95 b series single cam motor, hatchback, need signal to vtec if that makes sense
Expert:  MASTER TECH replied 4 years ago.

ok a B series motor is a duel over head cam motor the D series is a single.

so your upgrading from a none vtec to a vtec motor. yes ?

Customer: replied 4 years ago.
the motor is a D15B, so I'm assuming yes

also the # XXXXX ecu is APR0692
Expert:  MASTER TECH replied 4 years ago.

ok you will need to run 2 wires from the vtec switch and the pressure solenoid .

the blk/blu wire will run to the pcm connector c406 and put in terminal D6 and the single pressure solenoid wire will run to c404 pin A4
