fuel injector help

[klaasjoe]

I am gonna install some sard injectors on my 1jz but I dont know if the wires have to go to a specific side of the injectors. All the wires on the harness are different colors. If anybody knows some help would be awesome
thanx

I think they need to because if you switched them it would reverse there polarity. Making there cycles backward.(alla power window) some please correct if I'm wrong

 

[klaasjoe]

how do I tell which wire goes where on the injector since there are no markings

Polarity is irrelevant....

Well, if the hairdryer were DC it would
