Hi guys recently bought a volvo 340 and im after fitting an aftermarket rev counter to it.

Does anybody have any good advice for me to fit it.

I know red goes to +..
Black goes to -

Where do the green and yellow wires go?

Any help would be great thank you

Any reason for fitting an after market one instead of an OEM one, which would probably be a bit easier? Or do you already have one and you just want one of those big white ones for the looks

Maybe this post can help

Dependant on which way round red and yellow are it will probably be as follows, black - earth, yellow - constant +12v, red - +12v when ignition is on, and green should be scotch locked (or properly joined) to the coil negative signal. On a renix ignition which you probably have, this will be a grey wire coming out of the renix ignition box (located on the passenger side of engine bay for a rhd car) or if you have a oem rev counter already there should be a wire for this already inside the dash.

Hope this helps
