Hi Fellows

I was looking under my truck and I found and electrical item that looks like it was attached somewhere under the hood...drivers side.
Looks like a relay of some sort.
Part number on item is 56007078 50732.
I don't know if this a common number on all 2004 555 305's.
The only thing different from stock is when they changed to an intank lift pump some months ago.
I am wondering if this was part of the old system.
It looks like it was originally bolted somewhere as it has a mounting tag.
Whoever was working on it hung it with a wire tie that finally gave away.
I wish I could post a pic, but I don't know how to.
Quite a brain teaser...can anybody help?
No hurry as all running ok and I restrapped this thing in a safe area.
Thanx in advance.

 

Well, where do the wires go to?

Have you had the truck since new?

 

I know this is a really old thread but I'm not finding much about this relay anywhere else. I'm is mounted in the same location, it has a power wire with an in line fuse and the other wire go to a connection just behind the fuel bowel
