WTF is this in my trunk

[MR 325]

Yes that's the check control unit and yes you need it.

[MR 325]

Thats right next to where the jack goes right? If it is then my 89 definitely doesn't have that.

Your 89 definitely has it.

Your 89 definitely has it.

I'm going to check tomorrow, but I have my trunk completely gutted and dont remember ever seeing it.

Edit, my brake lights check light goes on all the time, so maybe mines missing/broken.

I've already pulled the check panel, and all the associated wires. there were two wires that ran back to that box that I've already pulled.

[MR 325]

I'm not positive but I could have sworn the lights will not work without that box.

They dont if I unplug it, so I left it, just erased the two wired from it that ran to the check panel
