    You guys don't have to use the hardwire system in the kit. There is lots of options out there.The side power port is an alternative.

    Some have built in Kill switches like the Radenso plugs. The Radenso plugs don't fit very snug. I ordered 12v plugs but they are on backorder too.

    Thanks for adding this information about the power source. This was needed.
    I was going to make a cigarette plug on my own or hard wire it stright to the battery.

    I bought the rear master cigarette lighter charger. Push the red button and power off!

    Gosh for 10 bucks you can get the Chinese V7 detector and keep the power cord and sticky pad. Better value. Throw the V7 in the recycle bin.

    Or market it with some veil

    Don’t forget the power of add-a-fuse. It’s talked about a lot in the audio system world and is great because it’s like a hardwire but turns on and off with your car and Mine is even better because it only turns on when all the electrical is on and not when I’m sitting in a parking lot listening to music saving me some battery life. The TMG has a built in 3 amp fuse so you’re not going to strain anything.

    Since we’re talking about power I want to see the first person to use the detector port in the CPU and figure that all out for us.

    “Add-a-fuse”
    That one you have there is actually the exact type for my car. There’s different ones for different fuses so it helps to pull a fuse and take it in to see what it is. In my car there is a fuse puller in the fuse box in the engine bay but not in the interior fuse box so try there before you use pliers to rip them out.

    @Jag or anyone else that might know the answer for sure TMG CPU.

    Typically wires with the solid white line are positive, but I have a 12-volt wire plug that has a white dash line that's negative. I know what is typically normal but it's not always the case and I don't want to reverse polarized my power so what wire is positive with the hardware kit the black or white dashed?

    I also know typically the fuses on the positive side however...

    I must say I am surprised but the manuals are very basic more so than I thought they would be...

    Well, I wired mine with the fused wire to positive. The CPU works fine and hasn't exploded. :D;)

    That is why I buy a 12v power plug 1.35mm and call it a day :) I realize the manual needs to be tweaked. I will revamp it over the next week. Have any pics what you are working on? The inline fuse is the positive side.@TurboDriver

    thanks again guys for the quick response, I thought the fuse should be positive but wasn't sure in this case, I have a bass ackwards cigarette lighter plug that has the white wire negative so wanted to make sure.

    PS edit. I really need to read the text to talk before I hit send

    The engineers advised me the USB cable I use is not good for multiple heads as the current is to small. The cig plug is just fine.

    I'm using the cigarette plug because it has an on and off button. This can be used as a kill switch.

    @Jag42 - you first posted this one too... is it no longer an alternative? Because I already have a USB port wired, all id havd to do is plug that right into it. But it looks like you deleted it off your OP.... i had screenshotted it earlier for easy reference...

    If you have an old Cobra or Whistler laying around, the power cord will fit the TMG box.

    Neither the website nor the manual list full specs, specifically power requirements. ALP is vague about it, stating 1.5A, but it’s not clear if it’s a fully loaded system or not.

    I would be surprised if those cheap USB 5V to 12V step up cables would provide enough current. In my testing, they seem to crap out past 800mA. If it’s a 1A USB slot you’re plugging into (5V), you’ve only got about 400mA at 12V to work with, and that’s assuming an almost perfectly efficient converter. Even a hearty 2A supply at 5V, if the converter can even handle that, you’re only at 800mA at 12V. That’s enough to run some detectors, but is it enough to run 2 heads? 4? More? And is the cheap converter capable of handling that and providing clean, consistent power at that level? I wouldn’t risk it, personally. Give it switched 12V directly from the vehicle.

    I was advised to not recommend it at all. The engineers said there is not enough current for multiple heads.
    12v 1.35mm plugs from Cobra or Whistler work well. I have ordered a batch of the ones that look like Radenso too.

    This is where I stalled on my 2015 Camry hybrid install. I think I have the heads placed decently and ran the wires. But now looking at how to power the unit.

    Thank you for the tip!
