Hi all - I'm taking off a previous owner's LED lights and would like to wire back my original tail lamps. I don't know which wire goes where on this bulb tray! Does anyone have a picture of theirs showing which color wire goes to which tab? Please check out the picture of my light tray below.
Thank you! Which color wires go to which tabs? Thanks!
Easy enough to figure out if you have a voltmeter. Check the wiring to the LED lights and find out which wire reads 12v with turn signal, tail lights and reverse active. Then remove each light bulb and ring out continuity between each connector tab each light bulb socket on the incandescent assembly.
That's a bit too advanced for me, unfortunately. I don't have that tool or experience on how to use/where to contact. Hoping that someone has a picture to make this simple.
I could get a multimeter and try... could you please explain this process in a little more detail? I'm just not quite following based on your description; sorry.
Harbor Freight sells a digital voltmeter for $7 that's good enough for this task (Item 59434), and it comes with brief instructions. Use the 20 DCV setting to read the voltage on each of the wires. Activate the turn signal, connect the voltmeter black lead to some metal chassis point on your car, and connect the red lead to each of the taillight wires one at a time to see which wire is getting the 12 volts. Then do the same with with each of the other wires while activating the backup lights and taillights. Record which wire activates each function. The fourth wire that never reads 12 volts is the ground (common) connection.
On the replacement assembly, measure the continuity between each connector tab and the contact at the bottom of each light bulb socket. Set the voltmeter switch to 200 ohms resistance and connect the black lead to one of the tabs, and connect the red lead to each of the bulb socket contacts to see which one reads 0 ohms on the voltmeter. When a contact to bulb socket reads 0 ohms, that is the tab that connects to that socket. Then connect the wires identified above with the corresponding light tab. The ground (common) connector tab is the one that reads 0 ohms to all 3 light bulb metal bases.
@streborx Thank you very much! I really appreciate those instructions. That along with @shiann 's photo should get me squared away. Thanks again, guys.
