92 f22 to f20b swap. harness?

[Mrdanbkidd]

Looking to swap my wagon but before I start tearing apart I haven't been able to get time to go searching for info. I know the f20 will drop right in. But my question is besides ecu trans and motor what do I do about a harness? Where do you guys find to be a great place to go to get harnesses for your swaps? And if there is other things involved besides a drop in and harness please let me know!!!

For the F20B there is no OBD1 ECU that will plug into your stock harness to run the car. You're stuck with getting a chipped and tuned ECU to run this swap.

Unless that ECU is a P72, you've added IAB functionality to the ECU or you've swapped to a Skunk2/Euro R manifold then you'll have no way of operating the IAB butterflies in the F20B intake manifold. That will need to be addressed.

The mounts are the same with the lone exception of the mount bracket that bolts to the timing side of the engine block. That will need to come from a '92-'96 Prelude with an H22A1/H23A1.

The VTEC solenoid on the F20B is a one wire hook-up because it is a JDM engine and that VTEC solenoid doesn't use a pressure switch. A US VTEC ECU will look for that switch and if it is not present it will throw a CEL and not engage VTEC. You can either swap it for a USDM H22A1/4 VTEC solenoid(B16A/B18C works also) or you can remove the threaded plug and add the necessary switch to it. The switch can be had from any VTEC solenoid in the junkyard, including the extremely common F22B1.

The distributor will need to be modified using internal parts from your Accord distributor or have an OBD1 USDM DOHC distributor purchased. This is external coil like your car and will plug into your harness.

The injectors can be used by cutting off the plug at the injector resistor, combining all those wires into a common join and soldering them. To do this you'll still need the OBD2 pigtails for the injectors. If you don't feel like doing that then you'll need OBD1 H22A injectors which will plug right in.

The wire harness you'll need is the one that comes off of your F22A. Just adapt the wire for the VTEC solenoid, the VTEC oil pressure switch and the IAB wire into the harness and you'll be fine. There are actually sellers on eBay that make subharnesses specifically for this purpose.

If you need clarification on any of this then the information is all over this site. Please search in the future and don't excuse yourself for not having time.
