Default SWAP: VX engine Swap in 95 EX/SI, EX/SI (sohc vtec)eng in VX

I have two cars, a 92 VX-hatch and a 95 EX 4-door. I want to swap the engines in these cars.. In other words, I want to put the VX engine in the EX car/body/wiring. and the EX D16z engine in the VX body/wiring.
I've been told that putting the EX (D16z) engine in the VX body/main wiring harness is a straight plug and play application. (the EX eng harness plugs into the VX main harness with no problems or additional wiring is needed) and use the p-28 ecu


Pluging the VX wiring into the EX main wiring harness is a different story. I know the VX runs a 5 wire o2 sensor whereas the EX is wired for a 4-wire o2 sensor. Does that mean I need to run a 5th o2 wire to the ecu by pinning it ? Are there anymore additional wires (or hardware) that need to be wired to the P-07 ecu?

If you're wondering, I'm using the VX (D16Z eng) car in Honda Challenge (H4) as a Civic SI, and my EX 4-door with the VX engine will be my daily driver-trying to get the VX gas mileage in an EX

anyone with firsthand experience?
thx
