Alright, I'm not asking how to swap, there's a lot of right ups for that, what I need to know is what do I need to do to the wiring harness? I got the ecu and dizzy jumpers for obd0 to obd1 but will the d series to b series have a different pin out? (will my injector eires be plugged up to my horn?) Lol, I know to wire in vtec and the sensors I dont got on the ef, but will all my current plugs be the same?

 

Yes plug and play most of them

 

Great to know, thanks.

 

Injector plugs may need to be swapped out depending on if you use obd 0 or obd 1 injectors. If you use obd 1 injectors you have to delete the resistor box also.

 

you sure thats for obd1 and not obd2?

on my 99 gsr (obd2a) when i put OBD1 injectors in for boost i had and current am running a resistor box?

can you shed some light on why obd1 injectors dont need a resistor box?

 

hmm didn't know you could do that. cool

 

I'm running an obd1 b18c, and am not using the resister box for the injectors. I always thought you didn't use it for obd1 and obd2 cars.

 

same here

 

The obd1 jumper harness lets you delete the resistor box but would still need to wrap the wires that come to the resistor box or else won't run.

 

What exactly do you mean by wrap the wires that go to the resistor box?? Cut the ones that go from the resistor box to the injectors?

 

I've been told to pull the box if u run obd1 or 2 inj but ppl advise to run obd0 injectors if you plan on boosting because most aftermarket injectors will require the box.

 

Your car won't start if it is just unplugged.

 

You unplug the box. Cut the plug and twist and solder the black/red wires together if your running obd 1 or 2 injectors.

 

91 EF DX is correct i did this when i ran obd1 for tune purpose abd the bay is much cleaner with out a box...

 

Ok well wich obd SHOULD you run? For future boost

 

I'd definitely want OBD1. Then you can use an ecu that works with a hondata and you'll be able tune your car properly.
