LT-4 problems, need some help please
 

first of all, i did all the harness my self but i found out that only had two injectors ground wires and four red injectors wires, so i thought that the way it goes, so i kept going had everything done, yesterday me and my friend started putting everything in. he saw the same thing the injectors how the goes, because hes LTX8 each injectors have it own ground, but he thought the same as me maibe thats how it goes on the LT-4. well we put everything in, started setting everything up, put the handset in and we find out that it said that is program for a 4 cilinder turbo :confused: , so both of us were cratching our heads is that right or not, because his LTX8 saids 13BT. so im trying to figure out if is how it goes or i got the wrong setup? need help please ill apreciate it. thanks
