VE series 2 cluster wiring help

[lukevassallo7]

Hi all, im just putting in an aftermarket tacho/rpm meter in and wondering what wire I take from the dash for the gauge. There's 13 wires that come into the dash cluster. TIA
VE SERIES 2 2012 SV6 UTE.
Couldn't find a diagram online

Don't have a diagram in front of me right now, but I'm 99% sure there will not be any wires you can connect to for either of those functions.

It is all communicated digitally over the CAN-Bus between modules.
