05 2500 wiring harness

Rebuilding one of this,need some help to locate some wiring harness in the engine compartment,that I do not have.

There is one harness that plugs into the firewall (maybe two sockets in one end),and goes to the middle of the engine block.
As I don't have a clear picture of this section,and couldn't find any by searching the site (went about 30 pages of this section before asking),I will appreciate if someone have some pics,or a diagram to show me what is really missing.
Could someone post some pictures of the driver's side engine compartment where the brake master cylinder/reservoir is (firewall view),with somewhat a clear shot of harnesses in this section,or direct me somewhere that have some pics?
Need more than one harness from this section (if anyone is kind enough to post a part # or the name by what it is known)
I thanks in advance for any help.

Mark,

My 05 (build date 4-05 W / G56 and metal inter-cooler) only has one main plug and a couple of smaller plugs.. Your dual plug setup was shown on the jake brake instruction when I did that installation..

Both of this pictures show a different wiring harness,and for the life of me I can't find the one posted by COLO RIVER RAM anywhere.
I asked a dealer for the other pictured harness and is about $380,kind of a killer price,isn't?
Any other outlets than dealer for this sort of stuff?

In any case,COLO RIVER RAM,could you post the information from your truck to see why it is different? ( I mean if you do not mind posting manuf date,and other pertinent information)
Thanks in advance

I do not have it,but the sockets look like COLO RIVER RAM's.
I mean one bigger socket and one small,the other picture show both the same size.

Your signature show you have a 3500 with a 5.9 cummings,I have to assume is the same as a 2500?
Or the harness is different PRECISELY because is NOT a 2500?

And you are correct,you already posted the manuf date,my bad I was blinded
and only focused on the pictures.
I'll keep looking,but so far,dealer only pull out the double socket harness when doing a lookup using the VIN.
And I need a harness exactly as it's shown in your picture.

No problem it is easy to get information overload here..

It is my understanding that the diesel trucks 2500 / 3500 all have the same wiring harness within each model. (that is why I showed my build date and listed the metal inter-cooler - that was a big change in models - the intro of the G-56, late "05") adding power accessories can be added by getting the sub-harness that plugs into the existing harness..

My Bullet has the wring harness in place for the running lights even though it did not come with them.. It would be to expensive for Dodge to put a different harness in each truck..this make's it easier for the dealer to do installs as well..

What specific harness you looking for? would some additional pics help?

The two plug setup is usually an 04 1/2 model year.
