Wiring up Vtec D16y8 to p28 ecu

Hey everyone im having a few problems wiring vtec in my eg civic i know there are 2 wires that i have to run from the ecu A4 D6

From my understanding A4 connects to the the vtec spool solenoid but where does D6 connect to ?

I have seen on rywire that i have to connect D6 to the vtec pressure switch but the D16y8 doesnt have on there is just a bolt where it would be also with the vtec pressure switch it has two wires comming out of it
so if anyone and enlighten me with this problem as its holding me back on getting this car finished :(

Any help would be greatly appreciated

Thanks

connect the VTEC solenoid wire to A4 (VTS).

Connect the VTPS wire to D6 and VTPS ground to the VTS itself.

ah so now i have to source a vtec pressure switch hmm
i have heard that you can just use a jumper from d6 to a4 then connect a4 to the vtec spool solenoid has anyone done this ?
