Well I got a short in my tai lights and my led license plate light. Now my car won't start it just cranks. Fuel pump doesn't make a noise, I bought a body harness from a mustang that was parting out and spliced it into my old one but my car still does the same thing, just cranks. Tai lights won't function properly. All of the wires in the trunk on the harness matched up except 5 of them. There are 2 green/orange ones and 3 brown ones. Maybe I didn't hook those up right idk..... What else should I check? I know mustangs don't have a fuel relay I checked the fuel pump fuse and it is good. Im pretty novice on electrical problems. Pease help me out!!!
