Tachometer Signal

Gents,

Where is the best place to connect to the tachometer signal. I ask as I a have the cluster apart and have access to the plugs at the back.

From the wiring diagrams (1998) I have and posts it appear that it is plug II (white), gr/vi (I think this is green/violet; I hope I can actually discern the colours). I could solder a pin and insert into to the connector. This will be a bit messy.

Which OBDII wire is the tachometer signal? Would it be better wiring practice to use a wire tap (if so which type) and just grab switched 12v there as well? The wires I am trying to connect up are a very fine gauge.

A present it would be easier to order wire taps online rather that grabbing soldering equipment.
