works as it should. installation took about 35 minutes. difficult position during installation, but easily managed even by a bigger guy...
Bought the new DIY Harness for my 2023 RWD Model 3. Installation is easy (though bring some patience and nimble fingers for the plugs). Took me about 1h. If you know what to do it can be done in 20min.
Really does improve the sound noticeably (I'd say a good 20% upgrade). I do not even really feel the need for a Sub anymore. But if a Sub for people with the standard harness would be sold sometime soon, I would definitely be tempted (hint for Hansshow ;)). Works perfectly as of today and really makes listenign to music and podcasts (and even phonecalls) one level better. Imho, best buy for a Model 3, so easy to plug in, everyone should get it!
The harness works great after installation. Not the easiest to install due to the tight spaces and awkward position. Getting yourself upside down on the front passenger seat as show in some online tutorials help you get 2 hands to plug in connector near the glove compartment. Take some patient but it can be done.
Works perfectly
Install was very easy after watching a few your tutorials. Not much else to say except that it works and really makes the front soundstage open up. Works perfectly on my 2023 Model 3 RWD.
I’m happy with the harness. Works perfectly fine. I followed the instructions from the tutorial and everything worked as expected.
Initial reaction was good. But since then, I've heard some static in my newly activated speakers.
