I have 1991 f150 6CYL 5speed, and the speedometer and reverse lights aren"t working. Where does the speedometer cable and back up light switch enter the tranny ? I can't find a diagram anywhere. Thanks

The reverse switch is on the tranny if it's a m5od you will see one wire running to the top of the tranny, as for your speedometer I can't remember if it runs off a cable or a VSS. I think it's a VSS which is a sensor on the rear diff of your truck on the gear box.

It's a cable. All you have to do is look, it's not hard to find.

If he looks, he will find it. You can't find it when you don't look.

you just fixed your not broken ABS system with that part.

A FORD RIDER

what do u mean "not broken"...lol...

i got under the truck and saw the vss in the axle...is the part i bought going to replace that one?? if so good!!

and about the speedo cable...its the cable connecting to the vss right? if so yes i found it!

fordtrucknut

nope speedo cable does not connect to the vss.
vss in the 1987-1991 trucks, runs nothing but the ABS system.
