F1 real pedals

[posimosh]

Just for posterity's sake, for anyone trying to do a similar sort of thing with frex pedals and a different brand wheel. I'd just like to point out that Dave's explanation of the functions of each component in the frex pedal system have allowed me to confidently replace the computer power source with a simple, compact plug that powers the transducer, the relay switch (the box that originally puzzled me and made me super cautious about frying the whole system), the "lock-up" led light, and, in the near future, a motor from an ooooollllllddddd 3.5" hard drive. The motor from the hard drive SHOULD work as a tactile Lock-up warning that vibrates whatever it is attached to (the brake pedal, rig, seat, or wheel) at a percentage of braking pressure which can be set via the transducer box which had a little digital display which shows a real time, numerical representation of the hydraulic brake pressure.
I will report back with more detailed info just as soon as I find the time to transplant the hdd motor to the pedals, and get all of the spliced wiring tidied up nicely so that those of you tempted by a hydraulic brake can easily DIY one or pick up a used frex set and do the same thing I did without buying the frex power supply and distributor. Stay tuned...
(Thanks again Dave!)

I know this is an old one but I'm trying to do this now and could do with a bit of help.

I've got all the stuff I need but not sure about a couple of bits of the wiring.
