There's a trick to the wiring. It's different than the instructions. It's listed in he review below. Very easy and works well. You just have to use different instructions to wire it.

I bought the PL-SW29 to remotely control four different accessory lights on my car. Some I had to activate using 12v (+), some I had to activate using a ground (-) signal, and the PL-SW29 can do both with ease. The instructions on the back, as mentioned many times in other reviews, is very vague. However here's a proper wiring instruction/guide:
RED - 12v (+) Power
A. Connect it to a 12v (+) switched ACC (accessory) line (cigarette lighter, etc). The PL-SW29 will only work if you have the key in the ignition and the key is in the ACC or ON position; or
B. Connect it to a 12v (+) CONSTANT (direct to battery positive) if you want to use the PL-SW29 at all times, even with the car off.
BLACK - Ground (-)
connect this to your battery (-) or to the chassis.
Now then, there are 4-channels to control with the PL-SW29, and there are 4-pairs of wires - 2 per channel:
- Grey pair for channel 1
- Brown pair for channel 2
- Blue pair for channel 3
- Green pair for channel 4
Each pair of wires can be connected in-line with an accessory, or can be connected to provide either power (+) or ground (-) to an accessory to turn it on. Each pair of wires are also interchangeable with each other; that means that there is no specific "input" and no specific "output" wire per pair. Note that the PL-SW29 does NOT directly provide 12v+ or ground for an accessory; there is however a very easy solution to this, as I'll explain below.
We'll use channel 1 (grey wires) for this example:
Let's say you have an accessory that needs 12v (+) to turn on. To wire the PL-SW29 you would connect one of the grey wires (which becomes the "input") to the PL-SW29's red "power" wire, and the other grey wire (which becomes the "output") to the accessory's (+) wire. Hit the remote channel 1 button and the accessory turn on. Hit the button again and it will turn off.
The same goes for grounded signals. We'll use channel 2 (brown wires) for this example:
Let's say you have an accessory that needs a ground (-) to turn on, connect one of the brown wires (which becomes the input) to the PL-SW29's black "ground" wire, and the other brown wire (which becomes the "output") to the accessory's (-) wire. Hit the remote channel 2 button and the accessory should turn on. Hit the button again and it will turn off.
Thus, each channel can be wired to control all (+), all (-), or any combination of signals to activate any accessories - provided that the accessory requirement is no more than 15 amps. Anything that draws more than 15 amps will blow the PL-SW29's built in 15-amp micro relays.
Also, if you want "momentary" operation (accessory stays on when you push and hold the button, but turns off when you let the button go) you'll have to open up the PL-SW29's case (4 small Phillips screws on the bottom) and remove the jumper for that channel, as shown on the diagram on the back of the packaging.
The range of the remote varies by the surrounding environment, the location of the PL-SW29 antenna, and the length of the PL-SW29 antenna. I have my PL-SW29 mounted underneath the passenger seat, so its antenna wire was low and underneath the carpet. With that setup I had a range of about 100 feet in an open, obstacle-free parking lot with the remote controller's antenna extended. However, I added another 5 feet of regular wire to the end of the PL-SW29's antenna, and ran the now longer antenna wire up behind the car's A-pillar. With this new setup I have about 250 feet of range with the same conditions.
All in all once the installation procedure is figured out, the PL-SW29 works good. It doesn't cost much, the remote is decent (though I wish it didn't have an old-school telescopic antenna), and so far it's performed as expected.
