Scion TC LED Tail lights not working, help!

    So I ordered a pair of LED tail lights from this website.

    https://www.protuninglab.com/alt-yd-tstc04-led-bk.html

    They are '2005-2010 Scion tC Coupe Euro Style LED Tail Lights - Black' for my 2007 Scion Tc.

    I took off the bumper and everything. Installed the headlights and they worked... for like 5 seconds until they blew out a 10 fuse underneath my steering column when I was checking all the turning signals, reverse lights and break lights.

    I read other forums and tried swapping out the connections and trying different combinations. Through the different combinations only the brake lights seemed to be affected. Either one worked, they didn't work or they both worked but ended up blowing a fuse.

    It's a saturday so I cannot contact the company that I bought the tail lights from at the moment. I was wondering if anybody here would have some knowledge on what to do.

    I have been doing a bit of digging and came to the conclusion that maybe I need 50W 6Ohm LED Load Resistors installed onto my tail light harness. I will love some feedback please.

    So I ended up finding the problem. I'm a rookie and have never done this before. All I did was unplug the battery and then install the tail lights. https://imgur.com/a/NZOFJ

    hey Tripsy, welcome to Club Scion tC (CSTC)..

    Good news you got your tail lights working! So how did you get them working? Was a plug backwards? And hey we were all rookies/newbies at one time, gotta start somewhere!

    Thank you for the welcome. All I did was unplug the battery, hook up the tail lights and connect the battery to test them. If they weren't working properly then I unplugged the battery and flipped the connections from the tail light harness to the aftermarket tail lights until everything worked. And that was that. It was something so simple but I learned a lot.

    Here are some imgur picture links to my new LED tail lights.

    interesting about re-hooking up the new tail lights.. Sounds like the right connection was made! Congrats! Thanks for the pics, they look awesome.. Nice and clean!

    glad you learned a lot! Hey I gotta ask, how hard was it to remove the original tail lights? I know there is a clip holding them in? I haven't taken mine out yet.

    It was really easy. First, you need to take off the bumper. The bumper has two screws where the hatch meets the bumper. two screw in the rear wheel wells. And 4 push pins underneath the bumper. Be really careful when taking the bumper off near the head lights, the tail lights have plastic ledges to aid in the securement of the bumper to the car, they can break off easily if you're not careful. However, if they do break I don't really see an issue, the fitment shouldn't be any different.

    Next, on the inside of the hatch you need to remove the covers to the tail light harness. There is a latch that holds the cords nice and neat but you can just pop that right off the screws, you will be able to see what I mean if you take a look inside. Unplug the tail lights and remove the 3 screws holding the tail lights in place. And then you just pull the tail outs out by hand straight back. The harness and the tail lights will come out in one piece.

    I think the hardest part is the bumper removal. Here's a link that helped me a lot. Just in case you didn't know. Also, to everyone who might look at this thread.

    I knew some of how the tail lights came out, but thanks for that "hands on" view of how it is. Oh ya the plastic ledges on the bumper cover itself, ya those are always so thin and the clips never want to let go! So take time and wiggle it out, got it! I have seen inside when I replaced the light bulbs of how it looks.

    Thanks for the update!
