BLUF: Car is a 1987S4 US spec auto. Do pins 2 and 3 on the CPS (car side) both go to ground? Pin 2 is Brown and Pin 3 is the EMI (or some other shielding) shielding. See below for the rest of story. Thank you.

Need some help please with the crank position sensor (CPS) wiring (car harness side). I recently replaced my CPS while taking shortcuts; basically only removed the airfilter assy and MAF. I was able to get the CPS out after about an hour of screaming, but damaged the wiring to the connector (car side). I diked the connector and spliced in new wiring, but did not check ohms readings before doing so. On the Schematic (assuming RPM-Sensor=CPS), it shows pin 2 (brown) going to EZK CU 6 and pin 3 (shield) going to EZK CU 24. Mine both go to chassis gnd. Is this correct-I wish I had checked the splice point values prior to heat shrinking the hell out of them.

On a side note pin 1 (white) does not shoot to gnd.

Thank you for the assistance.

Well, went for broke and hooked it up-car starts and runs fine (drove for about 10 mins). I assume that if they were both not supposed to be gnd that it would not start (or run properly).

I replaced the CPS connector harness side with no issues but I used a connector off of a used harness so cut the wires a few inches back from old and new connectors then spliced, soldered and heat shrunk each wire.....no problems.

Mine is hard wired due to wearing out of the stock harness and connector. If your car runs, you were close enough!!

I was just worried that I had got a few strands of the shield soldered to the brown wire on accident. I was very unwilling to cut all of the heatstrink (I went overboard). Did you ohm check at your completion?
