What am I looking at? (1 Viewer)

This is the Speedo cable out of my ‘73. What sort of redundant s***tery is this??? The box was mounted on the firewall near heater blower. I should mention it came out of a ‘73 that had a 350 and auto trans in place. I’m hoping to install it on my all original ‘73.

Believe your have a emissions speed sensor. Box mounts to the firewall.

1975 FJ40 / speed sensor maintenance detector???

Need some help with information on this part, searching doesn't bring up much of anything. Does the speedometer cable run through this? Could it contribute to my speedometer not working?
