I recently bought a 1986 Spider Veloce that will surely require parts and access to technical information. Any tips on reliable sources for parts would be appreciated. I just replaced the the license plate light bar and created more trouble. All bulbs in the light bar and center brake light are good. there is good ground and power at the contact plate AND at the pins located on the corner of the trunk lid and the short harness has been replaced. the lights with light with external power to the trunk lid but not with the trunk closed.
