fuel pump relay location
I have a new fuel pump relay for a 91 300SEL. I can not find its location in my car. I have been told its in my fuse box, I assure it is not. I was told at my shop that its between my two firewalls next to my MAS relay or OVP, but I can not find it. I have read in this form that it maybe part of the MAS relay but found nothing conclusive.
I have attached a picture. Not too many 300SEL's in this board in appears but if anyone can help I would be greatful.
