Default F23A1 swap into CB7

In need of some harness help.
Swapping an F23A1 into my CB7, as well as going from AT to MT. My CB7 was Non-VTEC. I have all the interior parts, clutch master and all that stuff.
I've found all sorts of diagrams for civics and integras showing what pins to relocate in the harnesses. Need help with an accord diy diagram.
Also (this is my first swap) will I need any specific ECU with VTEC, or is it trans specific also? What I mean is can I use an ecu from an auto, or will that screw it up?

Check out the Accord FAQ at the top of the page, look at the F22B1 engine/head swaps into CBs. Basically the same as I take it you will be using a 94-95 B1 ECU.

You need to use the F22B1 ECU from a 94-95 EX Accord for easy startup.
96/97 is OBDII and 98-02 A1/A4 PCMs are just gonna be a PITA for non emissions swaps. Other option is Integra/Civic ECUs but those will require a tune to have the car properly operate.
You can 'convert' an AT ECU to MT by removing a resistor IIRC, Google will net you the results you need.
