wire relay???

[[[d a n n y]]]

i have no idea about this

what does this mean????

i mech says

i need to relay my headlight wiring harness as my HID needs more voltage to start up

can any1 give me a simple diagram of this and explain it to me?? plz??

thanks in advance

my guess at what that means is:

-your HID's are setup to run from the exsisting headlight wiring harness

-they apparently need more power from their own dedicated 'harness', ie fatter wires with connection straight to chassis for ground and battery for power.

however if you just run new fat wires to battery for positive power and to chassis or negative battery terminal the HIDs will always have power, and always be on until battery goes dead.

so you need a switch to turn the HIDs on and off!

so we use the original light switch in the car!

and the original wires that power the stock light bulbs to switch a relay to turn on the HIDs.

my guess is that there is a positive power wire and a negative ground wire that power the lights.

with the stock lights, when you turn on the lights from inside the car that switches a relay which inturn will allow positive or regative power to run through the circuit. ie it is setup either to cut pos. or neg. power wires.

you need to find out which it cuts out with a multimeter.

(actually this may not be nescessary)

whichever one it cuts out, this becomes the 'trigger' wire.

because when u switch the lights on and off inside car, this wire 'gets' or 'loses' power. while the other is unaffected, and will either have constant pos. power, or constant neg. ground.

how a basic relay works is like a switch, but you flick the switch with another electric circuit instead of by hand.

it sits in the middle of a circuit,

ie cut a wire and hook up the two ends to the relay, and doesnt allow the power to go through the wire unless another circuit, also hooked up to the relay is turned on, thus switching the relay and allowing power to go through the first circuit.

wat u do is,

you cut your new fat power or neg wire for HIDs and hook that up to the in and out of one circuit of the relay. so they are constantly OFF ie not allowed to work.

then you use the pos. and neg. that your stock headlights use, and they get hooked up to the other in and out of the other circuit on the relay.

how this works is when you flick the switch in the car to turn the lights on, the power goes through the original light wires and through the relay and switches the new fat power or neg wire in the other circuit of the relay, and allows power to go to the HID's turning them on.

i hope you can understand this and it helps and is actually correct,

Search for thread on having high beam and low beam on at the same time. There were a couple of in-depth threads about relays. I ended up hooking all my lights through relays like the person above said.
