tried to find wiring diagram for P28 pin out, vtec
hello welcome to the site.
what wiring are you looking for ?
looking for wiring diagram for honda civic EPU P28, specificly vtec
ok please give me year on these and i can post the etm pin outs
the p28 is obd 1 correct ?
92-95 ECU (not ETM)
Yes obd 1 is correct
ok give me some time while i load the info. you just need the pin locations.
your putting a b series motor in correct ?
I'm not sure, my grandson is swapping motors, I'll try and call him and get back to you
Yes it is a 95 b series
sorry for not asking all this at once.
what harness are you using stock b series engine harness ?
you need knock and vtec .
95 b series single cam motor, hatchback, need signal to vtec if that makes sense
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 ?
the motor is a D15B, so I'm assuming yes
also the # XXXXX ecu is APR069240076.925925544
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
