Fitting an aftermarket rev counter

[Fin]

Thought I'd get one,
Where the bloody hell does the wiring hook up? ie: what wires do I need to attach to where?
What's the rev range of a 1.9 WBX and of a turbo'd wrx scooby
i have the first fitted and the latter is waiting in the shed

got quite a nice rev counter out of an old tractor with a 10 in dial, was gonna run up a swanky pod for it on the lathe

there's a write up in the wiki for fitting one.
But basically you need to run a wire from the coil
an earth and a power wire for the illumination



you can get gauges fro Demon tweeks.. http://www.demon-tweeks.co.uk/Performan ... l_Kits/792
I would recommend the TIM gauge (pictured here)

You can run a new wire from the coil but you don't need to. A lead from the coil is already at the dashboard (along with all the others you need!) on a van that has a buzzer of doom (and yours being an '89' model will have a BOD). I posted the circuit details in the thread below (click on the diagram to enlarge) with the pin numbers on the edge connector that feeds all your instrumentation. You can tap into these wires at the edge connector for your new tacho - Tacho pulse (9), Illumination (1), Earth (3) and 12V (8) ......if you need the colour codes then let me know! Wether you tap into all of them or just the tacho pulse wire is up to you (and wether you have an aversion to using those compression fittings that some people hate - used appropriately I find them useful)...............

Nice one Angelo.. I guess my post was basic, the BOD is more refined

If it came out of a tractor then I would assume it was a diesel engine and will be worked by a phase signal from the alternator not an ignition signal. You might need a frequency pulse converter otherwise it will doing 4000 rpm at idle

Cool - Thanks for the info guys, I'll dig about under the dash
And maybe buy a new rev counter
