I ahve a ITR wing with the Brake light. so when i wire it, should i wire the black wire from the spoiler to the black wire from the trunkharness from my old spoiler? and the same with the red wire as well? its simple. i'm just retarded and not good with electrical stuff AT all. ahah. Let me know soon, im going to install in like 10 mins. =] Thanks for the help.

Temporarily hook it up before installing the wing to make sure it works. If there's no connector, just use crimp connectors as a temporary connection, or even wire nuts.

With only 2 wires, it will either work or it won't. If it doesn't work, swap the wires and try again.

 

how do you plan on installing your fake itr wing, if it doesnt have any bolts coming out of it?.. real itr wings dont have 3rd brake light.. just an fyi..

 

the brake light bulbs run in series, so you can tap into any of the wires on the brake light section of the tailight harness with the red wire off the spoiler,(you can also tap into the 3rd brake light as well) and just take the black wire from the spoiler and give it a good ground. when the brake lights see voltage so will your spoiler light.

just do a clean job, give yourself enough slack so when you open and close the hatch that your not stretching the wires and what not. and dont leave the wires just hanging around. wire loom and hiding them will be the best route

 

OP said he used to have a trunk spoiler (OEM I guess), so all the wiring should be in the hatch already. If not, the wiring will have to run all the way up the side of the rear glass, into the top edge of the roof, and back down the C-pillar and along the side back to the harness for the brake lights.

 

Sorry i do'nt have money to buy a OEM ITR wing -_-. and yeah i screwed some bolts from the bottom up into the wing. Got the LED to work.. and i KNOW OEM ITR WINGS DONT HAVE A THIRD BRAKE LIGHT. -_-

Thanks everyone tho.

and since i'm poor. i bought some thin foam and cut it the shape of the bottom of the spoiler so when i bolt it down, it wouldn't have contact with the trunk.
