I have acquired a 1995 ex w/h22 swap. I have the two below CEL's.

14-IAC Valve (Idle Air Control)
defective circuit or unplugged / defective sensor

22*- Accord Civic CRV CRX Del Sol Odyssey Prelude
VTEC Oil Pressure Switch
defective circuit or unplugged / defective oil pressure switch

I have the p13 ecu, what do I have to rewire/plugin or ground and reroute to make this car run like it should? Right now I have no VTEC and uneven idle if driven or if the AC is turned on.
