thanks for the diagrams. now who knows how to read these diagrams to translate them into english for me?

 

Your welcome, lol, but I feel like a dumb@ss in school who's been given an open book test an still blows the exam because he doesn't know what he's looking at.

 

lol, i have failed so many open book tests in EE. not to worry i know my circuits.

B should mean the wire is BLACK. and W-B means the wire is White/Black
and im assuming these are the diagrams for the supra, not the sc

ok passenger side:
you need to connect the labeled B on your seat as well as wire W-B to your car harness.
so, your seat should have these 2 wires to connect to your three(your cars).

So you would take the W-B wire and connect it to one of the three wires and the B wire and quickly tap it to another one and watch the light. i would connect W-B first. its better to guess correct the first time, like try and match up colors or use some common sense. if you tell me the three colors left on our car side i could prob tell you which ones to use. if it doesnt work then switch em around.

the whole part with the buckle switch should be done somewhere in the seat and you dont have to worry about that, it will just work, thats its job.

Driver side:
the driver side is a bit different. its a bit hard to read, basically you are looking for a single wire pointing out. and another ground wire.

possible candidates:
P for parking brake switch - obviously not it
STOP for stop light switch - whats a stop light switch is for?
DOME - obviously not it again
DOOR - probably not it again
there are a couple other ones i cant read but dont look like seat or belt

if i had to guess i would say try top light. if its the same color as the passenger side i would say its a damn good indication. or see which one is.
maybe its for stopping the seat belt light? lol.. that would be whack though.

anyone got a better res shot?

I dont even remember there being a light anywhere on the SC for the passenger seat belt. is there one? too lazy to go outside.

 

The diagrams is specifically for the SC... straight out of Volume 1 (of 2) Lexus 1994 SC300 Repair Manual (the massive eom Lexus one). The wiring should be identical in the SC3.400 for seat control and the info helpful to our community specifically. There is one light activated by either seat belt switch circuit.

 

I just assumed it was for the supra because the passenger ecu did not have power seat controls.

anyways, the only thing that changes in what i said is that the B and the W-B wires should be on the car part of the harness. so touch them to the wires left over on the supra seats according to color. and if theres only 1 wire on the seat, then try just the B wire. Drivers side still no clue.

im gonna go hop in my sc and check out this one light for both seats thing.
if that is true then you might have a really hard time getting it to work at all,
and im not sure if what i said will work. both seats might have to be right for it to work at all

 

OK, the passenger seat on my car has no indication light.
the light on the dash is for the drivers seat only.
with someone sitting in the passenger seat and not having the seatbelt on does nothing that i can see. i have a 95 sc300. maybe my car is bunk.
can someone confirm. i dont think these seats detect weight

 

i switched my passenger side first and the light stayed on...actually, damn, i didn't buckle the driver's side seatbelt to confirm.
