JDM H22A 4th generation manufactured February 1993 so it might be considered a 1994. Need to wire the motor to the ECM but don't have the motor pinout. PLEASE HELP!!!!!

Got one. Truth is I'm color blind so naturally electronics isn't my specialty. The motor pin out is all I need to complete the install.
