I have a 93 ... same same ... that's something aftermarket. Alarm maybe?

I guess it could be.. it has a switch on it

It kinda looks like an old style motion detector. Have you traced the wires?

It looks to be lights of some kind maybe something that was on the truck new

That is not factory. I had a box like that in my '92 4Runner, it was an anti-theft device, starter disable. Mine was tied into the turn signal, I had to flip the stalk to flash the left blinker to get the truck to start. Sounds like a pain but after awhile it just became automatic. There was a switch on it like that that I could disable the feature, for things like valet parking. Maybe yours is turned off?

Oh ok thanks for the info. It's not wired up to the starter anymore

That's a factory self-destruct module. Very rare.

(That's a joke....)
