As more new vehicle components feature coaxial (COAX) cables in high frequency applications, including cellular and GPS antennas, Wi-Fi, and image display cameras, a new kit has been released from GM Tools and Equipment for testing coaxial cables. The EL-52552 COAX FAKRA Cable Adapter Kit (Fig. 21) can help in diagnosing a variety of coax cables, including Wi-Fi, cameras, headliner cables, A-pillar cables and more. Diagnosing coax cables routed through the headliner, for example, is made easier with the kit.

The EL-52552 Kit covers all known cable configurations equipped with FAKRA (Fachkreis Automobil, a German standard) connectors. The adapters included with the kit are designed with universal FAKRA connectors, Z Code, in order to connect to all color coded FAKRA connectors on the coax cables in the vehicle.
The current method of end-to-end testing is to connect three or four DVOM test leads together. Using the adapters in the kit allow a connection to one end of the coax cable (with resistors) connector and having to only probe the other connector end. Banana jacks enable the use of the terminal adapter kit.
The test connectors have built in resistors (both male and female FAKRA universal connectors). The resistor values are set for error proofing: green color code – 51 Ohm NOM; orange color code – 300 Ohm NOM

I found a call to use this kit in DOC 5026158 but it did not say what adapter to use.
Where are the instructions on how to use the coax adapter kit?
