Your drawing looks correct now. The valet switch is a bit confusing. Unless your customer specifically asked for it that way, the red wire goes to a circuit controlled by the ignition key, not a hidden switch. When the key is in "acc" or "on", things happen: PC should boot, monitor comes on, DVD powers up, amps come on(after delay)
well the reason i placed the valet switch on the ignition wire because as i understand it the PSU would have power feed all the time right from the battery but it wouldn't start though until it receives signal from the car when its in "acc" or "on" and thats what the acc "red" wire does.. it transfers this signal from the car to the PSU telling it to start. so i though placing the swtich on that wire would prevent sending that signal to the PSU when in "acc" or "on" modes if that switch was open
basically i did it this way based on my understaning.. so if there is a better way i would love to do it that way.
another problem am running into and that is my motherboard has a 20-pin socket and unfortunately when i ordered my OPUS i chose the 24-pin cable.. now according to this site:
CertTalk.com this is basically what i should do:
well i did that but the pc wouldn't start!!!!!!!!
