Aug 2009:
FIdle output is now green, Spark A is now Orange rather than Yellow or grey
April 2009:
Injection Bank 2 cable is now purple rather than green.
February 2009:
Spark A output is now Grey rather than Yellow.

These are specifically drawn for the configuration that I sell the MS1 and MS2 ECU's and wiring harness.
