[Peetronas]

Here's a picture I grabbed from the internet showing the cam sensor wire appearing just near the flash sticker.View attachment 121226

Thanks for that, was really helpful also I was considering to get this installation but this is so expensive. I got it the w202 chassis has a manufacturing issue with this one electrical wiring because of the high temp generates from the engine the wires are falling apart and the wires is shortened each other by time.
I’m sorry for so late response and much appreciate your help
