RESISITOR ON GRND CIRCUIT

IM MAKING A CUSTOM HARNESS BUT I HAVE A PNP LINK ECU FOR MY M52 SWAPPED E30. SO IM TRYING TO FOLLOW THE FACTORY DIAGRAM THE BEST I CAN. THE FACTORY HARNESS HAS A SHIELED GROUND CIRCUIT THAT RUNS TO A RESISTOR AND FROM THE RESISTOR ONE WIRE GOES TO A SENSOR SPLICE AND THE OTHER GOES BACK TO THE ECU. WILL I NEED TO ADD A RESISTOR OR WILL THE LINK PNP OPERATE JUST FINE WITH OUT IT?

Uh, might be a good idea to give some more information on exactly which circuit it is, the diagram you're referring to, the ECU you're using, and whatever else you can think of to help those who have experience with these vehicles.

Oh, and please don't post all in capitals - it's regarded as "shouting", and many find it annoying and harder to read.
