I have a 97 Accord DX with a f22 non-VTEC and had someone give me a 99 f23 VTEC. How do I make this swap work with the wiring harness that came in my 97 f22 non-VTEC. Is there any after market plugs I can wire directly into my harness. I'm lost. Please help.
Thanks

 

whats up man, i'm doing the same swap n about a month n a half, ported n polished f23 vtech head on a f22a4 block, planning on using my original intake manifold, as i understand u need the vtech ecu ( manual or automatic depending on Your car) and run a ground for the vtech solenoid and the vtech solenoid power from the ecu, u should just be able to add in the wire on a blank spot on your harness. good luck

 

Man I really appreciate the info.
Thanks

 

you'll need to convert from the f22s 2 wire IAC valve to the 3 wire that the f23 uses. the ECU you choose to use will make a large difference in how you go about it. I'm assuming you'll use the f23 ecu so you'll at the least have to run a wire through the firewall for the IACV

you'll also have to get around the f23 ECU immobilizer is you are using it.

 

How do I get around the f23 ECU immobilizer. I heard something about getting a key from Honda to get around the immobilizer. What kind of key would I need.

 

Do it matter where I pin the 3rd wire for the IAC valve and the hot wire for the VTEC solenoid into the f23 VTEC ECU? The swap that I'm doing is a complete swap motor, ECU and transmission from a f22 non-VTEC motor and ECU with 5 speed to a f23 VTEC motor and ECU and 5 speed.

 

Not only you need the key, but you also need the transmitter which is located next to the key cylinder.

You could run a p28 or any chipped obd1 ecu.

 

i was planning on using the f22 intake manifold on the f23 cylinder head so i have minimal wiring changes, with a 94 ex 5speed ecu. that will work won't it?
