Ohh by the way Thanks for all your responses...
I am not too sure about the oil pressure gauge, but with the other gauges, you have this backwards. Mecahnical gauges require you to tap into the existing line (or whatever depending on the gauge). Electrical gauges require the same plus they require you to tap into an electrical supply.
For instance with the boost gauge using the Defi electrical gauges (expensive but very good and accurate), you have to tap into constant hot, hot with ignition on, illumination, and ground, then you have to tap the sensor into the BOV. With the boost gauge using the Autometer mechanical gauges, you only need to tap into hot, ground, and BOV.
I bought the Defi electrical gauges, and I think that they are awesome. They have a 2 minute record, remember peak, have a warning light, and are very accurate. These are small features that are pretty cool.
If you do go electrical, tap into the wires mentioned above using your clock. Each wire is labeled on the back of the clock. If you go mechanical, then you can also tap there using ground and illumination.
No problem and have fun installing.
