Hey hope everyone doing good. I did a few searches for this and maybe I'm not searching the right terms but I'm looking for a little help in rewiring the harness.

I got a 96 Civic Coupe EX and looking to drop in an F22A1 engine from an Accord but have the majority of the F-series harness and the full EK harness so I'm looking to marry them so I can drop the engine in.

Any help or directions is much appreciated!
Thx

You are on the right track !!! Start with the stock Civic engine harness, lay it over the F22A1 engine, plug in what works, change all plugs that need to be converted, lengthen or shorten all necessary plugs in order to reach the same sensors on the F22 engine, set the engine into the bay and then plug the engine harness into the car.

In short, you will lengthen the alternator wiring, lengthen and change the IAT plug, change the distributor plug (if your engine is '96+, you will have to bring the wiring of the two sensors located at the crank around to the distributor), and swap the Civic EX fuel injectors into the F22 fuel rail. This list is not all inclusive necessarily... but it is a good start.
