What is this thing?

What is this thing? It attaches behind the TPS sensor. It is hard to see in the pics but it ha a red and green light on the back. Thanks.

There were throttle response enhancer Or TPS signal smoothing gadgets on the market. If there is no part number on it and no maker’s mark, that’s my wild guess.

The label is wiped. I can find no other markings on it.

What year? I assume it's a 5.0?

Casper's TPS Enhancer

They still make them for other vehicles, but have been discontinued for the 5.0. It's snake oil

Thanks for the replies. It is a 1989 LX 5.0.

What was it supposed to do? How do you “enhance” the TPS?

At 70% throttle it bumps the tps voltage to max to fool the ECU Into thinking it’s at WOT. Changes fuel and timing slightly. It’s just tomfoolery.
