I'm headed over to the race shop tonight and will look to see which one it is.
Garrett, what are you using the cable for? Are you looking for a download cable? Are you looking to connect a Smarty cam to the Dash? If you describe what it is being used for Matt can tell you what is available and what you need. And I am sure his prices are better than your local race shop.
If you are looking for a download cable, there are two types. One type goes directly to the dash and the other type goes to a car mounted download port.
I'm looking for the cables to connect to the AIM port and the ECU port to a PC. See the attached pictures.
The cords you are looking for are only available through Radical (to the best of my knowledge). You may want to call around to several Radical dealers because they all have different cost structures and different prices on Parts. Lately I have been having good luck with Radical Northwest but shop around.
Here is a picture of the cord options for downloading data. The cord on the left is available from AiM and plugs directly into the Pista dash (not sure if it plugs into the MXL2), the cord in the center is used to download AiM Data from the car (both of these cords pull the same data), and the cord on the right is used to download the ECU data.
Also your Data socket appears to be missing a nut. This is what it looked like on my car.
Another possible option is the USB bulkhead connector for the dash. I know Radical had some custom harnesses, so you would have to check that you have a plastic 4 pin female Binder connector marked USB. If you do, you can attach that to the bulkhead adapter and use a regular USB mini cable.
@eugeniobolo, that is a cable that all Radical dealers keep in stock and they cost ~$160. Please consider contacting one of the Dealers that are Registry sponsors. There is no aftermarket cable available that I am aware of so a Radical dealer is the only option.
