Brake light failure...

Well, it's a spoiler like this one:

I don't know if that qualifies as a spoiler (for lack of a better word) or not. As far as I know, my car is completely stock, except for replacement parts that have failed.

Okay, that is the pre-89 spoiler, so your Yellow Box should be the correct one. Well, I was hoping I could help you out with this but that's pretty much all I can think of...

You might want to use a Volt Meter and check for Voltage fluctuations out of the sending unit when someone presses on the brake. I don't know what the power is supposed to be, but if it's working there should be a change.

mines a 91 N/A and i had the yellow box. the way i understood it was that all N/A's had the yellow box and turbo's had the white box. could be wrong. its possible that whomever bought the supra new ordered an N/A with a spoiler...just a thought
