To install the gauge, first remove the trim from the A pillar. I used a
door trim removal tool I got from the local auto parts place for about $5.
The trim comes off easily. I thought the gauge looked best when positioned
low on the A pillar. Both the gauge and the pod are light, so I decided to
attach everything with Velcro. I Gorilla-glued the Velcro on the pod and
drilled a small hole through the trim to feed the wires through. I used
double-sided sticky tape to hold the gauge in position. I kept the tape a
little loose so I could fine-tune the gauge's position after it was
installed.
There's plenty of space at the bottom of the A pillar to feed the gauge
wires through. The yellow wire of the gauge is attached to a circuit with
constant current and the red wire is attached to a switched circuit that
is only hot when the car is running. Constant current is needed because
the gauge needs to remember which of the seven colors you prefer.
