Wiring up a motometer tacho?

Managed to bag a super rare motometer tacho for my 58 ragtop resto. Very Happy

However, being a 30-40 year old gauge not suprisingly it came with no instructions! I dont wanna wire this wrong as I'm NOT gonna find another one, thus I was wondering if anybody know how to wire this in to the car? Confused

The car its going in is a 58 bug, but running 12 volts electric with a full MSD iginition system (It can be tested in a standard t25 bus or 6v beetle though). Pictures below shows the gauge, and connections.

At a guess I'd think the switched live goes to terminal '12', it needs to be earthed to the '-' treminal, and the tach output wire needs connecting to the 'z' terminal. However, as its a older gauge do I need a MSD tach adaptor?

Cheers in advance for any advice. Smile

I don't know on this one but on all the other vintage tachs I have used, the coil connection goes to "1". I assume that is "Z" on this gauge.

The rest is as he said.

Anyone in the whole world have any info at all? Confused

Answer:

Z - green wire to the coil (neg)
12 - red wire to the ignition (fused) if 12v
6 - same if 6v
'-' - black wire earth to your chassis
light - white wire to your light switch

Cheers Very Happy
