Welcome to the forum. Did you look in the Owner's Manual in the MyPorsche app?

 

I’m amazed too.
My owner’s manual has this information, as does GTK App (Retired) and My Porsche App.

 

The OP is not wrong. The fuse plan is not provided in the 2024 Owner's Manual nor in the My Porsche app for 2024 vehicles. I just checked both.

 

I used this one for my 2025 718 Boxster.

Thanks, found one on-line too, but just surprised one is not included in the manual or the fusebox itself. Hoping to find one that I can print and add to the manual.

 

When installing my detector (escort) I bought one of their cables that plugs into the ODB2 port. In the past I've wired to the fuse box. This was just much simpler. If I need to plug in my launch scanner l unplug and plug back in.

 

It’s in the Drivers Manual section of the My Porsche app. Just search ‘Fuses’. I’ve just looked and it’s there it just doesn’t give it in diagram form but as a list.

 

You have a 2022, according to your garage. This is no longer true for the 2024 edition.

 

Check the app for an update. There was one for iPhone yesterday that changed the manual for me.

 

I have not been able to find the rear trunk fuse / relay assignment map for the GTS 4.0L. Not the front fuse blocks, the rear one is by the right side of the rear trunk after you pull out the side carpet. Does anyone have info on that? The ones I've seen online are for the 981 models. The 4.0L has different electrical connections in the back. Thanks!

 

This just pisses me off. As others have mentioned, my 2025 GTS owners manual just says not to touch anything electrical and to not mess with fuses.

I’m looking to hardwire a dash cam, I need one ACC slot and one always on slot. In my drivers side fuse box I have empty slots at B7, B9 and D1. Does anyone know how those slots behave? I can poke at them with a voltmeter, but it sounds like some circuits turn off after a half hour and it would be nice to know if those do that.

 

I think for ACC power, your d1 (rear wiper) could be a good one. I'd just tap into existing function fuses, like the alarm horn might be on all the time. PS. I'm just guessing, have not tapped into any power yet. Good luck!

 

I think your suggestions are very good ones, that’s likely what I’ll do.

 

I've been trying to figure out how to manually turn on the engine airflow fans (the ones behind the side intake scoops). 981 has the relays in the rear trunk fuse block. But I can't find anything similar in the 982 4.0 setup. Anyone knows? ☺
