Hello guys, I could use some help in finding out what these cables are for. I've recently purchased this celica and I'm currently working on replacing/repairing the suspension and brakes. The car starts, shifts and runs fine. But there are these three cables that I can't seem to find where they should be connected. There are no error codes on the diagnosis. One is near the filter box and seems to be going under the intake pipe. Other is near the fuse box/battery and seems to be running into a harnes that runs behind the light. The last one is part of the harnes that runs from/to the alternator.

It's a 1990 gen 5 ST182L celcia 2.0 GT-i 16 with the 3sge engine and a 5 speed manual. Any tips or help is appreciated
