So, I wanted to find the ASD or fuel pump relay today so I could wire in something that would only have power when the engine was actually running, according to the docs the relays are located in the PDC next to the battery. However, all I can find in there are fuses????

I have a 2006 Quad Cab with the 4.7 v8 ... can anyone please tell me where the relays are hiding?

 

i'd think the relays should be in there with the fuses. they should be little square boxes about 1 inch by 3/4 inch and 1 inch tall

 

There are some larger items in there, but they aren't relays they are the larger capacity fuses. They only have two connectors instead of the four a relay needs.

 

Don't know about '08 4.7s, but look at the underneath or your fuse box cover.

In the hemi, there are a ton of relays in there.

 

The layout on the underneath of the fuse box cover only references fuses (which is all that is in there), this is really confusing.

 

On my 04 hemi, there are relays and other stuff UNDER the fuse box too!

 

Here's a couple of pictures I stole from Hammer... it shows how to do a high beam and fog light trick. The black boxes in the fuse box are the relays. I think this is in a Hemi, but I would think the 4.7L is very similar if not the same.

 

Thanks for posting the pics, my PDC is very different, it's like half the size and mounted at about a 40 degree angle next to the battery. No relays whatsoever

 

yeah I got an 07 and its the same way. No idea where relays are for that.

 

Hmm, I have a copy of the "2006 Dodge Ram Truck Workshop Service Repair Manual" in pdf format. When looking up the ASD or other relays in the index, the page states that it is 'located in the PDC', however, the PDC in the diagram is always the bigger style as in the photos above. The manual deals with 3.7, 4.7, 5.7 and diesel so I don't know why it won't differentiate? Maybe they changed the 4.7's PDC mid model year????
