I'm swapping a B16a1 in my 91 dx hatch. The motor came with the SI harness for the injectors. I know the Green one plugs into a resistor box:



If I plug the white one into the harness on the car in this picture:



The DX harness on my car doesn't include the additional injector wires that the SI harness on the motor does right? So If I just plug that in, its not going to work. Is it easier just to modify my DX harness with the correct injector plugs and add the wires for the 2 new injectors or to somehow use the SI harness on the motor?

 

It's easier to modify the DX harness. I've been through it. I did it a while back for my ZC, then a friends ZC and now another friend with a b16a.

 

Making the Si wire harness work is a big pain in the ding dong, but not impossible.

 

Use the dx harness, if you would have searched for 5 seconds you would have found your answer.

 

Si engine harness is gonna be 10x more difficult to adapt to your dx. just do the dx-mpfi conversion that the majority of people do using all the plugs that u got on the si harness accordingly.

 

on the b16, unravel the electric tape and plastic sheathing. Just use the green plug and all the wires that run to the injector plugs. hth

 

Thank you, that does help!
