Engine swap wiring harness question
Is the wiring harness the same in the civic hx as it is in the ex as far a vtec wiring goes and what not? My question is because if i was to swap a B18C1 into my 96 civic hx would i be able to use the stock wiring harness?

The hx is not wired for vtec, but the ex harness is. You could use the same wiring harness, however you would need to wire up vtec yourself.

I'm not familiar with HX nor with EKs too much. You will need ecu from the same year era (as I like to call it 96-98 or 99-00), I'm pretty sure vtec is wired up if not it's an easy fix. I also believe you will need to rewire the O2 since hx uses 5 wire intead of 4 wire O2. Maybe extend a couple of wires. I would suggest using your stock wiring harness.
if the ecu not your generation. You can get an adapter harness and just run a chipped p28 or some. It still nothing that you shouldn't handle if you can put the motor in by yourself.

use stock wiring harness, add knock sensor wire, iab wire, re-wire from 5-wire 02 to 4-wire 02. use a 96-98 gsr p72 ecu or use an obd2a-> obd1 jumper harness to run a 94-95 p72 ecu (can be chipped later on)

oh yes I forgot about that (first though it was type R lol so forgot about the IABs), and forgot about KS.

You need to wire up the Knock sensor, IAB, 4 wire o2 conversion.
Or you can run a Chipped p28 with a OBDII-OBDI jumper and you would only need to do a 4 wire conversion. You need a Skunk2, Blox, AEB's intake manifold to do this since there is no IAB
