will a 06 wrx wire harness from a an Autotragic equiped wrx work in an aplication for a manual transmission equiped car? Does it simply have additional equiptment for the auto-tranny control? or is it entirly unuseable for my build where I plane on using a manual tranny?
Doubt it. You have the ecu to tcu connections, then the dash cluster is different, so you have those wires that are different. You would be missing the clutch wiring... Russ
