Verified Purchase(What's this?)
This review is from: Escort 79-000041-01 Direct Wire SmartCord (Red Light) (Electronics)
The guy below me, Norman, said exactly what I wanted to say about the product. It is a bit expensive for the simple circuitry (I should have just made one as a EE major...).
The only thing I want to note is that if you are buying this, you need to access your car's fuse box. It's rated at a certain current rating (I can't remember what, I think its 10 or 15 amps), which means you need to find an open slot for it to work it...
... If you are like me, and may not have any open slots with this requirement, you'll need one of these:
That is called an "add-a-fuse". It will allow you to plug that into a fuse slot, and piggyback it for your hardwire setup (this way, you don't void any warranties). This is a less than 5 dollar buy at most hardware stores, I know pep boys has them. It's worth it to check out your fuse box before you buy, so you can have all the components in-hand when your setting it up (which should take you 5-10 minutes, depending how you want to cleanly run the wires).
