I in the process of replacing the rear Body harness in the car. Using two harness from American Autowire.When I hooked the trunk lamp noticed it was continually on. I checked the assembly and service manual, both show a 20B lead. The connector in my harness is a 20 orange..Also has a plug in the harness in the trunk where the rear trunk harness plugs in. The other thing is none of the manuals show a replacement number for the trunk lamp. I did check that when the trunk is closed the light goes off. Is it a special lamp and does the SS for 63 use a different configuration? Anyone else run into this?
