When I was wiring up my vtec sil and pressure switch, im pretty sure the black one was ground.

 

Ground - blk
VTEC wire - Green/yel (i believe)

 

isn't black and brown ALWAYS ground ............ or is that just me?

 

now one more question
when i bough the engine harmness I got it without the vtec pressure switch connector , and I was woundering if i can use one frome the stock d15b8 engine I mean I cut one for example the iab or any other connector that fits the vtec pressure switch and then put the wires together and ? is there any way I could do that

 

If you find a plug that fits, that should probably work.

It will, that's what I did. Yes black is ground. On the p72, does it ground to the chassis or A26?

 

does anyone know if the knock sensor has ground so I can connect it to the chassis or something like that

 

I just asked that question this morning. The answer is, that it is a one wire signal to the ecu, and the sensor grounds itself.
