Can I take a engine computer out a Durango to put in my ram pickup

They are specific, programmed for each car. You need to get it fixed or send a company the vin and buy one programmed to your truck. Here is a URL of the company we use, they are fast and have many on sale right now, Most times they send one out programmed, then after doing the replacement mail back the old one. I will post it below, Just copy & paste it and go threw the menu to find yours or call the phone number is what we do if we have any questions too.

They send you a prepaid return label for the core and when the core is received within 14 days then the lifetime warranty activates.
