I'm installing new fuel injectors and electrical fittings for my fuel injectors. The new fittings came with a pig tails with one black wire and one red wire. The old electric fittings have a yellow stripe wire and one Green, black and white wire. Which one is going to be the hot and which one's going to be the cold? If Any one knows it would be greatly appreciated.

 

According to the wiring diagram..... all of the power feeds are the same color, Dark Green, with an orange trace, the 'other' wires are the control circuits. Since the PCM is just energizing solenoids to fire injectors, I am not sure that it really matters which way they go onto the injectors, just so long as the control side wire goes to the CORRECT injector. Have a look at how the current connectors go onto the injectors, and set the new connectors up to keep the same polarity? Should work.

 

Hey you I knew you would come through for me. Thanks for the information. It's going to take me forever but that is exactly what I'm going to do. I'm going to replace one of them at a time. That way I will not get anything mixed up. And of course today it is Africa hot in Georgia!!!!!!!!!!
