LS400Thailand

Help! So I looked at a LS400, 1994. It is said to have 75,000 Km on it. It looks in AMAING condition, engine sounds amazing and amazing trans. I used to own one many many years ago and since had the last of the LS400 97 and then stupidly brought a 2006 LS460L. That was a terrible choice. But anyay, There are issues and I am not sure if I will be biting off more than i want to chew.
Dashboard Cluster : the ABS, Brakes, Voolant, Parking Brake all remain on. The Fuel Guage reads zero and I also noticed the temperature was not reading properly also.
Now I have read a few post and see that the petrol level is a chip likely blown on the cluster as the petrol light does come on. Howver... ALL these lights stay on and I was only worried when i took it for a drive knowing this will be all replacement chips if I can find someone good to solder new ones on... However the ABS was not working. That was the final straw. Any thoughts please? I would have brought the car in a heartbeart if it was only the dash cluster (still worried) but then i managed to lock it up testing the ABS I did start to worry a lot more. Thoughts??
