GE TPL Jumper and Extension kit SPK-216 cable adapters for mobile radio

Description

GE TPL Jumper and Extension kit SPK-216
This sale is for the cable adapter kit and hookup diagram.
No computers, test equipment, or other junk pictured, is part of this listing.
The cables pictured are the cables you will receive.
This item is double boxed and ready to ship.
I have a day job, so 2 day handling is listed in the event I have a busy day.
Most items ship the next day.
What is it:
I have no earthly idea.
What I can say is that it was likely used for bench testing and troubleshooting some sort of two-way radio.
It would have been handy to have a list of compatible systems it works with, but that did not happen.
Condition:
Used. Given that everything is clean, the previous owner appears to have taken care of them and even returned them to their original box when finished.
One RCA female connector is missing its isolator, but otherwise the rust and humidity haven’t hurt things much at all.
GE part number SPK-216
Warranty and returns:
Returns are not accepted as I have no way of testing these cables and, much to my embarrassment, I taped up the box before I realized I could test the wires for continuity.  Be VERY sure you want this cable kit before you purchase them.
It is a specialty item.
Shipping:
Shipping within the United States will be by, FedEx Ground, UPS ground, or USPS Priority Mail.
The cable kit box is double boxed with enough bubble wrap and / or foam to protect it.
I will only ship internationally, through eBay's global shipping program.  Please do not ask for other international shipping options, as I will not respond.  International buyers are responsible for international postage, import duties, taxes, etc.
Local pickup is always an option (and encouraged).
