It should be, we put which Harness to get for which MICRO-START in the Listing. Meaning it will say Clampless Harness for XP-20 in the Listing Title. So I bet you saw that and your good. Thanks for supporting Antigravity!
Just be sure when you route the cable to watch out for the Hinges on the Frunk passenger side. Pretty self explanitory as you do it but you don't want it getting pinched as you route it.

Detroit, make sure you do not have the wiring going to a non-keyed fuse... meaning to something that provides energy all the time, when the key is off it should turn the accessory off. Secondly, if Porsche didn't do it themselves they will blame it on that and with good reason. There are so many hacks at the stereo and radar installation places that don't understand the wiring on Porsches, and if you end up creating a higher than normal parasitic drain your taking a big risk with the Porsche Lithium Battery. Any accessories add parasitic drain if not wired correctly, and Porsche are very sensative to voltage also. And yes if the Radar detector is connected incorrectly it could create a significan't parastic drain even though it seem like a small device.
