What are the pin assignments for the Ford Tripminder connector C705?

Pin 1: blank; Pin 2: blank; Pin 3: circuit 296 accessory (white/purple stripe); Pin 4: circuit 19 instrument panel lights (lt. blue/red stripe); Pin 5: circuit 54 battery power (lt. green/yellow stripe); Pin 6: circuit 305 fuel flow signal (lt. blue/pink stripe); Pin 7: circuit 57 ground (black); Pin 8: circuit 150 vehicle speed signal (dk. green/white stripe); Pin 9: circuit 57 ground (black); Pin 10: blank.

What fuses power the Tripminder?

Three fuse panel positions feed it: a 5A fuse (position 17) on circuit 19 LB/R from the headlamp switch, a 15A fuse (position 8) on circuit 296 W/P hot in run or accessory from ignition pin A1, and a 20A fuse (position 6) on circuit 54 LG/Y battery power fed through a 16 GA orange fusible link and circuit 38 BK/O.

Where does the Tripminder get its fuel flow signal?

The fuel flow signal comes from EEC pin 34 on circuit 305 LB/P (lt. blue/pink stripe), entering the Tripminder at connector pin 6.

How is the vehicle speed signal routed?

Circuit 150 DG/W (dk. green/white stripe) at Tripminder pin 8 runs to the speed sensor (without speed control) through C705, to the speed sensor (with speed control) through C3012 on 57 DG/W, and to the speed control amplifier through C3013.

Where does the Tripminder ground?

Ground circuit 57 BK passes through connector C3015 and splice S904 to ground point G902; pins 7 and 9 of the connector are grounds (black wires).

This document is a Ford Tripminder (trip computer) wiring diagram, drawing number K6248-E. It shows the complete circuit for the Tripminder module including its power feeds: a 19 LB/R circuit from pin 1 of the headlamp switch (through a 5A fuse), a battery feed via a 16 GA orange fusible link and circuit 38 BK/O through connector C403 to a 20A fuse (circuit 54 LG/Y), and a hot-in-run-or-accessory feed from ignition pin A1 through a 15A fuse (circuit 296 W/P). The diagram traces grounds (circuit 57 BK) through splice S904 to ground G902, the fuel flow signal (circuit 305 LB/P) from EEC pin 34, and vehicle speed signal (circuit 150 DG/W) routing to the speed sensor (with and without speed control) and speed control amplifier via connectors C705, C3012, C3013, and C3015. A pin table lists all ten pins of the Tripminder connector C705 with circuit numbers, descriptions, and wire color codes, and a connector face diagram shows the physical pinout. This is useful for diagnosing Tripminder power, ground, speed signal, and fuel flow signal issues.
