How would i wire up a bosch relay to take a (+)signal, and boost it from the battery to spit out a amplified (+) signal.

Well, what exactly are you trying to do? If you are trying to turn a low level input to a high level output(not neccessarily amplified) it would be: 85 + activation input, 86 ground, 30 Constant +12V, and 87 + output.

im upgradeing my headlight wireing. I purchased a new set of 9004 plugs with 12 awg wires so all i need to do is take the original power signal, run it through a relay then feed it back out through the 12 awg wire into my bulbs.

im guessing it would be the same relay set up as if i were to be adding a 2nd ignition relay to a car starter than only has 1 output. am i right?

So you just want to boost your headlight wire? ------------- ~The Rookie~

Relays dont amplify they use a small amount of voltage or current to control a larger voltage or current.All they are is an electric switch.

whell, , i want to take the wimpy lil signal from the factory wires, , and isolate them and power them directly from the battery which is a more realistic to power high power headlights, , get what im saying now??

thanks! Also, , just wondering about the ground wire on the head light, , should i permanently ground it, , or should i use a relay set up also? triggered from the factory ground wire? ------------- 2003 Chevy Avalanche,Eclipse CD7000,Morel Elate 5,Adire Extremis,Alpine PDX-4.150, 15" TC-3000, 2 Alpine PDX-1.1000, 470Amp HO Alt.

If the ground wire stays grounded when the high beams are on just ground the wire on the new harness.If it doesnt (ex. low beams go off when high beams are turned on)use the same relay setup but be sure to change the polarity on 87(change to -)and 86(change to +)
