Under the new 85 4runner today dumping all the fluids (looked good) and saw a bracket with some wiring and a sensor that must read a magnet on the driveline. What's this for? Hopefully not a mercury switch or something my ex wife is installing along with some C4!!

Obviously it isn't a speedo sensor as there is a speedo cable going into the t case. Its at the slip end of the driveline near the transfer case.
