I wrecked my grandmothers 1997 toyota camry le 3 years ago. It has been sitting in her garage up until a month ago. The passenger fender sliced about 30-40 wires on the harness. Which I have been soldering back together. I have all but 3 wires connected and am not sure what else to do. When I start it, it runs fine until it takes a big gulp of power and the car nearly shuts off. My father and I think its form the fans not turning on or maybe we mismatched some wires while we were putting them back together. The dash board seems to have no power either. The lights will turn on showing if there's problems but it doesn't read how much gas is in the tank or how many miles are on the car. The blinkers and hazards don't work either. And the final problem is the linkage to the transmission is off and I can't find a part to put it back on. Any help anyone can give me would be appreciated??
