Help me connect LED plate lights, please.

[stopintime]

I have these LED Tag bolts from http://www.customdynamics.com/illuminatorz_licence_plates.htm

Some time soon they will be part of my no chop/ plastic chop/ paint job.

My questions: Will both red wires connect to plus wire from the stock plate light / both black to negative?
                     Can I expect to see one red and one black wire to the plate light - if not, how do I know which is which?

Connect both positive wires to the red positive wire from the stock harness and both black wires to the black ground wire from the harness.

I checked and there seems to be one yellow and one black. Yellow = positive? (as in the red on the LED bolts?)

[metallimonster]

Its easy, just connect both reds to one yellow and both blacks to black.  I used disconnecting crimp connectors that have the shrink tubing built in.  That way you don't have to cut and rewire if you have to remove the plate.   You just diconnect the connectors. 

By the way these look really cool at night and I get a lot of compliments on mine.  I wish I hadn't waited so long to do them.


While the positive wire can change color from manufacturer to manufacturer black is almost always negative.

Thanks guys

That my friend, in the Automotive/Motorcycle electrical world is a very dangerous comment, I have seen many car and bike companies use black as a positive lead, never assume a lead is + or - until it is confirmed by a wiring diagram or a multimeter.
To many times I have seen people blow up or melt down electrical parts/accessories/ECU's because they assumed the + or - wiring because of wiring colour.

Always check and be safe 

MetalliMonster, please don't take offence at my comment, I'm not trying to give you a hard time, granted in this case it most likely is a - lead, but in to many situations I have seen it end in tears.
When it comes to anything electrical, always check and never assume.

+1. VERY dangerous. In household electricity, you never know what you run into, so its always best to check all wires.
I would check the wiring diagram. Some devices have 2 of the same colored wires becasue it doenst matter which way they are wired.

but since both your bike and the plate are manufcaters item, its a pretty safe bet. but i would always double check the wiring diagram before making an assumption.

on your bike it should be yellow hot, black ground (atleast it was on my licence plate light) If there are 4 wires ( assuming its more than 1 light cluster/module) then just pair up the colors on the license plate light and connect them to the approriate wire on your bike (again, black is ground on your bike, by ground , I am also refering it to as negative)

German vehicles, brown is ground.  House 110 wiring, black is hot, white in neutral except when someone makes a mistake.

No worries here.  I guess I didn't specify vehicles in my statement.  While older Audi's use  brown for negative they are starting to go to black.  Yes should always check but since this is an just a two wire LED it really would work either way.
