2006 ML500 ME-SFI (ME) Control Module Location

On a 2006 ML500 where is the ME-SFI (ME) control module? On the ML350 it is on top of the intake manifold, not so on the ML500.

I'm having an issue with the engine not turning over. I've traced it to the starter relay not receiving a signal from the ME-SFI (ME) control unit. There are no scannable fault codes on my Autel scanner related to any engine problems. I've jumped out the starter relay (pin 30 to 87) and get the starter turning over when the ignition is turned on. I have 12.5v on the starter relay fuse 105 and the fuse is good. The starter fuse 122 is good. The starter relay is good. I don't seem to be getting the ground from the ME-SFI (ME) control unit to pull in the Starter Relay on pin 86. When the ignition key is turned on all systems come on as normal just the starter doesn't kick in when switched to start. The other question I have is what are the inputs to the ME-SFI (ME) control unit needs to supply the ground for the starter relay other than the key input?

Thanks for any help in advance.
