Not sure what years or models this fits as I cannot find a sticker on it.  It's NOS Mopar.

Came from the Shelby Development Center.  Looks to me to be dang near identical to a 1985-1987 Shelby Charger harness, but I can't say for absolute sure.  In any event, it's brand new, and the last time I saw a brand new OE 2.2 Turbo ENGINE BAY harness like this, that's seen zero heat cycles, was like 35 years ago.   We only have this one.
