Dakota digital/speedometer wiring help

[jackm]

Hi,

So ive got a dakota digital to go in the car. So far ive got the speedo loom exposed etc and got the ground/power sorted for the dakota digital. Reason for this is 350z gearbox is going in and i will be getting the speed signal from the rear diff sensor. I have an S14 with the crossover s14a loom etc in the car by the way if that helps.

My problem now is what wire provides the signal to the speedo/which one do i need to conect up to get it working.

I have the FSM open and im not confused as the manual seems to be confused as to what wires are in the plug and the location of them.

Here are some pictures:

So this is the plug thats for the Speedo:




I get the colour coding for which one iswhat but i need someone with a bit of a better understanding of the system to identify which one of 28 or 35 i need to conect up to the dakota to feed the speedo and which ABS wire from the sensor do i need to splice into to get a signal.

Ultimately i would get a 'how to' up as a step by step guide as it seems a bit thin on the ground.

Here are some more pics to see if they help:

Hey mate,

Sorry to hijack

Not sure if I have the same question as you, or that you may be able to answer mine.

Which wire is the speed sensor going into the back of the speedo cluster?

I thought it was 22, but I have spliced this and used a speed converter from kbtv and it does not convert from kph to mph (22 is what he identifies in his fitting guide - but he states it is yellow?)

Any ideas?

Cheers
Chris

EDIT:
Not sure what I have even cut, I think hes describing 22?

Hi,

I traced the board on the cluster to find the speedo wires etc then looked at the FSM. if you imagine the plug im holding upside down, then the wires are:

22 by the FSM is a ground (black wire) 21 is ign power (green) and 28/35 are signal wires from the sensor (yellow/green 29 and red/yellow 28).

Was thinking that when i was typing, replace where i say 22 with 29 and it should make sense??

[CEmm]

Sorry what does FSM stand for?

So ive tried 29, ill try 28 to see if that is the speed sensor?

Ill delete these comments in a bit mate to give you your thread back!

Looks right to me, just rotated 180.
You do seem to be missing a wire for pin "27" - you don't show the full page from the manual, I suspect it's for something you don't have like auto "O/D" warning light.

Pin 35 will be on another 10 pin plug (under your big finger?). Plug 1 pins 1-10, plug 2 pins 11 to 20, plug 3 pins 31 to 40 and plug 4 pins 41 to 44.

The speed sensor is a pulse generator that produces 0.5V AC so it shouldn't matter which you connect to.

Have you tried windows start, all programs, accessories, snipping tool?
Or
Acrobat reader, right click on toolbar, edit tools, take snapshot?

I've no idea which connector this is but it's not the one above. Pins 31-40?

If that red wire with a bit of brown tape round it at bottom right is pin 35 then it will do.

No shouldn't be pin 22 at all. That's black and is the earth.

Pin 28, Red wire with Yellow trace.
Pin 35 RED wire.

FSM = Factory Service Manual.

Sorted!!

Red with the yellow worked!!

So the black is earth (22) do you know which is power? So i can run this converter behind the clocks and dont have to run this wire from the fuse box
