I've added SS gauges and dash harnessalong to my car. I've looked at the assembly manual to try and figure out the location of the hole in the firewall to pass the brown tachometer wire through. I know that I need to drill the hole however it's difficult to decypher the location using the schematic in the A10 section.
Does anyone have a good picture of their firewall where the tachometer wire comes through so I can drill in the right location? Added bonus question.. is it suppose to be a 3/4 in. hole?

Thx in advance - Tim
