Ok so when rewireing my car I found a sensor in my 91talon tsi it's a gray box with part number MB863749 witch comes up as Cruse control module and my harness from a 90 laser doesn't have the same plug. Now my 90 eclipse gsx has a gold box MB649318 speed control unit. And this plug matches my harness what's the difference and from what I have seen the gray one MB863749 is needed for 2step I will be using aem pro ems ver1 so is it needed for 2step?
