Don I dont see that well and i am looking for the power that supplies the 3 prong turn light flash unit I dont have power there
Expert:  Don 'Mo Lurch' replied 7 months ago.

sorry...........I answered your original question for a Wiring Diagram
1949 Chevrolet 3800 did NOT come from Factory with Turn Signal Switch or Turn Signals
1954 was the first year for Turn Signals
Your 1949 Chevrolet 3800 must have "Aftermarket" Turn Signals, so the wiring for the "Turn Signals" will NOT be in the Factory Wiring Diagram
For the "Aftermarket" Turn Signal Switch, you will need to trace the wiring down to see where the Main Voltage + wire comes in.
Typically the Key Switch, but it depends on who installed it
IF you can post the Manufacturer of the Turn Signal Switch I can see what I can find

I need the 3 plug in piece power source
Customer: replied 7 months ago.
It's for the turn signals
Expert:  Don 'Mo Lurch' replied 7 months ago.

I understand.........

This is NOT Factory..........It is Aftermarket
The Turn Signal Lever mount should have a Brand Name or Number on it
Can you post a picture of the Turn Signal Lever & the Plug you have?
