I have a 1988 toyota pickup with automatic transmission. The problem is when I place the transmisssion into reverse I get no reverse lights. The bulbs and sockets are good. Is there a switch on the transmission that is used for turning on the lights? Is this switch tied into the neutral start switch? Is there a procedure to check this switch to see if there is a problem? Is there a fuse in line some place that might have gone bad? I could use some help to troubleshoot this problem. thanks
