Hi,
where is the back-up light switch on a 1986 F-250 4x4? Did an engine swap (6.9 to 7.3) and trans overhaul on mine and lost the back-up light! Fuse has been checked.
Thanks for your replies

 

backup light/neutral safety switch combo on the C/6 is behind the shift lever on the trans. there are 4 wires coming out of it.
and it is a pain in the butt to set the reverse lights when it gets old.
i have converted all my trucks reverse lights to a dash mount toggle switch, because i use flood lights under the truck and in the light bars mounted on top of the trucks. they serve double duty as work lights as well as reverse lights.

 

TJC, Do you know where it is located on the ZF5?

if i remember correctly, it is in the trans, on top, back behind the shifter. and the neutral safety switch wires will have a small jumper across them so the clutch interrupter switch will work instead.

 

Shows on the drivers side just behind and below the data plate on my schematic.

Finally it was a bad contact at the trans neutral/backup electrical connection,whew,relieved!

 

glad you got it fixed without allot of head banging.
