Help Please - Crx Obd-0 To D15B Vtec Obd2A

Hello Honda owners.....my name is David, I'm from Chile, south america....
I have a question, and I think here is the place where you can help me....I have a 85 CRX Si, which came with a EW3 MPFI engine OBD-0- and I'm changing the engine for D15B VTEC OBD2a. I have all the engine harness OBD2a with the ecu. and I have the whole interior harness OBD-0

I want to match the engine harness OBD2a with interior harness OBD-0 .... and so have completely operating the cluster, and the other things to the engine to run properly


someone who knows how to do it..to know what wires i have to look...thanks

This is going to be a very difficult conversion. You must run the obd2a ecu in order to hit the 3-stage vtec. you're probably one of the first to really attempt this that I know of.
Good luck! and if you can document what you do, you'll be an internet hero!

I drew on paint to see if you understand what I need to do
I need to match both harness, but I need to know that wires will use and which are not

help

I would like someone expert told me, if I'm right or wrong

somebody.... this is honda swap!!!

i think definitely it's the most difficult swap question of the forum in many years....
