well i just installed the 89+ spoiler on my 87 supra and the plug just snapped right in. start up the car and it's throwing a tail light code on the dash? my tail lights still work and i checked some fuses they were all just dandy. am i missing something is there a seperate fuse for the 3rd brake light or did i just buy a fubar wing?

you need the lamp failure sensor (yellow relay box mounted under the l/h taillight) from an 89+. yours is trying to look for the regular bulb circuit instead of the led in the 89+ spoiler. different resistance i believe.
If you're a DIYer you could replace the resistors with pots and then just tweak until the failure module stops tripping. I haven't looked in one of these in quite a while so I can't be more specific right now.
somebody in the know has to get their hands on both boxes and look at the resisters, it would be an easy job to swap resisters to make it an 89+ box...
