Thanks for the shoutout
@DionR!
My front spindle/brakes consist of a stock F,M,J spindle with the brake surface turned off of a 11" rotor to create a hub. The rotor is a 13.75" rear rotor off an SRT challenger and it has a Gen 1 Viper Brembo caliper. While reading the ribs on the back of the hub seems like a super easy solution, mine weren't evenly spaced. I don't know how much that would have freaked out the MS3. Secondly, there's no way I could have fit the sensor in there since my rotors overhang the hub quite a bit. I'm reading off the back of the studs. While I don't have it up and running yet, I'm sure it will be fine. I've seen a youtube video of a guy having 1 pulse for speed input. While I'm sure it works, the resolution has to be pretty crappy.
Dion was correct in stating the bracket I made attaches to the dust shield bolt holes in the spindle. I could have easily used a ball joint bolt hole if those weren't there.
You are lucky to have a trans speed signal. I have one of the older TKO500s and it doesn't have the provisions for an electronic speed sensor. Of course I could put one in the speedometer location, but I have a speedometer and want to keep it. I'll be making a bracket to mount the same sensor on the back wheel studs also. I've been waiting on Deutsch connectors to come in so I can get it all done in a day.
I also recently purchased an accelerometer for assistance in tuning the traction control. I also think it will be fun to make some autocross videos with overlay showing this data. If you don't want to spend $300 on a Holley or Fuel Tech accelerometer and don't have a problem "engineering' some things, Digikey has an accelerometer for $16. It's just a tiny circuit board (3/4" x 3/4"). You will need to come up with a little box and a way to mount it firmly in the car.
