Help drilling hole through firewall??

[slappedvr]

hey guys
im attempting to fit a water temp gauge into my vr.
i cant find a spot to drill through the firewall for the sensor/sensor line.
anybody know where i can drill through?
cheers

are you installing an electric temp gauge
if so you only need to run 1 wire through the firewall for the temp sender
can you poke a wire through one of the rubber boots in the firewall that already has wires going through it
if you do just dont force it through with something sharp

nah its mechanical.
all good i found a hole under the glovebox.
also mate you wouldnt know how to wire up the light of the gauge would you?
cheers

so turns out the sensor line wasnt long enough.
is there any places under the steering wheel where i can go through. because its tight as **** under there and i cant see any openings?

Go though were the heater pipes go though the fire wall - and use a little CRC to lube the hole .

The brown white wire supplies power to the globes in the cluster and dash switches. Hook into that and the earth to a black wire.

Yes there are a few brown white wires running in the VR dash loom. Pick the one right next to the purple white wire at the main dash plug connector by the drives air vent. Take a wire off that one and see how you go. You could also come through next to the main loom entry point. Take the window washer bottle out and you should have enough room. From memory there is nothing next to the main loom entry point.
