I had mine installed last night c/o Jason. Thanks to Supierrman's post, I decided to check it out. Installation took less than an hour. Here's what I observed:

1. I used to have dim instrument panel lights. Mas maliwanag na ngayon
2. Everytime I use my turn signal or hazard lights, my dome light would flicker as well as the backlight of my quartz clock. Ngayon very minimal nalang
3. More lively ang takbo ng engine ko ngayon. Feels lighter.
4. One of the major problems of the Vitara is the slow rear power windows. Solved.

P1000 ang binayad ko. So far, its the best upgrade I've done to my car in terms of bang per buck.
