Please don't quote this entire block on this topic, it will just make a big mess of things. I am providing this information to help prevent you from releasing the magic smoke from your expensive equipment. However, what you do with the info that follows is done at your own risk. I take no responsibility for your actions, that is your job. I have been asked on occasion to provide a cable with which someone can connect a SFA1 or FL2 adapter to the handbrake port on a set of Clubsport or CSR Pedals. I have done this several times now. On one occasion I provided a few cables that would allow a person to use their Fanatec sequential shifter as the handbrake. (digital on/off) As well, I have seen many people ask just what the connector is, etc. There seems to be some mystery surrounding just what the handbrake port on the PCB can do... As well, not every CSP PCB has this port... So before you get your hopes up, you should check. Well, the connector that fits is called a JST ZH style. These can be purchased very cheaply, along with the crimp terminals that go in the plug. The problem lies in the necessity for a tool to crimp the terminals onto the wires. This tool is at minimum, $54 US. That makes for a pretty expensive cable for a DIY project. I am going to put more details in here as I go along, but for now I will go over some of the basics. What does the port do? I have seen some misinformation about this board that needs clearing up... The handbrake port is recognized as ANALOG in the Forza series of games. So if you connect a pot to the handbrake port and turn it, the handbrake is variable from 0 to 100 percent. The handbrake port is recognized by Windows. However, it does not show up on the Fanatec properties page. This does not matter... If you go into a game, you can map it to something. Connector - (plugs into board): Rather than bothering with giving you the model number of the connector, etc. Pre-made cable assemblies with connectors attached are available via Ebay, just search for JST ZH 4 and you will find some. You need 4 pin connectors! I will search for some others places. Connector on the CSP Board: (not my photo, just grabbed from google and added the pin numbers for reference) The pin connections are as such: 1 - Positive 3.3v 2 - Signal into the board 3 - Ground Leave the 4th pin disconnected... The handbrake port reads an increase in voltage on pin 3 as an increase in handbrake level. This is different from the other ports on the board. For example, if you connected pin 1 directly to pin 2, that would give 100% handbrake. Examples: (using quotes on these just for the sake of separation) More info to follow, I just wanted to get this up here as a start... I will edit to add more later. The format of the above is probably subject to change as I add info as well. I may end up moving this to my website later.
