About wiring tachograph in M818

[MidnightDuramax]

I have a tachograph in my M818 and none of the wiring is hooked up on it. I was wondering if andyone could tell me what pins on the back do what? It would be really nice to see it at night.

Thanx

Old thread bit same question. Found this using the search and tm9-2320-260-20 doesnt even mention it.

i wish my tachograph would work right. they are expensive and very delicate. i might go back to the normal style tach/ speedo

a multimeter and some poking around should tell you what the lights run off, as long as the wires are getting power from the switch.

40A-lights
27- ign hot

I havent fooled with the 3rd one. I figure its the constant hot for the clock.
