I had an interesting experience with "TireTracker" monitoring system. Last April I purchased this system with 12 sensors. I mounted the monitor up near the original tire monitor and spliced into the 12v power. My mistake. The unit is suppose to only plug into a cigarette lighter because the male adapter reduces the voltage going to the monitor. To my surprise, the company replaced the monitor at no cost even though it was my fault. I did the same thing with the Rand McNally GPS with the same results, but they repaired it under warranty. Some times you just luck out.

Good point Chester,
When I'm permanently mouning a device that requires a voltage reducing plug I mount a female plug under the dash and hardwire it into a 12V source. A multiple inlet plug would be a good idea. It's easy to route the power wire to the hidden plug and avoid having the male plug visible. A wire tie or electrical tape can help avoid vibration induced disconnect.

That's what I did, have a 3 port 12v outlet inside the center console hard-wired to a 12v source. Runs my GPS, XM radio, and gives me a spare. That reminds me that I have to clean up the rats nest in there.
