Apparent RF/EM Interference causing TPMS and Key Fob to not function properly. I am going crazy.

A few months ago I splurged and DIY installed a bunch of peripherals in my Tacoma. I have since been trying on and off to pinpoint the source(s) of an unspecified Interference ( assumedly RF/EM, ) that has been causing the TPMS and Key Fob to not function properly.

I am certain one or more of these recently installed peripherals are the culprit, because the moment they are all powered down, the interference stops. I know that the Power Supply ( Gold, ) and the Power Supply Charging Lead ( Red, ) are infact NOT the culprit, because with only these things running alone the interference is not present at all.

I wanted to seek some advice from anybody who might have experience with this relatively niche predicament I have gotten my self into before I go tearing everything apart that I spent weeks neatly installing and hiding away from sight. :/

In your opinion, what is likely causing the most interference to the Key Fob and TPMS? What's the best way to reduce the interference without sacrificing peripherals? Please note, the Dash Vameras are a must keep as my Truck has been hit 4 tmes while parked and I was away ( they run 24/7, ) and the LED Displays would be preferable to keep as they broadcast that vehicle is monitored 360° 24/7, but are lower priority than the Dash Cameras themselves. The LED Light Bars are the lowest priority to keep as they are just for aesthetic.

I have drawn up and included a rough but fairly accurate representation of how all the peripherals are installed.

* Yellow are the Vantrue E360 Dash Cameras, Lime Green are the Generic LED Displays, Magenta are the Generic LED Light bars.

* Sea-foam Green is the USB HUB, Gold is the Power Supply, Red is the Lead that charges the Power Supply via the Vehicle's Battery, Pos/Neg is the Vehicle's Battery.

* White is the Cable Management Rack ( inert in of itself, ) Blue/Cyan/Light-Brown/Dark-Brown are the power cables for their respective peripherals.

 

I would start with anything LED as cheap LEDs are notorious for making RF noise.

 

Get yourself a tiny SA.

you can set the frequency to span between 400-500 MHZ, then you can sweep
Around the vehicle to see where the interference is coming from.
