It's a 4 banger. I'm at work at will let you know the number on the PCM. It seems right 37280 something something. I the doner motor was just sitting around at the shop I had it done at. I am no longer aloud to go there. But if I could this would be alot easier. Thank you all for helping.

P0B ECU is from a '96 non-VTEC Accord. VTEC won't operate with that ECU. To get VTEC to work you'll need a P0H ECU. This TSB lists ECUs for automatic '96 - '97 Accords:

Ignore that plug. It's for the VTEC pressure switch. The P0H ECU has no circuits to operate it. VTEC will work fine without it.
