About the AF sensor wiring..
The sensor itself is easy enough to wire, just plug the K20 C101 wire to the sensor.
The second one have to be wire in the E connector if my memory is correct. You must had 2 wire in it (refer to the manual shop).
The major problems is about hte Sensor heater relay, I still get a code about it, so I can't help you and I'm tired to work on this detail, so I'll take time again this summer and when I'll find how to wire it correctly I'll make a second sheet for the sensor.
But...in fact..
AF sensor : Signal + and signal - MUST be correctly wire for start the engine
Secondary 02 sensor : Only here for advise you if your cat converter work correctly(something like useless), but will sort a code if it not wire.
Heater Relay : the sensor heater is only here for heat the sensor when is cold. o2 sensor give better result when is hot, so for a better fuel effiency (when engine is cold only)is great to have this one correctly wire. But like the last one, if is not wire correctly, a code will be on (41 exactely)
The pin 7 Fan control wire is also the wire you must connect on the thermoswitch.
This one is the switch start you fan when the temp come to hot. Take the Civic one (connect on the thermostat hosing on the block) if the RSX wasn't in the radiator (or if you do like me, put a custom one with a fitting in a pipe for the switch) Connect one wire to the ground, and the other one on the FanControl wire.
About the FanC wire, I take it neer the fusebox connector (and it work), but you can take it a the C101 connector
Other Think I realize and highligted in another tread by xproductionz
you dont need the rsx throttle cable if you wanna save some cash... you can use any 92-95 civic sohc throttle cable... thats what i am using now
you dont need the fuel line, brake booster line, and purge line cause the original ones from the motor will do just fine...
you dont need the 90 accord negative battery cable.. pointless
your original shifter assembly will work with the swap so dont buy it like i did.. waste of money once again.... just buy the cables
and you dont need a custom hood latch from hasport
RSX (k20a3 model) axles gonna work too
You can use your Civic clutch master cylinder but you gonna have to make a custom line and use your Civic rubber line. The RSX line don't plug on it...
About the distribution belt... I have a 2001 dx civic without AC... The size I needed for my distribution belt is 53 1/2 inch ... Dayco have a good one in this size (7 groove)
Its highly recommended to use a RSX fuel pump because the Civic one only give the minimum a k20a2 need
