asr module location 95 e320 wagon
 

Hello,
I have posted before with great results, so I hope someone can offer me some assistance.
I have a 95 e320 wagon that is in need of a new ASR module. I have been told that I can change this myself as its basically just a matter of unplugging one and plugging in the new part.
I was told that the module is under the plastic shield behind the battery. The e-class owners Bible identifies the first module closest to the battery as being the ASR relay, but when I reference other photos it looks like the ABS unit.
Where is the ASR module? What does it look like, is it black plastic or metal. I need to remove the old one so I can reference part numbers to be sure it is a corect match.
Many thanks in advance,
James
