Can't seem to locate backup light switch on a 700 R4 transmission, lights will not go on and I do not see a switch on the trans anywhere
I had the same problem. My backup lights wouldn't come on in when I put the auto. trans. shifter into the Reverse position. They WOULD come on briefly as I moved the shifter from Park position into Reverse, but would go off again when the shifter reached the Reverse detent. I got the solution from the Haynes service manual, in which the relevant switch is referred to as something like the neutral safety switch. Check on top of the steering column close to the firewall. Set the parking brake, then move the auto. trans. shifter into Neutral position. Get under the dash and rotate the neutral safety switch clockwise as far as it will go. Then move the shifter into the Park position, and your switch should be set. If the backup lights don't come on now when the shifter is put into Reverse position with the ignition switch 'on', there may be another problem.
Should be under dash on steering colume.

HI
Yeh I need to find out the reverse light swich is on a 88 silverado that I imported into Australia.
Over here we need to have totally seprate indicators and brake lights.
so I am using the reverse light location with amber globes for indicaters, and fitting seperate reverse lights.
cheers
