does anyone know which pin number in the ecu runs the vtec ...i wired the v-tec but don't know which pin to connect it to. i have a 95 prelude and i swap the engine from h23 to jdm h22a1 please let me know thank you.

A4 = Vtec Solenoid
D6 = Vtec Oil Pressure Switch

There are 2 wire tha come out of the vtec pressure switch, one is hot and goes to pin D6 and the other can just be grounded off on the motor or on the chassis

which one is A4 and D6

 

if you take the ecu and look at the pins as if it were in the car, say you lay it on a table with the top facing up and you look as the pins, the "A" pin numbers will start on the very right, Example:
Top side w/ the sticker
----------------D6------------------------------------A4---
l --------------\/---- -------------- -------------------\/-- l
l l oo . . . . . . . . o ll . . . . . . . . ll oo . . . . . . . . ooo l l
l l oo . . . . . . . . o ll . . . . . . . . ll oo . . . . . . . . ooo l l
l -------------------- -------------- ----------------------- l
-------------------------------------------------------------

hope that turns out right...change your post title to make that search friendly...like ecu pins diagram for vtec.

 

i'm still getting a check engine lights if i put my new ecu in.... why is that? right now i'm using my stock ecu for h23 so that i can use the car. i know it will not open the v-tec but i don't get an engine check light. does anyone knows?

 

on the v-tec oil pressure there r 2 wires does it matter which one goes to the ecu and which one goes ground? if so let me know which one is which?
