Hi
Im trying to figure out what goes where on my wiring and so far im stuck with the following questions:
The engine has a pectel t6 ecu with wiring that is off a other car than the one its currently fitted to.

1: Tacho output, is this a pin i have to configure under ECU hardware setup => multi function output channels? i would believe that this was a static pin, but looks to me that it has to be configured in software to one of the 6pwm channels?
Which is strange, as none of the pwm channels is connfigured with tacho_Drive and i would assume that the previous owner had a tachometer?

2. 5v sensor supply (ecu pin 22) this is a output pin right?
so if i power on the ecu i will see 5volts all the time here?

3. On my ecu pin 21 is configured as water_injection.
Will i see 12volts on this pin when waterinjection tresholds are met?
In other words is it this pin i should connect to my water injection pump relay?

4. On the coilpack i have 3pins
Left = ?
midle = ground
Right = 12volt
I assume that the left pin gets signals from the ecu to trigger a spark?

More questions will probably appear as i start connecting this
