I'm using oil pressure and voltage.......Back to the basics.
Here's the info I had put together.

The pod fits great w/ a little help from the heat gun. The one to
order is Autometer part no. 20-428 for a '96-'98 Honda civic 2dr.
Go to www.autometer.com for all the gauge styles
I got my pod and gauges from www.carparts.com. .
I used Autometer Gauges. Their “Z” series because I wanted an all black look.
Any of their 2 1/16 styles would work.


Modifying the civic pod to fit the VX is easy. I just trimmed the rib on the inside
top and bottom of the pod, gently heated it on the inside w/ a
heat gun and pressed it against the trim. I did the top first and then
the bottom. Just be careful around the top because the heat gets
channeled through the top opening, which is easy to distort.
You need to be careful. It’s easy to ruin a pod with too much heat.
And get burned trying to press down the pod flange. (Use a thick glove)
You have the choice of painting the pod gray or the whole pillar black.

Thought I might let you know what I went thru on the oil press sender.
My OEM sender was in the lower forward hole and there was not enough
room (clearance for the large dia of the new sender) for the new sender in
the upper aft hole which had an allen screw plug.
So I moved the OEM to the upper aft hole, and then put the new sender where the
OEM sender had been. It was the same thread but I had a hard time starting
it, trying to make sure I didn't cross thread it. I also noticed that it
looks like there is an extra wire in the wiring harness at the OEM sender. I
suspect it’s for models that have the oil press sender. Couldn't find it in
the dash area so just ran a wire on to the new sender.

E-mail from Jim Catterson:
Reg, after you emailed me that the sender was a bitch to get in, I
did a little investigating...the sender threads are not metric, nor
are they pipe thread [this means that they taper very slightly]. You
only notice the difference when you thread the sender into a metric
die. The 5mm allen holed plug in the filter housing is the metric
equivalent of 1/8" pipe thread, having that very slight taper. I took
the plug and matched the thread to the smallest metric die that would
fit and then ran the die down the sender's threads. The sender is
brass so the threads cut pretty easily. It still threaded-in somewhat
tightly because of the pipe thread, but I definitely wasn't cutting
any threads in either the housing or the sender...
