Alright guys this is my first post and I need some help with my vafc. I have a 93 lude with a swapped h22. I have my vafc all wired up with the exception of the vtm wire. What does it do and do i have one? I can't seem to find any info on it anywhere. If I do have one do I absolutely need to hook it up? Any info is apprecicated...thanks guys!

 

u cut the vtec pressur switch wire goint into the ecu, and connect the vtm wire to the ecu

 

Go to apexi.com and go under documentation, the go down to Vafc wiring diagram if you have any problem finding it let me know and i will get it and email it to you

 

Alright thanks guys Ill check it out

 

Hope that helps its for the original VAFC:

 

I do have the manual but I thought I read somewhere that jdm engines do not need the wire...anyone got any ideas? ...
