I'm curious as to what these go to if anyone has an idea. One appears to be a serial cable (diagnostics?) of some kind and the other I have no idea. I have a JWT ECU (not installed by me), and I'm wondering if maybe they have something to do with that. I know the hole they're currently coming through is obviously not factory, but I'm wondering if the cables themselves are OEM or aftermarket. I can't find any identification save for a random string of numbers which I've googled to no avail. I've texted the previous owner with the query and pictures, but I think he's finally getting sick of me . Any help is appreciated and if you need more info, please ask. Thanks!

Aftermarket. Very old car phone.

Interesting. So I assume the smaller cable was for the antenna? Now i'm going to have to rip it out.

Being 34, you'd think i'd have known that, but car phones were a bit out of my families budget. The first cell phone any of us ever had was after I'd graduated high school.
