Testing Wires, What Does Everyone Use?

been installing for awhile now, I'd just like to see what everyone uses to test wires, granted "you should always use a multimeter" is a given, but im sure everyone uses logic probes and test lights too, at least if you want to get cars in and out as fast as u can so you can actually make money.  I currently use a multimeter when i actaully need the number, I have a mac logic probe, and one of those "handy hooker" test lights... is there any new contraptions that makes life easiers when ur tucked on ur back and doing remote starts all day, the handy hooker light is junk, the mac probe is good, but im always poking my fingers, the meter takes 2 hands and takes too much time... anyway if anyone has the "PERFECT TESTING TOOL" let me know and give me model numbers and a URL if possibe??

Thanks, Eric

As for alarm wires and remote starters I would use the multimeter. (always) A quick and easy way to find my tach, I use my logic probe something like one of these   http://buy1.snapon.com/catalog/pro_det.asp?tool=diagnostics&item_ID=16693&group_ID=1393&store=snapon-store&dir=catalog when you find a wire the wire,the tester light  will flash green and red very rapidly almost orange with this tester. this test light has a resistance of 10 milliamps at 14 volts. A bit safe.

And for car audio behind the deck installations I use a regular test light. And for those people with chopped off harnesses, I still use my multimeter to check for speaker resistance.

But 80-90% of the time ill use my headache safe multimeter. My multimeter is my troubleshooter.

I use "The Probe" it is so handy i dont know how i got by without it. You can look at one at www.matcotools.com and its Part#: TL1C
