How to install an aftermarket gauge in your Phase I dash
- The gauge you wish to install
- Rubber band (usually included with gauge, at least with Autometer)
- Shoe Polish
- Razor blade
- Hole saw, size depends on size of gauge
How To Do It
The dash material is just a hard plastic covered with foam padding and a vinyl covering on top of that. First mark the center of the area that you wish to place the gauge.
Measure the diameter of the BACK of the gauge, so that it will sit inside the hole with the lip holding it from falling in.
Carefully, but with a high-speed drill so that it cuts through the vinyl, instead of ripping or pulling it, cut a hole straight into the dash. Then you will want to ream it out with the razor so that it is smooth.
Follow the instructions included with your gauge to get it properly wired up.
