I recently purchased a 2007 Scion Tc used about a month ago. I ordered some new tail lights I'd like to install. But I cannot figure out if I need a wiring harness for the installation. I presently have stock tail lights installed with stock bulbs.

Here's the tail lights I bought: http://www.ebay.com/itm/131480665531?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT
It has one cord running out from the LED part of the tail light and that's it. The other two ports on the tail lights are empty (I'm assuming to just plug in the stock bulbs and wires).

So my question is more simply put: do I need any extra parts in order to hook up my tail lights?

I am very new to Scion and modding them so try to keep the language simple and if you can give me a specific item that I can purchase on ebay or similar site. I have heard I may need a wiring harness but I'm not sure if that's true.

I GREATLY appreciate your help! Thank you!

 

I'm not familiar with that specific set of tail lights, but generally you shouldn't have to buy extra parts to make aftermarket lights work.


I think your assumption about it using some of the stock wiring harness might be correct. You should contact the seller as well for some insight if you still can't figure it out.

 

Here are some pics...

 

You'll notice Brake/Position light makes sense since the connector on the tail light already exists and can be plugged into the socket from the vehicle. However, I don't get the "install the function of Turn signal light" because there is no such connector from the tail light that looks like that!? Am I missing something? Since the only harness is being used for the brake light, this is what makes me think I need another for the turn signal light.

 

You do not have LED turn signals, that install paper must be a catch all in case that company may make another set of lights that are fully LED. Make sense? So plug in your turn signal and reverse bulb and connect the tail light as directed (disregard the turn signal portion of the installation manual) it should work.

 

Thank you guys so much for your help! So if I understand you correctly I shouldn't need to buy any extra harness or anything? Just take out the old tail light and plug in the new one with the stock bulbs?

 

Correct. You use your stock wiring. No need to buy anything else.
