Hi,
I finally finished wiring my car for MPFI in the engine bay.
I just wanna explain how I did it to make sure i did it correctly.
I took all the left side injectors and ran them to the power on the injector resistor box. The other wires on the right side of the injectors the striped ones I ran to the other 4 wires on the injector box.
Then I just tapped into the distributor wiring harness and put C1 and C2 wires from the ECU into the two wires as described on the distributor harness.
Does it sound like I did it correct for the engine bay?
Thanks

I think you did it wrong. To me it sounds like all your left side wires come together at once 12+ source. And all your right go to the 4 same colored wires on the box. The right side is ok, but that left side was supposed to be hook to each of your injector signals. Your car isn't going to run like it is.

Ok,
I took all the odd colored wires and soldered them together then ran it to the 12 volt red wire on the injector box.
The A3 and A7 wires I wired into the injectors and the 2 DX injectors I took to solid yellow and red wires to the #1 and #3 injectors on the left side.
The striped wires on the injectors i wired to the 4 black wires on the injector box.
However, I still have not wired in the opposite wire from the 2 DX injectors, where would they go?
Also what do you mean by left side and right side?
The striped wires would be right and solid odd color wires left?
Thanks

I really have no idea what your saying.
Go read my How-To and it will tell you exactly in detail how to do this wiring.

yea sorry about confusing you.
I finally understood how to do this injector thing and just finsihed the wiring tonight.
Now all I need to do is get my axles in.
Then Ill start it up and see how it goes.
Thanks again for your help.
