Hi guys, I need a pic or just the locations of which fuel injector goes to which cylinder on a MPFI engine. The SFI routing was a no-brainer, but I can't tell by the MPFI harness I got. I have never taken apart a MPFI engine to know.
This is what i have to work with:
Thanks!

There are only 2 injector circuits. The 3 far ones go towards the front of the car, the other three toward the back.

Ok, I saw there were only two set of colored wires... (blue/pink & green/pink-blk). According to their placement and your help, I'm guessing the blue are towards the radiator and green are towards the firewall.
Thanks Cliff.

The 3.1 MPFI bank fires the injectors. There are two banks, the front three and the rear three. As long as you have three injectors on the right bank, it doesn't matter what connector goes where. When you connect the harness, and route the wires, the length of the wires is just enough to get to each injector. I had the same thing happen to me a buick with a 3.1.
