%.0 wiring harness
 

Hello Im in the Begining stages of doing a 5.0 swap into a 4cyl car and its my first ever.

I was just wondering if all I will need Is the harness from the front bumper to the firewall or do I need everything Behind the dash as well I have a complete 5.0 car so Im stripping everything form the engine bay. As well as the computer and all that other stuff.
