need help oil pressure switch bypass!

[KoloJak11]

Ok so I have a 1994 prelude Si. Had h23a1. I just put in a h22a4 and got a chipped p13 off ebay and I Wana wire my vtec. Only problem is my solenoid doesn't have a vtec oil pressure switch for some reason. I was told you can bypass this by putting D6 to A4 but will this make my vtec engage? Or do I still need to hook up the green w/ yellow stripe wire on solenoid to something?

Forgot to mention that I am using h23 intake, fuel rail, injectors, and throttlebody! So I can use obd1 ecu

 

[KoloJak11]

Comon guys I know someone has done this? Anyone got a reliable link on how to do this?

 

[josh_crewdson@y]

easy fix would be a jdm ecu.. i dont know off the top of my head how to bypass the pressure switch..

 

[KoloJak11]

How do I tell if I have a USDM or JDM p13? Cuz I got mine on ebay chipped 5k vtec/10k redline

 

[KoloJak11]

Ok just took apart my ecu and it is intact JDM! How do I hookup vtec?

i have a pinout digram if you want it for the p13 easy to read too if the colors are on the plugins just run a wire

Please and thanks!

Just my luck, no computer and droid 2 wont let me download that file lol

 

[splashofpaint]

then i guess you'll have to find a puter.....lol

 

[KoloJak11]

True true lol, does A4 and D6 go together and to the green and yellow wire on solenoid?

Your amazing!

 

[KoloJak11]

Ok so if my solenoid doesn't have a vtec pressure switch and I have JDM p13 ecu what would u do?

 

[splashofpaint]

is this what yours looks like with out the switch just the solenoid //////if so then buy a switch and put it in
