Need help injector wiring under valve cover
 

I am working on a 2004.5 Cummins 5.9 24V Manual Trans
My neighbor was replacing his injectors in his truck he had removed them and took them and had them tested and installed new tips. On his way home from picking up the parts he had a massive heart attack, he is not doing well and his wife really needs the vehicle repaired as it is their I only transportation I figured out how to install injectors and cross tubes and valve adjustments the only thing I'm not sure of is the wiring under the valve cover for the injectors he removed them from the clips on the side of the cover and stuffed them in the middle of tube not sure what color starts on the first injector is is red and brown or yellow and orange and which side if injectors do wires go to and the sequence they go in. thank you in advance for your help I have been looking for hours can't find any pics with a complete break down
