I am taking a F22A6 engine from a 92 Accord EX with an automatic and putting it in a 91 accord LX with a manual and a bad engine which is stamped as being a F22A6 on the block. I have both the engines out sitting next to each other when i noticed the new engine has a canister under the intake manifold which the bad engine doesn't have. The wireing harness from the old engine obviosly doesn't have the wire for the silonode on the IAB, but i need to use it I think since the tranny's are different as well as the connections. Do i just need to run a wire from IAB to pin a17 on the ECU and a power wire? What can I do to make this swap work?

 

Even in 1992, the LX doesn't have IAB. (regardless of auto/manual trans)
So... you could grab the ECU that matches the 92 EX engine.

 

Thanks for the info, but just to make things clear. I don't need to do anything to the auto ECU to make it work with manual.

 

Oh yeah, that's right. The auto ECU will be looking for something from an auto-trans computer which isn't there. I think there's a way to disable that but I don't know the details. I suspect it might set a CEL but no affect on engine control.
