So, while digging through a box of items from the previous owner, I discovered this box. Confused because my car already had a ford racing recalibration box installed, I went down the internet rabbit hole. I believe this to be a Dallas Speedcal? It does not have the sensor plug. Can anyone confirm and if so, is it even worth anything or should I just trash it?

These were pretty popular back in the day. If you just had like exhaust and gears you could get this for under $100 and you didn't need an entire "tune" I had one on my 01 GT back in the mid 00's- wired in line with the speed sensor on the trans, tucked in under the radio in front of the shifter.

That is how my current set up is. Ford racing which has three set dials to adjust out, depending on gears, wired and tucked in radio din. Just not sure why he would have had both. It appeared it came with the plug, but assuming it could be spliced into harness?
