How do you remove ECU (W221)
I am not sure if the ecu setup varies from the 06 to 07 but I can't figure out how to remove my ECU. I have a trx and hex set and removed the ecu which is integrated with the black plastic cover but how do you remove the 5 or so sets of wires going into the aluminum ecu caseing?
Thanks
Thanks

The plugs have a certain order in which tehy must be pulled and replaced. If you go to the Renntech website, they should have instructions.
