does anyone know how to install an oil gauge and a volt gauge? like when to put the sensors and all that, if you do know please respond and let me know, thanks so much, gerry

The oil gauge sensor would normally be installed where the existing sensor is installed using a pipe tee. A volt sensor can tap into the electrical system anywhere almost, One wire to a positive lead that turns off with the switch off, and the other wire to ground.

One advice and one info.

1) use a flexible line not a copper one like I did. Someone here use a braided teflon line and I cannot find same here. Would very much like to know where I could order one online...

2) For the volt meter I used a Radiodhack rectangular meter (about 12$ US) that I mounted inside an audio cassette plastic individual case and that I plug in the cigarette lighter receptable. The recess under the stereo holds it in a stable position. It's maybe not as tidy as a dash mounted meter but it's cheap, easy to install, and you can carry it with you to another car.
