ya i am tryin to wire vtec in my car an i called a honda dealer shiip an they told me that i can take out 3 wires that go into my ecu an use those pins but he wouldnt tell me which ones or which pins i would use for the vtec

 

I dont know how to do it but we will need more info before someone can answer your question.

1. What year make and model car
2. What computer

 

try this.... https://honda-tech.com/zerothread?id=1171263 its like the 3rd post down. and youmight need those codes if youi end up throwing one if something isnt hooked up properly. just do a search first bro. you'll find a lot i swear. at least look around. if you have any questions just catch me on PM or IM me at tcs64hxc. good luck.

 

oh and as for the pins..... go to your local pick and pull, and grab a ecu harness plug. make sure to cut with enough wire to solder to. that way you have a clean install. you can either take it apart like it says in the above link, or do it the easy way and tap it with a hammer (the old plug that is) take the 3 pins and solder to your wire running to the engine bay.

best of luck.
