Preparing the Plastic
This part can be
dangerous to your health! Exercise extreme caution!
The face-plate on the RJ12 female
throttle jack has a raised edge. If we were to install this into
the module, we'd cut into a lot of the width and depth of the edge of the
module. We might also weaken the module. Our first step is
to remove and trim this raised edge so that it fits flush into the module.
Our photos show the process for a single-plug jack. The process
is the same for a double-plug jack.
If it's necessary to remove the female
plugs from the jack, a good twist-and-pull will snap each plug out of the
To protect the surface of the faceplate
from scratches, tape some masking tape over the front of the faceplate.
We next trim the raised edges of
the faceplate so that the jack assembly (faceplate and female plugs) are
flush with the side of our module. (Take a look at the photo below
to get a better idea.)
Place the faceplate on a sturdy working
surface so that you are looking at the underside.
Use a very sharp and sturdy utility
knife, Cut the raised edges of the plastic faceplate. The knife
should easily slide down the raised edges.
Don't try to cut the plastic in one
stroke. Follow the salami method and use repeated strokes.
Keep your fingers away from the knife blade!
There are two screwholes in the faceplate
with some raised plastic lugs on the underside. Take your favourite
flat file and file off these plastic lugs.
Push and snap the female plugs back
into the faceplate.
You should now have a jack assembly
that looks like the one on the right side of the photo below.

female jacks! These are "before" and "after" photos.
