aftermarket part ID

[Nitvid]

While at the local salvage yard I was searching for misc. GP parts I came across this aftermarket item in the car. Wires ran from the back of the unit to under the dash someplace, I didn't investigate further. Anyone know what this is or what it is used for?

Not a clue maybe under body lights?

It adds more horse pawa!

Yea I agree w/ dsmuts looks like a controller for leds or something.

Obviously it's a trailer brake controller.

Looks like the car was a BHPH car, after you'd make your payment youd get a code you had to put in to keep your car running for a week till you made your next one.
