• Wiring included: diagrams, connector pinouts and component locations

• Questions answered by a person, not a chatbot, before and after you buy
• Online since 2015, rated a Google Top Quality Store

What this manual has that the owner's manual does not

The owner's manual stops where the repair starts. The factory repair manual picks up from there:

• Owner's manual: controls, warning lights, maintenance schedule, fluid types
• Factory repair manual: how to take parts out and put them back, the torque for every bolt, fault codes and complete wiring diagrams
