Hmm all hooked up hunh? There is also a knock sensor at the back of the block that must be hooked up otherwise vtec will not activate. Looking at the engine it is on the far left side under the intake manifold. I believe it is a green plug.
There are 2 wires.
Wire the black one to the chasis ground and the other one to pin B19.

After that your all ready to go. And yes, you will notice a difference when vtec is activated. You will be able to feel it.

Do you have the second o2 sensor hooked up also?>

i havent gone outside yet to check the knock sensor but when i was putting on the catback exhaust i noticed a 2nd o2 sensor but the wires are cut and not connected to anything what do i need to do about that? thanks alot i really do appreciate your help.

the 2 o2 sensors should be right by the exhaust manifold, by the engine code stamp!!!

For the o2 sensor you have 2 options.
1.Splice them both together and run them to the stock single o2 sensor on your wiring harness
2. (Best way) Run the second o2 sensor to pin C8

You will need to hook up the knock sensor also. If you need i can take another pic for you.

thanks for all the help i just went to the junk yard today and found a del sol that was wrecked and saw the wires that where suppost to go on to the vtec so now i have the wires but on the o2 sensor.... my car has a after market header on it and there is no o2 sensor on it... what should i do there is a o2 sensor down further right before the cat but the wires are cut and just hanging there... thanks again tyrell

There has to be an o2 sensor.. Try looking behind the engine where it meets up with the CAT converter.

Wait Wait, you mean that in a junkyard by you there is a del sol Dohc vtec with the engine still in it? OMG!!!!!!!!!!!!!!!!!!! grab the engine asap!!!!

[elaxxx]

ill take sum pics tomorrow of my exhaust so you can see what i am talking about... and about the del sol yah its a dohc vtec but it has been gone threw... such a shame... parts off the engine, they should of just sold the whole engine, but i got what i needed off of it so i am happy... lol. talk to ya tomorrow Tyrell
