I have a 92 honda prelude si non vtec and i swap with a 2.2 blue top dohc h22a vtec engine.
my car runs well with the p14 ecu that was original ecu there but the vtec wont work.
I was told to get a vtec computer from the prelude vtec which is the p13 ecu 0bd1

When i plug it up the vtec still wont come in

I was told i have to do some extra wiring to the vtec solenoid,knock sensor etc

Question: What type of electrical wire should i buy or where can i get the right wires to wire the vtec ?

This is the instuction i was giving on how to wire it

 

I would guess 12 or 14 gauge wire

i couldn't get anywhere on this site because it's blocked here. that's the site in the FAQ section on here...good luck

 

thanks bro
Im actually a rookie to anything that has to do with electrical

Do you think it would make a difference if i get a automatic P13 or manual P13 for a 5 speed manual transmission.

Would there be a difference in the way it runs?

 

whichever is cheaper...there is a writeup someone on how to convert one to the other. i'll look through the FAQs...you should for issues, too.

 

well, it was for a 5th gen...

maybe you can find something in there to help you. you may have to look around for a p13 writeup, if there is one.

 

Stick with the manual p13...

 

well i dont have a manual p13 i got this i got an auto for 60 bucks so i took the offer seen that they usually cost 250

I have another issue my selenoid dont have an oil pressure switch to connect to

Do you think i need an oil pressure switch for the selenoid?
