Can anyone give me an idea of how to do this? I am going to be installing a LS/VTEC somewhere down the road and I need to convert to the SI wiring so I will be able to use the conversion harness and ecu I will be running. I am under the impression that it's basically rewiring the harness so there are 4 injectors instead of 2. I am not sure if I am correct but any help would be appreciated. Thanks

 

You mihgt have better luck in hybrid section bro

 

as long as you stay the same obd you just need to do the mpfi upgrade. Not to hard. There are tons of sites that outline this and talked about tons of time on here too.

Excellent work, thanks!

I'm assuming I am looking at that diagram from the front, with the wires going out the back, away from me?

 

the wire's are going into the ecu, as if you where looking at the ecu and not the plug.

 

nice work man
very helpful

 

I am swapping in a B18a1 motor in my DX crx...Can this chart apply to someone with a 89 crx DX using a 89 CRX HF mpfi harness? Would i do the same re-wiring as the chart says even if i am using a hf harness and not the stock DX harness? someone help!

 

Hf harness and Si harness are identical. The Hf harness is what I used for the 4 injectors and mated them to my DX harness, Works great!

I didnt use this diagram though....i used the hybrid board one, that really ol school one....its all words, with no pix so this diagram helps out greatly! But go to the hybrid board and get some additional info. Get all the help you can find.
