Adding a model number to your post will help make sure you get the right parts. Nothing more frustrating then paying for a part you don't need or can't use.
There were different model escalades made by fisher price/power wheels. There would be a decal in the battery compartment with the model number on it. If no decal you have a couple options. You could post a picture of yours or visit the hobbymasters website and search through their list of power wheel vehicle parts diagrams (free).
