I'm hoping someone can help me out here. I'm thinking about purchasing a zw5 for my vehicle, but am not sure about the install process. You see, the Hynndai Ioniq doesn't have a 12v battery, so what other option do so have to connect the interface to a power source? Any information would greatly be appreciated. Thanks!

While I'm not super familiar with the ioniq, I would have to imagine the entire car isn't running on 240v, so there is likely a 240 to 12v converter in there somewhere. So the best option for an easy install would be to find a 12 v circuit and use an "add a fuse" or fuse tap at the fuse box to give you a 12 v source. The question is does the fuse box under the hood presuming there is one have any 12v options or is it only an interior fuse box, you might have to get the power wire for the zw5 through the firewall (it's a small wire so it won't be that hard to do). Depending on where in hawaii you are, I think it's mostly laser, so this might be the more important countermeasure.

I appreciate the response. One of the many reasons I was asking is that I read this on a forum "Many modern vehicles only supply enough power to their circuits to operate the vehicle's functions. Even if the detector/ZW5 powers on from a fuse box connection, they may lose power when there is a larger drain on them, such as during an alert and while shifting". If this is not the case, I will go the route of tapping into the fuse box in the engine bay. I have to say, I thought I was going crazy when I couldn't find the car battery. It was until I did some researched and discovered that Hyundai elimintated the traditional battery for this vehicle.

I've tapped fuses on all my vehicles running a bunch of dashcams, Rd's and laser jammers and never had an issue. Certain high end cars have highly monitored circuits and will fuss if there is excess drain.... In that case I'd tap the accessory circuit that runs the cigarette/12v port since that is expected to have varied loads.

Looking at a version of the owners manual for the Ioniq, it does appear as if there are two fuses in the lower right hand side of the box labeled “Power Outlet” and appear to power the Cigarette Lighter and the power outlet. Both show a 20A rating. If the only other device you have in your cigarette lighter is a RD, you should have sufficient amperage for the shifters, as I believe the inline fuse for the ZW5 is 10A (might want to confirm with Escort, as it’s not called out in their online manual).

Awesome, I truly appreciate your responses which were very helpful. Now, part two of my question. What would be a good spot to put the laser jammers? I was going to put it in between left and right of the Hyundai emblem, but as you can see by the pictures they are shutters that open and close. I'm trying to figure of an alternate location. Once again, I truly appreciate all of your help and knowledge on this matter.

Have you looked at the back of your car? :) I am not kidding - my 2017 IoniQ Hybrid had a 12V battery in a luggage compartment. Although, if I am not mistaken, the 2018+ models got rid of lead-acids completely. I run a 2020 IoniQ Hybrid now - no external battery.

You wouldn't have any problems with tapping to a fuse box. I run R7, a dashcam and a phone in a charger, in addition to a regular multimedia player, and the car doesn't have any problems with keeping everything powered and recharged, including the Li-Ion 12V built in battery.

I don't know about the fuse box in an engine compartment, but one under a steering wheel has two auxiliary fuses that you can tap on. One is 10A, called "SPARE (IG2)" (just under EEWP), and it's powered when you turn your ignition on. Another one is 10A, called "SPARE (B+)" near from the bottom left, and is always powered on. I used the "(IG2)" one to hardwire my R7.

Thanks for the advice. Now I'm trying to figure out where to put the sensors since the grill has vents that shut and close. I wonder if I can put it on the bottom opening, or if that is to low and reduces the chance of being effective against lasers.
