Default MPFI intake question

I have a D15B2 DPFI setup, 89 DX.

I was told you could use a D15B7 intake for the MPFI swap so I bought one since the price was right. After the fact, i realized that these were from OBD1 set ups. If I have OBD1 injectors, do I just keep them in my OBD0 setup (PM6) just with no resistor box?

Also, being from an OBD1 system, will I have any sort of connecters on the intake that my obd0 DPFI won't have?

Thanks

Are you converting to obd1? If not you cannot use the injectors. You will need the obd0 injectors with the resistor box.

The manifold will work fine though.

Forgot to add, all the plugs you need are already on your harness with the exception of the injectors and resistor box plug. You'll need to probably lengthen the TPS, IAT,and EACV wires. I usually lengthen those 3 to give me enough room to move them around when removing the oil filter.

Injectors are independent of OBD configuration. The conversion process to run those injectors is covered in the FAQ. As for that manifold you can use it but you'll need a throttle body that matches the flange if it didn't come with the original one.

^^ this!
Just reiterating to make it clear that you can use either style injector.
There is no such thing as an OBD0, OBD1, or OBD2 injector.
If the flow rate is correct, you can use it.
They are either 'peak and hold' type or 'saturated' type - one is 'low impedance' and requires a resistor box.

Pretty sure mine are high impedance. Thanks for the help guys, and thanks for bearing with my constant questions. I'm gonna hit up a local junkyard tomorrow and find me some injector plugs and distributor.

Sorry for my constant questions. I found some injector plugs at a junk yard off an Accord. I modified my clips to fit (I've confirmed my injectors are high impedance.)

I seem to be getting some conflicting info, all wire colours aside, which injector is #1? Towards the distributor, or opposite?

#1 cylinder will always be closest to the timing belt regardless of engine.
