reverse lights stop working

Not entirely sure about the 240SX but the 300ZX has a Switch in the Transmission for the Reverse light that commonly goes bad.
I remember there was a switch like that in my 1982 Datsun 200SX too. I had to replace the one in my 300ZX and now it works perfectly.
The 240SX is probably the same. That’s something you may want to look at

these switches are also commonmly found in the shifter assemby (or console).
or you an bypass the whole system and use a relay and switch…
makey your own for $25.00 and some time…its no big deal…really!
