No power to power windows

Have you actually checked for power at the driver's master switch?
I don't think there would be a window relay, there is probably a power window circuit breaker in the instrument panel fuse box.
If no windows work, pull the master switch out and check for one hot wire with key on. If none, check for broken wires in driver's door opening. Your ground for the windows will be in that group of wires too. Both must work for windows to operate. If you have power and good ground at the master switch, and no windows work, probably a bad master switch.

Headlight relay

its probably the combination switch on the steering column, as these vehicles don't have a relay for the headlights. The most common problem with the headlights are all the grounds that are used. Check all your headlight grounds, and if you still have a problem, its your combination switch.

Parking brake switch wire on a power acoustik double din

this use to be simple for most units and yes it would work, however, manufactures became wise to this idea and placed a relay inside the unit that must be reset to prevent us WISEGUYS from doing so, but i do not know if this is the case with yours, if it is then you can run a toggle switch between the unit and the ground in order to reset this relay as needed with a flip of the switch

1989 ciera orange wire going to the oil pressure switch was accidently grounded. Will turn over backfire but not start . Fuel pump won't power up. No power to fuel pump relay. Took relay apart manually...

You didn't post an engine size but you are correct in thinking there is a fusible link that blew when you grounded the orange wire but there is also an inline fuse that protects the oil pressure switch and the fuel pump relay. It is usually located on the firewall.

You can check the fusible links near the starter for continuity. If one of them is burnt up start there by replacing it. If none of them are bad you will need to find the inline fuse. At least the 3.3 liter engine is set up this way.

Dvd player to work while in motion

This can be done with a toggle switch or a relay.
**Toggle** Connect one side of a toggle switch to a ground and the other to the light green wire on the unit (parking brake input). Once the vehicle is started, just flip the toggle and apply ground. Taa-daaah.

**Relay** (see image)** This will bypass the parking brake automatically every time.

Bypass ebrake with relay on a pioneer avh-p5700

Go to any auto parts store and purchase a four wire relay and wire it up as follows: The relay will have numbers written on the bottom for each pin. The wire from the parking brake from the H/U to 87. Ground to 85 and 30. Remote from the H/U to 86. This will give you an automatic bypass to the DVD lockout. If you want to just put a switch to do this manually you can also. Go to Radio Shack and buy a momentary push button switch, part number 275-1548. Take the green wire coming out of the unit. Strip the wire, and attach it to one of of the pins on the relay switch. It doesn't matter which one. Buy a standard 16 gauge wire from Radio Shack and connect it to the other pin on the switch, then connect the other end of it to a grounded connection on your vehicle. Now, when you play a DVD, the warning screen will come on. Just press the button on the switch and it will go away, since it tricks the receiver into thinking you have engaged the parking brake. Like someone said before, it is illegal in just about all states to have a dvd or other video playing if the driver can see it and the car is moving. This method is used because the lockout not only keeps you from seeing videos but also locks out some features which many feel have nothing to do with safety and they need it.

Need headlight wirning diagram

In the case of headlamps and tail lamps, The switch supplies the current through a relay.Relays tend to fail when set up too long. The relays should be under the hood. The ligt switch cannot handle the current load required and could be damaged by overheating if wired direct to lights. Look for the relayThe dead fuses should be identifie near or at their location if not under the cover if so equiped. Food luck. Remember, each lap has its own grounf, including the relay. So, your batt eng ground and engine to body grounds are very important.
