This model is designed for an itegration of all necessary material to get FPV video stream from the car:
The camera is plugged to the VTX with 3 wires.
The VTX is powered directly on the 3S LIPO battery from the car. Optionaly you can filter the signal from the battery using this:
Caddx ratel 2 FPV camera:
I use the VTX (video transmter) Rush tank ultimate plus:
optional: you can replace the antena cable coming with the VTX with this one (on the picture I use the original one and it works fine): SMA F90 to MMCX M, 5CM
Use any antenna with SMA connector
Use any analogic FPV receiver (I started with a USB receiver connected to my phone till I got some goggles).

Other advices
I use this small device that is plugged on the battery diagnostic connector (the one not used when you drive the tarmo5). It indicates the voltage of each element of your battery and you can set an alarm to protect the battery from low voltage.
