I have a 88 fj62 with 205k. I can't make my back up lights to work when go in reverse but can see that it momentarily switches on. Just before i get it into park position the back-up lights go on and goes off when in park. I changed the rubber bushing to clean up the sloppiness from the side to side play on the transmission lever(old ones worn out) but did not cure the problem. I was wondering where the neutral safty switch is and how do I adjust it? thanks alot for your input and advice.
