Can anyone tell me what part this is connected to the battery and looks like it runs to the engine. I need to replace it but having a hard time finding out what the part is. Is it a fuse? Can someone please help me find this part to replace?
Looks aftermarket. You will need to trace it and see where it goes and why it is there. From memory, my 2000 GTX DI only has 1 solid red wire coming off the positive terminal.
