I just installed the new jw speaker 8800 evo 2's in my 88 fj62. In fact mine were plug and play. I was ready to encounter some problems, but I just straight swapped em and they were good to go. Jw does make the new evo 2 with heated lenses as well btw. Also my high beam indicator light does turn on in the dash. On the other hand lows go off when brights come on, but I don't see that as an issue. I know this didn't really help others solve their mystery wiring issues but idk maybe mine was rewired, I don't know what to look for. I can take a peek and report back if it helps anyone.
