Not sure what the other wires go to, maybe the air bag, regardless all instruments are working on the '89.

Thanks for your concern guy's. We did manage to fix the problem....It took us about four days of laborious work....We had to remove the harness covers and work our way backwards and forward, from the management computer, to and from the relevant 'sender unit' coolant temp, air temp, manifold pressure, lumda and oxogen sensor and from the controlled units, ie, ignition system, injection system, cooling fan set up and so on. We managed to identify the connections by following the identification labels printed onto the circuit boards.

We think that Toyota could make life a lot easier, if they used a standard wire colour coding and did not change that colour inside the loom....It is not un-common to see, as an example, a red with white tracer at one end and that may be joined to a blue with red tracer at the other end....If the loom cover is not removed and the cable inspected, you could not guess from what goes in, what will be coming out.

Hope this will be of help to someone somewhere.

Best regards

check in trunk for a fuel cut out switch, it shuts down fuel flow in case of an accident

The driver speaker cover comes off with Torx and after shining light through windshield, you will see two bulbs on a printed circuit film set apart from each other. You can reach them and twist and pull, clean contacts if bulbs not blown, replacement Sylvania 2721. There is also the reostat/dimmer knob that can be jiggled on dash, lower than the bulbs, each controling each bulb. I am in process of replacing mine with LED lights, which are brighter and come in colors as well. You just have to make sure the LED draws no more than 12 VDC as the alternator output is 14 VDC. Check out superbrightleds.com , there you will look for # 74 bulbs, which is same as 2721...I just came across the site today and thought, although your ????was a while ago, maybe this will give Saab Nation the ability to see at night....LOL
Peace
