93 Non vtec into vtec

[AUT0]

I just put a 1.5 liter vtec out of a 92-95 VX into my 93 civic DX.
What do I need to make this work?
I have the ECU from a VX and the Engine harness from a 95 civic EX Auto trans.
Will that harness work?
What else am I missing?

you will need to wire up VTEC from the ECU to the cannon plugs on the shock towers
and the O2 sensor is different (5 wire)

might be some other stuff

More help please

Does the cabin harness need to be for a 1.5 vtec or will a 1.6 vtec work?
Also the engine harness I have is out of a 1.6 auto and my car is a 5 speed.
Is that a problem?
