Plan on using this to activate an existing door lock switch in my old Jaguar, Do I need a relay for this purpose?

Depends on the amp rating of the electric door locks. This remote relay is rated for 15amp service .. If the door lock are higher than 15amp then you will need to use the remote relay to activate another relay rated for the higher amps if need be.

no relay is required. My shop guys installed it with no problems direct to the power source

I did not use a relay. I used 16g wire. All I did was tap into my reverse light wire from the bundled trailer connections near the hitch. I hope that helps.

As a novice at electrical things, I really don't know the answer to this about wiring. I just followed the code, ups and downs, inside my old remote which was taken from inside the opener. I do find the range less than the old one, but I would rather be safe and not open the door too soon! Great item for the cost.

I used the relay and did not cut any of the original wires when I installed these. I used the original horn harness to trigger the relay. The original connection on my car was a simple press fit spade connector, so it was easy. If your car has a fancier connector it might be more difficult to avoid cutting some original wires.

It will work if you have terminal wires going from your garage door opener to a switch. This unit will simply act like the switch.

I interposed the device between the power source and electric plug for the garage door lifter motor and inserted the two wires into the device(hot vs ground)according to careful review of wiring instructions. This arrangement works as an ON/Off switch activated by the preprogrammed remote. My setup worked quite perfectly! Thank you! Pan

The relay card is just transistors driving the relays- takes 2-12V on an input to activate the relay. There is no programming that I know of and no setup buttons.

I use it for my garage door as a relay on zwave. It sits out in the open on too of garage door motor. Good luck. Its very simple

I am not using a relay and haven't had any problems. It works just like it should using only a switch.

Hi Jake, you will need the wiring kit which contains the relay, the horn voltage is too much for the horn switch and you must use the relay, its not much, about 12 bucks,iirc.

This is a simple switch, it has no idea what model you have, and if it was capable of thought it wouldn't care. It simply completes a path for a low voltage circuit with an open point in the middle. Push the button and it lets a dc voltage make contact with the second terminal on the opener, which will either close or open it. It knows what to do. Its ten cents, and will also work as a doorbell button.

No. Relays are recommended when device draws considerable amount of amperage. The dome light draws very little amps therefore relay not needed. Installed mine in Polaris Ranger and works great.

I had to use aditional relay for the signal lights when I unlock and 2 rectifiers. If you are not good with electronic best way to get auto electrical guy

No, it is not necessary from an electrical standpoint. The button runs on a low voltage system, hence you will not get shocked. However, you could inadvertantly activate your opener by touching the two wires together or pressing the button while tightening the scews. If this is a concern you could unplug the unit first. Hope this helps.

You could wire up switches to control each relay. You would supply 5 volts to the corresponding pin for a given relay you want to activate via individual switches. But the best use for this board is to let an Arduino or similar micro controller operate it. That is its intended usage.

You need 2 relays to make whole system work with your alarm. Here is the diagram to wire it up. http://img35.imageshack.us/img35/2607/powerdoorlockwiringfour.jpg
