Jahyshow 315Mhz Wireless RF Switch DC 12V 4CH Channel Wireless Remote Control Switch, DC12V Relay Receiver Module, Transmitter Toggle Switch RF Relay (2 Transmitter + 1 Receiver)

No instructions came with it and the instructions in the description are horrible and don't explain how to wire it. I was able to find a similar product with a detailed wiring diagram so was luckily able to get it to work. I'll post pictures of them to hopefully help others. Lack of instructions is why I gave it 3 stars. I'll update later on the quality of the product.

I used this to add power locks to my car and it works great..Little bit of testing needed to figure out the jumper pin setting but only took a few minutes to figure out ..the remote range was poor at first then I stretched out the antenna a little and it greatly increased the range .. Worth the money for many projects u might have. The cover is a bit dinky so I didn't use it cause it is mounted in the trunk anyway no worries of it getting wet or damaged..

No instruction comes with this no Lauren harness just a box with a bunch of connections and no idea how to hook it up when I did figure it out it don't work

Have bought a few of these. Easy to wire, easy to use.

WORKS GREAT

The unit didn’t come with any instructions or diagrams but looking it up on you tube was easy. Pretty straight forward if you have some wiring knowledge.

workes great

The RF link works out of the box. The receiver board uses terminal block connections which makes wiring easier when retrofitting wireless control into a piece of equipment.The product could be improved with silk-screening on the PCB using better identification. relays labelled "A","B","C","D" and the individual relay contacts labelled "NO-C-NC" instead of "A-B-C" for example.
