Hey guys I'm in the middle of a swap to a 6 speed manual but I ran into an issue. When we disconnected the TCU the car started up fine. So we ripped out the auto and threw the 6 speed in but now the car isn't wanting to start or do anything at all. It just turns the wipers on and makes a buzzing sound

Mazda

Think I'll need to throw the standard harness in?


EDIT: pretty sure I know the issue and it's a grounding fault in the engine bay, gonna take break clean to the grounding areas and try again.

I don't know about your model specifically but most Mazda's require the clutch pedal to be depressed before the engine will crank. There is likely a switch impacted by the clutch pedal to control this. Did your swap take this into account?
