alright here's the situation

B16A1
90' crx si
obd0 PR3


i know where to wire the vtec to my ECU, but where do they go on the engine?

1)where do i wire the vtec pressure switch? is it that green plug under the vtec seloniod? if so i see 2 wires coming out of it and in that picture it says only 1 wire.

2)where do i wire up the knock sensor, or where is it located?

3)do i just extend the 2nd o2 wire to the ecu?

4)last but not least, the vtec is a simple ecu to solenoid, correct?


i know i sound like a big baby.

and if anybody can post pictures of the knock sensor and vtec pressure switch it will be very helpful.

thanks

1)where do i wire the vtec pressure switch? is it that green plug under the vtec seloniod? Yes if so i see 2 wires coming out of it and in that picture it says only 1 wire. other wire is ground.. i think the black one, run the ground to the thermostat housing where the other grounds are

2)where do i wire up the knock sensor, or where is it located? Back of the block up and to the left of the oil filter

3)do i just extend the 2nd o2 wire to the ecu? Yes

4)last but not least, the vtec is a simple ecu to solenoid, correct? yes

The vtec pressure switch is the green connector under the vtec solenoid. It has 2 wires because one goes to the ecu and the other goes to a ground anywhere on the engine. Also the knock sensor is a green plug located at the rear of the block underneath the intake manifold. I wired everything but the knock sensor on my b16a and it runs fine without it.
