Default Please help me out guys with my swap!

Hey guys I am in the process of swapping my old usdm d15b with a jdm d15b.

I have the old motor out of the car, and have swapped the wiring harness over to the new jdm d15b motor.

I bought a manual P28 ecu.

I need to figure out how to wire up the vtec solenoid, and i read somewhere that I have to re-pin the dizzy? is this true, all my stock stuff is obd1 so lmk what you guys can help me out with

i found the wiring diagram on the honda-tech site on how to wire the vtec, but i dont thing its for my setup?? i dunno just help me guys ASAP please thanks!

Alright what you need is a P28 pin out diagram for the ecu .....you need to only wire in the two plugs for vtec and ground the black wire to the valve cover or the solinoid itself....you dont need to rewire the dizzy and if you have a 1992 civic vtec is pre wired into the wire loom after that only ex/si models which came with the vtec motor came pre wired for it....

its a mini me but same thing
