I have a Defender 110 300TDI with a Puma dash conversion. I need to get the rev-counter, temperature gauge and fuel gauge to work. The speedometer works btw.
I understand that the rev counter can be made to work by getting a signal from the W terminal in the alternator, but I am unsure if that will work with a Puma gauge cluster, I don't wanna risk ruining the gauges.
So how can I get these gauges to work?
