Anyone know where this is on the automatic transmission? My backup white lights don't work & I failed the Massachusetts Safety Inspection. I took off the shifter T knob and the wood plate and cannot find it there. Someone told me it was on the side of the tranny under the car on passenger side. I have the car on jacks now but still cannot find it.

The Fuse (F12) is has power to it. The wires in the trunk lid have 12vdc to it when reverse gear is engaged and 0vdc when taked out of reverse, yet they won't light up. This confused me. I took the bulbs out and tested them - they are ok. Back to the wireing - If they have 12v why won't they light up? Could it be that a digital volt meter (being sensitive) "senses" a trace of 12vdc running to it via a faulty switch (which I cannot find) but doesn't have enough AMPS to light it?

Any help would be appreciated - thanks
