I am working on a 2004 Dodge Ram, Original it had the 3.7L with the NV3500 5 Speed manual transmission. The 3.7L gave out after 300k miles and my dad wanted to put a hemi in the truck. Seeming the 5.7L was DBW unlike the 3.7L I managed to get my hands on a 5.7l from a 2004 Dodge Ram, Auto Harness, and everything for the TPS. Along with the wiring from the engine bay. I got it all installed into the truck, mated the 5.7L to the NV3500 and everything was good, fired right up, drove it around for a little while around the shop, Honestly this has been the easiest swap I have done minus the issues I am having now. My issue is I have constant brake lights when the ignition is on, brake works as normal when the ignition is off so i know the switch is good. I setup all the communications in the systems tab to match the V6 and it didnt help. I tried to switch the trans to Manual in the tune seeming this is a auto computer and I get no crank. Any help would be appreciated. I havent messed with the Hemis any with HP Tuners. I have been trying to figure this out for a week now to no avail.
