The instruction the number on batteries. They’re not visible enough enough and how you put them in order for a specific car and how to route the cables, positive and negative on the battery. for example Toyota Camry hybrid 2009 I have a hard time routing the negative cable. because the design of the battery is different from one to another.

Only issue is it did not come with any information manual to guide the installation. It is not clear how the safety disconnect is supposed to be wired, so I connected it at the only point possible, but the plastic terminal covers had to be cut. A short jumper wire was included but I do not understand its purpose. Otherwise, the installation was straightforward. The modules are numbered 1 through 14, although the numbering is opposite of the official battery block numbers. You will see how it must be arranged to connect to the wires. There are attachment clips at the proper locations for the existing temperature sensors. I screwed the modules to the bottom of the assembly with the old screws, but it would have been nice to have 2x more screws to fill all the holes. I did not include the compression cage because it is not needed and I could use it with the old batteries. Hopefully the airflow is okay. Also included was some big washers and two nuts with unknown purpose.
