Remote Boot Unlocker

[The1985divo]

I want to be able to use the second button on my alarm to open my boot, is it just as simple as putting a wire to a certain place or easier to take her to the auto eleky?

Assuming your remote's 2nd button triggers an event in your receiver/control unit, i.e the other end that's in the car, you'd generally find an output on the control unit that you can make use of.

Hook the output through a relay to supply a 12v level when active. Splice this into the wiring that heads back to your boot release and you should be right.

(Depending upon if your control unit has an active high or low, you may need to invert the logic to drive the relay- most are active high though.)

Hold your horses there!

Check your alarm before you do this. Alot of alarns have a negative boot release trigger rather than a positive you could start blowing fues or stuff your alarm.

If it is a negative trigger you will need 2 relays to make it work to change the negative switch to a positive.
Hook the first relay up with positive and switch joined, earth to the negative output on the alarm and output to the second relay switch input. continue to wire the second relay as normal.

If you have a positive output I suggest you hook it up through a relay so save burning out anything in your alarm, I run 30amp relays on my boot release and yes mine is negative output. It took a while to work out how to solve it.

This can be done with one relay. Why are you using two?

From what I can make of it, you've got the second one there for no reason b/c the output from the first one is positive anyway.

Please correct me if I'm wrong.

Personally I'd use a switching tranny to do it if a level inversion was required - but heck, I'm holding my horses!

I forgot to mention I still run the button inside the car and I run it through a relay, It made a huge improvement to the boot opener. I supose if you didnt run a relay for the normal boot open button you wouldnt need it.

side note - a new boot latch helped my electric boot opening probs
