So I’m installing a new stereo system in my 2011 F150. I’m running into an issue though with the ignition wire. The stereo requires 12 V to power through that line but I’m only getting 2.5 V. I contacted the support for the stereo and they said that my ignition wire should be controlled by canbus, and that I may need a decode adapter to convert my truck’s ignition wire signal to a stable 12V power.
The problem is, I don’t know the first thing about canbus or decode adapters. I did some searching online and it seems a bit trivial to me that installing this box will solve all my problems. Does anyone have any experience with this? I’ve also seen some people splice additional wires from other things that might have the 12 V of power, but usually that ends up disabling something else in the truck so I’d like to do it right the first time. Any suggestions?
The cord from pin 15 in the main stereo plug is labeled as "Voltage supplied at Start overload protected", so that's the one I connected to the red wire on the aftermarket harness for the ignition wire. But it says in my stereo's instructions, that this wire should be pulling in 12 V in order for the stereo to work properly, but I'm only getting the 2.5 V. I could run a dedicated wire from the battery. I've never done it before though. Would you run it through the fuse box under the glove box? And how can I set it up so that the 12 V only sends when the truck is running? I'm just looking for the simplest, least destructive method of getting the 12 volts.

You need to use the canbus adapter for your switched power. The rest of the wires on the canbus adapter should match the wire colors on the new stereo wiring harness. The harness you currently have won't work
That new harness worked pretty well! It's up and running. Bluetooth, Apple Car Play and backup cam are all working fine. The only thing I wasn't able to get working was the steering wheel controls. The stereo has a way of learning each button, but it errors out each time. I'll have to play with that a little more. Thanks Wyo11Scab for the confirmation on using the canbus adapter!
Canbus & Decode Adapters???
