on my example, it is not forced to be the same on your car. I have an import auto TT.

yeah mine are the same coloured wires

but i dont know which connectors/wires on back of cluster, to connect to ???

Right, at the back of the speedo there are 3 main connectors, 2 together on the LHS and one on its own on the right.

The connector used on mine is the top LHS connector. On that connector there is a yellow wire with blue stripe. That is the one to cut. Connecting yellow to the loom end and blue to the connector end, effectively putting the convertor in series with this wire.

Again this is how it is on my car, an import TT auto series 2 (1993)

That just leaves the red and green wire to use. On my unit these have lugs crimped on them. The actual speed clock is held in the cluster by 4 screws that also form part of the circuit. The red wire connects to the bottom screw with the lug and the green connects to the right hand screw (the one nearest the center of the cluster if you like).

Feel free to ask any more questions if this doesn't make sense, but I'm assuming that you have the same setup. It MIGHT be different if you have a series 1 or 3/4 car.

Just another mention though, I am fitting UK clocks to my car and doing away with the convertor because powersteering, HICAS and autobox are all speed sensitive. The convertor fools their ECUs into thinking the car is going slower than it is which MIGHT effect the steering (make it lighter), gearchanges on autos and HICAS steering. This is because it is the speedo cluster that provides a speed signal to their control units and the speedo is effectively fooled into reading 1/3rd slower and then you just put a MPH sticker on.

This I add, is just what I think. I have done a lot of searching in this forum and I am not the only one. I have also checked the circuit diagrams relating to the speedo, steering and autobox and they show that speed sensor feeds speedo, speedo then feeds the various ECUs.

My car runs fine with the convertor in, but I find my steering very light, I have never felt my HICAS work and my autobox does make some funny decisions on when to change and I think the convertor is the cause. Like I said, not a problem as such, just not as Nissan intended. Plenty of people though do run with convertors without fault.

Search 'speedo convertor' and 'convertor problems' sift through and make your own mind up.

mines a (91)

so i suppose this is a series 1 ???

will have a look at weekend

thanks for info

cheers

Yes, its a series 1.

Good luck!

might look at the uk clock install, if problems occurr

is it just as straight forward as swap clocks over ??

Yes, if you get a series 1 uk clock set it should be a straight swap. Not sure if a series 2 clock set will fit straight in though, so best try to source one the same age type as your car.

Search in the Trader section on here, look for SWZ parts, there were some uk series 1 clocks for sale just a couple of weeks ago.
