I wanna Hemi in my 2010 TRX. Where can I find wiring diagrams for my truck?
I have looked and cannot find anything except on the Mopar website and they want a lot of money. I can find wiring diagrams for the 2005 Ram Hemi I want to use but nothing for my truck.
Also anyone know anybody that has done this swap in a 2008+ 4x4 truck?

Your best bet is to use the engine compartment wiring and PCM from a like year model Hemi truck. In other words, A CAN BUS system. In most cases, the terminals with will be in the same location (as in the BUS circuits) but don't assume all circuits will be the same. Key areas to focus on are the Main bulkhead connectors that connect engine to body wiring, because you have to consider how the rest of the communication network will interface, that's why I mention the right year model.
You will need access to the manuals, because you'll have your face in wiring diagrams for a long time. I do not know where to tell you to get all of them for free or little, but you can buy access to Chrysler Tech Authority or AllData. If you had a buddy at a dealership that would be even a sweeter deal. They could get you on Dealerconnect.
One more thing that comes to mind is the SKIM issue. A Dakota can still have a SKIM module and not have a SKIM key. Some of them were built with one as a interrupt for vehicle theft, but they don't serve a key function. So, take a look inside your steering column and see if one is there. If so, you can use a used PCM from the Hemi donor but the dealer will have to force the VIN/PIN change with their scan tool.
Good luck on your project. If you have any wierd questions, don't hesitate to ask. I like a good challenge. I recently had a customer in with a 2012 Wrangler with a 6.4 Hemi in it. The toughest issue he had to overcome was a quirk in the communication system. The scan tools didn't see the right VIN and it couldn't get through emissions. Expect some surprises along the way.

Thanks for the info. Im pretty sure my vehicle has the WCM module which has the immobilizer and RKE/TPM receiver integrated and all on the steering column. It definitely has the SKREEM keyhead FOB so that is the anti theft system I believe.
I was thinking that in order to get some good tunes from someone like a hemi-fever I would need to consider a 2003-2005 RAM hemi with PCM but I think that probably wouldnt work as I would have a body harness with a CAN bus and en engine controller without the CAN.
I guess a question would be is the PCM for he engine a standalone system or will there need to be a bus communication between the body harness and the engine?
I think I know this answer but I want someone to confirm.
I have done a few engine swaps in the past for Ford trucks (4.0 in Bronco 2, 460 in Big Bronco, etc...) but this will be my first Dodge and the other vehicle were pre-CAN
Thanks again for the info

You could take a gamble on something like Haynes, but they often don't have enough info in their schematics as well as some errors. Sometimes this doesn't matter too much if you're dealing with the factory drive train/electronics configuration since you can always do some wire tracing to make sure. Since you'd have one model of truck and the engine from another model, the color coding, connectors, and component placement (as well as many of the components themselves) is likely to have some significant differences, so you really should have some good reference material for each model. The "less than hemi" V8 configurations are not going to have the same algorithms flashed into the PCM, so even if ALL the sensor signals were identical between engines, the hemi wouldn't run as well as it would with the control algorithm designed for it.
