copied from BarbyCar in the LED gauge cluster thread....
Here is the pinout for the 2000 if that helps.

They are in the wiring diagram section C-a and C-b but for those without diagrams, here they are:
There are three connectors 1, 2 and 3. From the driver's seat 1 is on the left, 3 in the middle and 2 on the right. Each connector pinout starts at "a" and the blue circuit is labelled with an appropriately placed "a".

1a= BR/B - Fuel System (ECU and fuel gauge sender)
1b= BR/Y - Cruise Light (from cruise module)
1c= B/Y +12v Switched (from meter fuse)
1d= No wire or P/B - If applicable, ABS light (from ABS module)
1e= No wire or R/W - If applicable, Automatic O/D light (from transmission control module)
1f= L/R +12v Unswitched from Room fuse
1g= Not used
1h= W - DRL module (high beam light) - No wire if no DRL
1i= R/Y - Headlight relay (via LH headlight fuse) - note R if no DRL
1j= not used
1k= not used
1L= W/R - Door switch (interior lights)
1m= Y - Speed sensor for manual. No wire for automatic
1n= B/L - Ground
1o= not used
1p= V - Start signal - from ign switch on manual. B/R from transmission control module if auto

2a= V/W - Water temp (from temp sensor)
2b= L/W Seat belt (seat belt switch - driver's side reel)
2c thru 2j not used
2k= G/O - ECU (and data link connector - also transmission control module if auto)
2L= W/B - ECU and cruise control module
2m= O - Speed sensor for manual. B/W from transmission control module for auto
2n= not used - goes to empty lamp socket
2o= W/L - ECU - controls CEL
2p= not used

3a= G/B - Left turn signal
3b= BR/R - ECU
3c= L/Y - Brake fluid light (and DRL control module. If no DRL then also to parking brake switch)
3d= BR - Air Bag module (and data link connector)
3e= Y/R - Oil Pressure "gauge" switch
3f= L/O - Key reminder switch
3g= R/B - Instrument lights +12v from TNS relay
3h= GY/R - Instrument lights dimmer control to ground
3i= G/W - Right turn signal
3j= B - Ground (connects internally in cluster to high beam light if no DRL)


L=Blue, B=Black, BR=Brown, G=Green, GY=Grey, O=Orange, R=Red, W=White, Y=Yellow & V=Violet

I've got one of these at the house. They are a good investment as a Miata owner.

I would scan the info but I'm not where it is.
