Some Injector Help, Please!

OKAY, so correct me if i am wrong, so the REAR SEC. wire colors are LT GRN-RED(hot wire) and BRN-YEL(ground), REAR PRI. is LT GRN-BLK(hot) and BRN-RED(ground), FRONT SEC. wires are LT GRN-WHT(hot) and BRN-WHT(ground), FRONT PRI. wires are LT GRN(hot) and BROWN(ground). I realize that since i am bypassing the injector resistor box that ground for the injectors will be BLK-YEL basically. So the only question i have is.......when the scamatic/wire diagram says FRONT SEC./PRI. is that refering to the front rotor chamber (T1,L1) and REAR SEC./PRI. refers to the rear rotor chamber (T2,L2)? Please and thank you.

hmmm... so you know they dont like bumps around here they might cut your toes off. Anyway i think your talking about a s4 t2 cause these seem like the wires mine have the t1 l1 is for ignition but the 1 means front rotor so in the wire diagram r.secondary is secondary injector rear rotor. the rear rotor being the one closer to the firewall. The black yellow is the power. As you can see from the diagram all the injectors have the black yellow wire.although This may look like a ground because it is lower in the diagram its actually power.but being that fuel injectors are normal ground controlled by the ECU(ECU grounds the circuit when it wants to fire the injector). The LG/R for the rear second is actually the ground and so forth for all the other. i dont know where you got this bro yellow wire from. or brown red. maybe you dont have a t2 but the power is gonna be the same for all the injectors. Are you going to high impedence injectors? is this why your bypassing the resistor box? the resistor box is on the power side im almost positive thats how i have mine wired up. The one power feed comes in and all the resistors parrell off in there own branches and feed the injectors. Hope this helps...
