Help with a oil pressure gauge install

Thinking i should invest in oil pressure and temp gauges, i can easily wire the electrics up, but need some help wiring the sensor part up, where do people mount these, i want quick and easy mount not having to install various fittings etc, do people remove bungs from the head or something? best diy solution?

You wouldnt happen to have a link showing an install?
as im not a mechanic, but a little handy and knowledgable,
id like to go out this morning grab a gauge and all neccesary stuff at once, do autobahn sell t pieces?

ive seen some people remove bungs,
do you run the wiring through the tunnel at the firewall with a bent coat hanger?

There are difficulties in using the center tunnel for extra wiring routing.
After having looked at doing it that way, IMO by far the easiest route for the wiring is along the floor under the carpet between the driver's seat and the door sill.
There is existing wiring there and a large grommet in the engine firewall that is easily pierced for the new wiring - too easy.
This way you also avoid the firewall heat shields.
