Need help with part identification

[DayRaccoon]

I am doing some work on my 1976 FJ40 and discovered this black box attached to the firewall. It appears to be connected to the electricity, but the other end is not connected to anything. I can't find much online about it or in my Haynes manual, so I am hoping to get some insights here. Thanks in advance.

Maybe try posting in the 40 section?

Agreed on checking in the 40 section 40- / 55-Series Tech - https://forum.ih8mud.com/forums/40-55-series-tech.8/ That other end looks liked a speedometer connector from a 40 series, so maybe it has something to do with a speed control?

Perhaps @OGBeno can move this thread to the appropriate forum?

what does a detector do anyway?..!

It triggers the "EGR" light on the lower dash - basically an analog mileage-based switch as a reminder to service the emission system. Flip the switch under the cap, and it resets the light.

EDIT: if your speedometer works, someone may have bypassed it with a one-piece speedometer cable.
