Im gonna help my friend swap his motor..
his gonna swap a d16z6 to a 89 crx dx..
He came up on some SI wiring harness...
what do i have to do to the wiring shock towers
and to the ecu...thank you

 

You're going to need to do the MPFI swap.

You will need connnectors off the Si harness, that's it. Injector clips, Injector resistor box and it's connector and plug if you plan to use OBD0 injectors, Dizzy connector, TPS will need to be extended, etc etc etc

Do a search for MPFI, a couple of the posts have 4 links to informative sites...

I see search is down, here's a link for fourthgenhatch to get you started:

Yup,you gotta do the dp to mpfi conversion

 

so from the engine bay its okay rite?
just connect it to shock towers and get a resistor box..?
and from ecu i add more wires?

 

Basically you use your DX harness to make a new one, the Si harness is not plug-n-play.

Since you really only need a few connectors, I think it wouldn't be worth chopping up a perfectly good Si harness.

Any parts yard should have what you need..

You have to de-pin a couple of the ecu connectors and swap some wires around, it's not that hard, it just takes time and patience.

 

so forget the si one and use
the tutorial with the dx one?
and get some extra wires with
pins on the end?

 

Here are some links for you, all dealing with the MPFI swap:
