that's a very strange tems problem lol... i haven't heard of that one before... the most i could probly suggest is that there is a break in the wiring or even perhaps the tems computer is not plugged in
tems computer lives in left rear quarter, you will need to remove the interior panels to access it.. once you have the side panel off you should see 2 nuts which are holding the computer in place... feel in around behind there and see if you can find the wiring
also.. sounds like a normal tems to me... but the interesting thing is.. now i read it again.. the tems computer must be plugged in or else you wouldn't be feeling a difference... so maybe the wiring for the lights is broken or something?
i still have tems in mine
but not for long... i love my tems but new tems shocks cost too much for me at the mo so i'm putting standard ones in mine soon
sounds like you have an 87 that someone has upgraded the taillights on.... most american models look the same as the NZ 87... so...
north american supras all have electric antennas as well i believe
what i've posted in the body faq that describes the 87... that applies to 86-88 north american supras
was that confusing? lol
