Thanks for the response. The truck does have a security system, reportedly a factory system. I'm waiting for my Marti report to figure out what this truck actually had from the factory vs. the dealer.
This was in the glove box of the '93 Lightning I just purchased. Since I got it at auction, I never got to speak to the seller to find out what this is. The truck has a factory security system installed so I'm wondering if this is related to that system.
