Petrol injector negative and positive?

a11mcr · Oct 25th, 2019, 22:25

Hi all I'm trying to find a diagram of the injectors on my 2005 t5.
I have 5 green wires and 5 coloured ones but need to know which ones are positive and negative.
I presume the green are negative but not sure

what are you trying to do, the positive is the thick wire iirc

looks like green power, black ground, colour is the signal to fire

No sign of earth wires from the Volvo diagram, hence my error
