It would connect to pin one and pin five of the closest 5 pin tube to the lamp. The lamp socket can not be grounded to the chassis. Must have two connections. Neither connected to it's mounting bracket.

Pins 1 and 5 are closer together than the others. The 27 and 24A share the same base configuration.
