Can anyone help here, ive got a AU series 1 vct engine that was an auto, and a 5 speed manual i want to put into my series 2 forte but dont have the wiring loom from the ecu to the engine.

Do i just need a series 2 loom that will just plug onto the series 1 motor from the ecu? and whats the difference between the auto and manual ie: what else do i need in regards to wiring ect? ( I already have a series 2 manual vct ecu).
