AL Priority power supply

[whats up]

I want to install the AL Priority with Bluetooth and 2 front sensors in my cayman. I have a spot that I can put every thing in a waterproof box. So I don't have to snake wires through the firewall all I need is power. Can I hook It up straight to the battery. And if so how and what will be needed.

Thanks for the help

If you connect it to the battery, there's no practical way to power it off. I don't think you want it powered on all the time, around-the-clock. You'll need a switched 12V source somewhere.

I thought the system can be turn off from the Bluetooth mobile phone connection.
If not that would be a problem with the install. Because there is no fuse box from what I can see just the battery.

I just chatted with a friend of mine who has owned every model Cayman. He's on his 3rd one. He's a mod over on the Planet 9 forums. You may want to cruise over there and ask for ideas, too.

He tells me no fuse panel in the front boot.

I haven't tried turning things on/off via bluetooth. Others here can chime in on that! Good luck!

Don't wire it to the battery unless you want to end up with a dead battery if you don't drive the car for a few days to a few weeks.

You can't turn it off via BT. Think about it. If you turned the system off via BT, how would you turn it back on if it's powered off?

Well, you could install a giant toggle switch on the hood...

Of course the system can be turned on and off with BT but the CPU will always still be drawing some current so the BT connection can stay active while its looking for the turn on signal over BT. While this is not a full draw it can overtime cause your battery to drain and it should be connected to a switched power source.

I would go this way : connect the ground wire to the negative of the battery , then for the positive i would draw a wire from the
one of the front headlight , either you find the right wire from the bundle or you can solder a needle to end of the wire and insert
it in the socket holding one of the position lights.

The wire can be quite thin , so you dont need to make hole to reach the lights inside the cluster .

Seems complicated but in fact it is very easy when you get the idea.

For protection you can install an inline fuse on the negative or positive wire. 2 amps fuse is plenty.

Make sure the box you will use is not only waterproof but will be placed where no condensation
could occur , otherwise , over time the moisture is enough to degrade the metal\connections inside
the Cpu. I realised that when i checked the cpu from a m27 blinder which i placed inside the motor
bay ... all rotten inside after 1 year due to winter causing large change of temperature , -20C then +20
as the car was sleeping in garage.
Good luck.

I have a 2014 911 Turbo, and in my car there is a very accessible opening going through the firewall above the driver footrest and left of the steering column where it passes thru the firewall. The opening is plugged by a plastic cap you can easily remove/replace.

I would look for the same thing in your Cayman. The plastic trim in the front trunk under the windshield should snap out easily for access from the front as well. Run a wire thru the opening to your fuse panel, then use an add a fuse on a switched fuse location.

Should be easy to find a ground screw in the front area.

Any advice for wiring it to the fuse box? I have a 2016 Mazda CX-5 that I'm installing the ALP into. I looked at the Laser interceptor install on my 2013 GTR for inspiration. The professional install had the power wire plugged into one of the fuses switched by the ignition.
When I try this in the CX-5 I can't get it to work. With the wire connected to the unswitched side of the fuse box it powers up and works fine. When I plug into the switched side of the fuse box it works with the ignition on (ACC mode, engine off), but when I start the engine I just get a solid green light and the controls won't work. Not getting enough amperage? Is there a way to build a relay into the unswitched side so it powers on and off with the ignition?
