The Ace

OK here's the deal: I'm going to install a multi-meter (in/outside temp, electronic voltage, boost), and I would like to also rig-up a multi-switch, so that I'll be able to measure the voltage from different sources.

So, besides the battery, the boost sensor and the fuel pump, what other voltages should I wire up to my voltage meter ? Does the MAF produce a measurable voltage (in order to know how much air I'm getting) ?

Any ideas fellas ?
