Hello i recently put a 03 Cobra Trunk lid with drag spoiler on my 2002 v6 Mustang everything fit perfectly but when i went to wire the 3rd brake light up to the stock wiring harness the clips didnt match so is their like a wiring harness i can get that can connect the 2 ?
The Cobra harness is from a newer Mustang. The different years or the different models have different connectors. At this point all you can do is cut and splice. You'll have to cut the harness end off your v6 lid and cut the end off the Cobra lid and splice them together so you can plug it into your trunk harness. Or you can do the right thing and just put the spoiler on the v6 lid and bypass the wrong trunk lid altogether. You'd need to drill in a few places to mount it.
