Default V-AFC wiring

We just swaped a d16y8 into my buddys car and were running it off of a PM6, so its still ODBO. He has a v-afc to control the vtec, but i cant seem to find any info on the web to help me wire this thing up. Ive found something telling me what color wires are what, but im lost on where the wires go.

Ive went to the APEXi web site but that ---- doesnt help one bit. What needs to be done? I guess that some of the wires will be wired strait to the vtec syliniod and the others to the ecu.

Wire it up to the PM6 ecu? Hows that gonna work its not chipped for vtec or nothing. Its just a stock PM6

Right now the vtec sylinoid is not wired or nothing. Its just the CRX SI wiring harness on the y8. Is this ---- not possible or something i cant find this ---- nowhere on the interWEB!

After like four damn hours of searching ive found this.

How to Instal A'pexi VAFC in a CRX

V-AFC VTEC controller ECU PIN location
Red & Orange wire splice/connect to A15 (yellow/black)
Green wire RPM signal splice/connect to B15 (white1)
Pink wire VTEC signal output to VTEC solenoid (green/yellow)
Purple wire VTEC signal input not used on PM6 ecu
Blue wire VTM signal not used on PM6 ecu
Gray wire Throttle signal splice/connect to C7 (red/blue wire)
Yellow wire Pressure signal output cut/connect C11 ECU side harness
Si/Hf = white1 , DX = orange
White wire Pressure signal input cut/connect C11 ENGINE side harness
Si/Hf = white1 , DX = orange
Black wire Ground splice/connect to A16 (brown/black wire)Engine side harness
Brown wire Ground splice/connect to A16 (brown/black wire)has to be connected closer to the ECU

I know a good sell that tells you exactly how to do it. But you seem like a rude person
