'78-91 similar

Terminal "I" is the dimmed output to the instrument cluster & dash. At some point, Ford renamed the wire between the switch & fuse from 19 LB/R to 294 W/LB to distinguish it from the rest of 19 LB/R.

The only significant difference between '92-96 and '80-91 is that the MFS's DIMMER switch replaced the older floor-mounted stomp-style beam select switch, but (other than Flash-To-Pass) they perform the same function.
