Change over to Vtec

[mac]

Looking for wire diagram for 2.2 Vtec that I have installed in
a 93 prelude that formerly had a 2.3 DOHC. I do have the
proper ecm for the Vtec. Any tips would be appreciated

[crazykid]

contact me on ICQ... i did the swap not that long ago...

you have to run a few wires... from the ECU... ( h22 ecu ) that arent in the wiring harness on a SR.. one is vtec solenoid, and the other is vtec oil pressure... ill have to look up the pin numbers on the ecu for you.

my icq # is 142372437

and ill try and help you out... i had to sit and figure mine out took me a few days... but when i was done theres nothing like hitting vtec for the first time...

Hey Bill.. since you have done it yourself.. and your typing is back to normal.. :D maybe you can do a little write up on what was involved.. the trials and tribulations.. It would be very good for the FAQ section. :thumbup:

FYI to anyone thats watching this thread...

the vtec solenoid wire is :
A4 green/yellow on the harness

the vtec pressure switch is:
D6 blue on the harness


when counting on the harness... ( this took me days ot figure out )

count like this:

1 4 5 8 .... ect.. you get the idea...
2 3 6 7

i did all the figuring out on the harness only using the wiring diagrams in teh chiltons manual.. avalible at Canadian tire

good luck
