I need a sanity check on this, I think I already know the answer.

Getting ready to do my mpfi swap and I am planning on using obd2 injectors out of a d16y8. So in order to do this, I know I dont need the resistor box.

My question is, I know where all 4 signal wires are coming from, but does it matter where the ground wires are coming from? I ask this because on the DX I only have two of the ground wires coming from the stock injectors. Can I just splice into them to make up the additional two wires?

 

I believe as long as the injectors are grounded it will be fine. A ground is ground.

 

Thats what I thought. Thanks.

 

do you mean the black yellow wires? if so just solder them together with four other wires and then run the four other wires to the red blacks or whatever it is on the injector. thats how i did it on mine.

 

You need to give them 12volts+, not ground. Are you clear on the dpfi->mpfi>obd1 swap?
If not, try my site.
