Hacking a Fanatec Speedster 3 WheelI want to mount the wheel in my cab flush to the dash. With a little encouragement from markvp's Pole Position project, I decided to take the plunge. Ultimately I needed to remove all functional components from the housing then come up with a way to mount it into a flat dash board. This write-up describes the steps involved in dismantling a Fanatec wheel.
Remove Bottom Plate
The bottom section is held on with 11 Philips head screws. Remove all screws and remove the cover.
Mark Connectors
There are two PCB's inside, each with lots of small connectors. Using a Sharpie pen, make various marks on the connectors and their mating sockets. I sometimes did one line, two, or three. Sometimes on the corners, sometimes on the long edge, sometimes on the short. Just make them different. I made a mistake by not marking the plug portion. When I removed my first plug, I noticed it was not marked. I had only marked the PCB and socket. Make sure to bring the pen all the way to the top (near the wires). BEFORE YOU REMOVE ANY WIRES, take a couple of pictures, from different angles. This way, if you can't figure out your markings, it will help in the re-assembly. Also, make sure the pictures are not blurry before you proceed. Using the macro mode of your camera usually helps for pictures like this.
Remove Connectors
Gently remove the plugs. Some require a little persuasion, but they do come off. I had the best luck by just grabbing it with my thumb and forefinger and pulling up while wiggling. With all wires unplugged, you will need to cut a couple of larger wire ties to separate the wire bundles. The picture only shows the green PCB, but you need to mark the wires and remove the connectors for the brown PCB as well. I left a few connectors on that go to other components not associated with the main assembly.
Remove Wheel
The wheel is held in place with one large Philips head screw located on the bottom side of the steering wheel, where it goes into the housing. Remove this screw. Gently wiggle the wheel while pulling it off. Once it initially separates, feed the wires through the hole as you pull the wheel. Do not pull too tightly or else you will break a wire or connection.
Remove Main Assembly
Removing the wheel exposes 4 screws that hold the metal housing in place. Remove these screws and the main assembly comes off.
Rumblers
There are two rumble motors mounted in the wheel. You do not necessarily need to get at them, but if you do, you remove the silver ring, then three screws behind that, then the two green strips on the bottom portion of the wheel. The center plate can now be lifted. The wires are kind of tight so don't lift it too high. I was initially disappointed when I didn't see the rumblers when I removed the bottom. I'm planning on mounting a series of them in the seat. I was very pleased when I found them in the center portion of the wheel. Each motor takes two wires, one pair is red/black and the other is blue/green. Each pair has a 2-conductor plug that plugs into the green PCB. These two sets of wires are wire-tied together near the PCB. I'm planning on cutting these wires, using them to power a small relay that will drive the series of other rumblers I hack from other controllers. In general, there is no need for you to go into the wheel unless you need to hack the buttons or replace the rumbler motors.
Fabricate a mounting plate.
The mounting plate needs to be made of thin metal, of a similar geometry as the area circled in the picture. The plate will be attached to the backside of the dashboard. I'll post pictures of the completed plate and dashboard interface when completed.
