Hi , please help. I am a newby to both forums and Canbus wiring. Bought a butchered Mazda RX8. Got everything working except speedo and tacho. Need wiring diagram urgently.

Here are the pages for the whole instrument cluster.
136901 136902 136903 136904

Hope this helps.

Thanks, for the quick reply. Much appreciated

Had to fit third party injection system, original got stolen. Fitted f3ds motor on the original 6 speed box. Central locking and fuel gauge is working, had to put in RX& hydraulic power steering. Any chance of actual wire color coding to get gauges working?

do any of the stock gauges work or are you only using the Tach and speedo from stock? the stock gauges are controlled by a microcomputer within the stock cluster. I might be able to get the specs on the signals the microcomputer is looking for.

personally in your situation i'd go aftermarket anyway. There are some nice speed/tach combos out there.

The speedo and tach won't work without the stock ECU and the trigger wheel from the RX-8 engine
As well..if the ECU and the Dash unit don't "match" the CAN Bus won't let them talk to each other

What EMS are you using..might just want to use an aftermarket dash unit

I am using a locally based ECU called Gotech (www.gotech.co.za) which I think is basicaly the same as Halltech system. I am driving the engine off a 60 minus 2 crank trigger, with wasted spark.
The system has its own outputs for most gauges except odometer.
Would it be possible to use to drive original revcounter and heatgauge?
I would like to use al the original gauges, but being "old school" these new systems seems rather daunting.
