TRD spoiler brake light keep blowing STOP fuse

[joe85922]

Yesterday I installed the the TRD spoiler. I unplugged the stock 3rd brake light 2-pin connector and welded the two electrical wires from the spoiler onto the 2-pin connector. But when I stepped the brake pedal, the 10A STOP fuse just blow out. I am thinking there might be a problem with the spoiler wires, but I don't know! Thanks for your help!

Definitely sounds like a mis-wiring job. The fuse could blow because you have wires crossed or whatever's connected is drawing too much power thus the fuse blows to prevent damage to whatever is drawing power. There might be some electrical components (like resistors) downline from the fuse that need to be in the electrical circuit before connecting to the spoiler. It doesn't sound right to have have to cut and solder wires to install your spoiler.

You shouldve just tested it before you "welded" the wires, make sure you dont have the power and ground wires mixed, if they are on right then make sure that they arent touching each other, and make sure the wires on the spoiler arent exposed, if for some reason the power wire hits any metal itll short
