so this is what i was wondering. of course i have an auto in my 03 but i dont have the harness for the 5 speed speed sensor. so if i took the ecu and harness from the 00 sonata that im pulling the tranny from would it all plug and play with my 2.4 sohc? and if it will that should correct the cel and reverse light and starter switch wiring issue......
