I recently swapped a 2002 4.7 into my 2005. The 2002 was a doner truck I had bc my son wrecked it so I had some time and moved motor, com, wiring harness and the fuse box all over to the 2005. It was alot of work but the engine starts and runs great. Only problem is that none of the gauges or ac or radio are working now. It all worked on both trucks before and I have checked all the grounds more than once. I can't seem to find what is causing the problem. The only thing I cut on the 02 harness was a brown wire going to my front blinkers. It was going to my car alarm in the 02 but i dont have an alarm in the 05. Please someone help.
