this is for a 92 Mazda B2200,

I need a tach signal converted to 12V constant, non pulsed - is there a converter or does anyone know of a diagram to make one?

Peace!

if you only want voltage when the engine is running why not just use the oil pressure switch to trigger a relay? if your truck uses a sender and not switch, you can get a N/O oil pressure switch with what ever size pipe thread you want at any parts store along with any fittings to plumb it in.

I was thinking of that,

it might be easier if I went that direction.

Thanks

To convert a tach signal to a digital signal you just need a frequency switch - do a Google search they are pretty cheap and easy to come by.
