Are the pink wires all grounds,and the multicolored wires the + wires? what would it affect if i had the wrong plug on the wrong injector?. I'm still tryin to figure out why my truck is missing at least 50 hp. Can the friggin tune be off that bad?

 

tune and injectors lol

its been over a year...i went with the same color being the ground and the different color being the hot lead

 

Pinks are all +VE. PCM turns the injectors on by grounding the other wires.

 

i just matched the pink wire where the stock truck ones went to on the injector.
