Can't seem to locate the TDC or REFERENCE sensor for the w126 (86' 420sel). Not referring to the REFERENCE RESISTOR. This sensor is similar to the CPS Sensor but has a 3-prong Female connection at the wires end!

It's somewhere on the drivers side of the engine near the front but I cannot find......

Anyone know where???

the sensor is in front of the driver, back of the block, about 1 oclock or so in the trans bellhousing. if you unplug the 2 wire, coax wire that plugs into the ezl, you can follow it back. good luck, chuck.
