I'm using a bunch of different sources to try to build a fairly complete single wiring diagram for my 1963 Series 62 convertible. I've got a couple of questions:

1. Does anyone know what the circuit circled in red on the attached image does? Near the bottom of the marked area it seems to have a switch between the white wire and black grounded wire, but I have not been able to find this circuit leg in any other diagrams I've looked at.

2. If the car has AC, does the typical AC wring replace the non-AC blow/heater wiring? I assume cars with AC have only one blower motor. Can anyone confirm?

Once I get done, I'll share the work with this group. I know about (and have) some of the other color diagrams. I am building my own not just to get me the picture I want, but also because it helps me better understand how the car is wired. Fortunately, the wiring in my car seems to be in decent shape.

It appears to be the door activated switch circuit for courtesy lamps.

Thanks for the replies.

Dan, that was what I thought at first too, but the diagram has front and rear door switches located elsewhere. However, your idea leads me to a question. Is there a switch inside the car to turn on the courtesy lights (perhaps on a ceiling light on a hardtop car)?. I have a convertible, so I suspect such a switch might exist, but not on a convertible.

Edelbrock Carb Block off Plates

Posted by Chase on March 12, 2025 at 2:05pm 14 Comments

Hey guys,

I have installed the same Edelbrock carb and have done everything the same as Jason’s carb and intake project. In the spring and summer months the car starts, runs and idles great! In the fall and winter months on a cold start, the car starts awful and wants to die until it warms up. I have to keep my foot on the throttle until it warms up or it will idle just terrible and try to die. Once it’s warm, it runs fantastic! Whats going on here? I was thinking of removing the…

Loud air moving sound within carb with cleaner removed

Posted by Dave Fehrle on March 23, 2024 at 3:23pm 8 Comments

While checking my Carter carb with engine running, I took the air cleaner off and there was a very loud hissing sound of air. I placed a piece of paper over the carb and it didn’t move up or down, is this normal?
