Hello All,
I am not sure if anyone has already shared this. Below is the link where you will find the workshop manual and wiring diagram for Maruti Suzuki Wagon R. I could not upload it here as the pdf file size is bigger and also the download is 65 MB.
Suzuki - Wagon R Shop Manual | Auto Repair Manual Forum - Heavy Equipment Forums - Download Repair & Workshop Manual
The manual seems for old models but may provide some basic information for wagon r users who have latest models. For downloading you will have to create a login on that website. The download is free. Enjoy!!
Doesn't appear to be working. If you can access it, could you upload it to Google Drive (or similar service) so we can get it too?
