ps when I spent $60 for the '07 FSM I thought about another $90 for the Wiring manual but decided against.
No neet to protect anything when grounding that wire. It's protected already by the pulse module. The ECU literally only grounds it, nothing else.
Good thing you didn't, it's horrible. The Mercedes diagrams are much harder to read, but it's because they're that much more thorough.
