Here's the pinout for EP26 and OEM flasher relays. I've marked those pins on your picture. Standard flasher relays have Power (49), Ground (31) and output (49a)
There is no connection to ground and there's a wire connected to C2 which likely is doing nothing. If you want to see if this flasher relay will function, follow the wires from this connector to the flasher relay and correct the C2 and 31 wires.   |

Wow
Thanks very much for the help Spoke and Mgphoto, the diagrams help immensely. Spoke, I ordered your relay and am waiting for confirmation/payment info. Are you suggesting I short C2 and 31 to test relay? If you want to see if this flasher relay will function, follow the wires from this connector to the flasher relay and correct the C2 and 31 wires Also no ground connection for the relay? This schematic shows Brown to Ground. Attached image(s)

This schematic shows Brown to Ground. Mike, did you order from me on 5/9? That order from a Mike was for the later '74-'76 mod. You have an early tach with separate L and R indicators, correct? For your current setup, you do not need to ground C2 just to see if you have flashing. Check the pins on the existing flasher relay and put 49 (power), 49a (output), and 31 (ground). This would be just to make sure the wiring is ok. |
