Hello guys, I need your help!

Does anyone have a wiring diagram for a '93 SC 400 instrument cluster? I think some pro guys here must have stuff like this. My cluster is doing strange things, and I want to get it repaired. It would be good to know the function of each wire on the 3 connectors behind the cluster, and the function of the circuits on the cluster board itself.

I'm experiencing the following things:

1. The "rear light out" light is always on when I press the brake pedal, but all the lights are working
2. All the lights are losing power when I'm using the turn signal, and both turn light starts blinking, the left one with lesser power...
3. When I put the shifter into "R", the two turn signal bulbs lights up on the cluster.
4. If the shifter is in "P" or "2" or "N", the corresponding light do not light up (all the bulbs are ok). In "D" and "L" its working
5. The airbag light do not light up (it should be on for 6 secs. when the ignition key is in the ACC position), but the bulb is ok.
6. Tachometer is not working, this is the most important for me

I've done search on the forum, but found nothing.
Please help me, post anything which could be useful.
Thanks guys in advance!

Thank you, but i'm an old guy and my eyes are not capable reading those pictures...

Is there a chance that you or someone else has a wiring diagram for a '93 SC400 in pdf maybe? (I have pdf for Supra/Lex ES, but everything is very different)

You may very well be old, it took you 2 yrs to respond

You need to click the pictures, they are in 10 mp scanned resolution, they get huge.

Here they are in full resolution, Stevie Wonder can see these.
