I found something on my truck, what is it? I'm fairly certain it was installed by one of the previous owners :P

I'm assuming its some sort of immobilizer that has been disconnected.

 

Reminds me of a headphone jack. I really don't know. Was it connected in some way to the CB it looks like used to be there?

 

Its possible it looks like one to me too. I think there used to be a brake controller next to it not a cb, the PO liked his brake controller so much he took it with him :P The wiring on this "thing" goes up underneath the steering wheel and also into that weird circuit box.

If it helps anything I found a really old sticker on the circuit boards box that said
"Secure Recognition Systems Inc. 1994-1995 Version PK 1.5"

Meant nothing to me and couldn't even find anything on google except a one man business that went out of business in modesto CA

 

Hi

It's most likey an immobilizer, the owner would have a coded jack plug to insert into that socket, works similar to a Ford PATS key.

Thanks for the information, quite unfortunate the guy who sold me the vehicle didn't give ne the jack
