Rev counter wiring - injection / carbs issues

[teej]

I'm curious as to how I can get a working rev counter in my car.

It's a GTE, but at some point has been converted to carbs, and although (some of) the other dials work e.g. speedometer, the rev counter doesn't. Would I be right in guessing that the rev counter relied on some part of the electrics that got junked with the carb conversion?

Is there a way to get a rev counter up and running? Do i need something aftermarket especially for carbs - this might be best solution as I'm not an electrical wizard.

Cheers!

I'd guess the GTE dials would run a wire from the ECU for rev counter signal, assuming this has all been ditched for the carb setup. A cable from the coil negative terminal should work though

Thanks.

As Razorjack says, a wire from negative terminal on the coil on my 1.2 carb runs to back of rev counter on GTE dials. works fine.
