Just bought an 87 Allante and fixing the little things. From looking at the listings I will be doing a lot of that. The other night all of the lights in the left tail light and center stop light went out at the same time. The lamps are OK. I bought a SIM online and after looking at that I still don't know where the problem is at. On some of the electrical diagrams, it lists a rear fuse panel. Where is that? This is the most complicated electrical system I have seen. Help. Thanks.

 

I found the problem. It was a loose connection on the wire bundle and/or relays behind the right side panel in front of the right tail light. I wiggled them and they all work now.
