I just put a 98 ex motor in my 95 dx and I used my dx engine harness for the swap. Where do i wire the Green/yellow wire for VTEC spool solenoid, and the lower Blue/black for the pressure switch if there are no slots for them?

 

bump

 

with a stock dx harness and ecu (if ur using the dx ecu) theres no where to wire it. you need to get an aftermarket vtec controller. which is 5 wires for the vtec control. vtec solenoid, oil pressure switch, tach signal, power and ground. something like a VAFC will obviously have a few more wired. i have an old vtec controller layin aroiund that ive been tryin to sell. its not very flashy lookin but it works.

 

use an ex/si ecu for a 95 obd1 p28 should work fine. as for wiring, just wire the vts and vtm directly to the ecu. and ground to any ground. those 3 wires and p28 ecu should work fine if your on a budget. or you can do a super poor way and buy an rpm switch which i really wouldnt reccomend.

 

that would work. idk how hard a P28 is to get a hold of or how much they are cause i have a 95 ex so it has a P28.
