I have been following the directions in other posts to wire my car for carbs with a low pressure pump under the tank. In front I have a black/red wire and brown for ground which is expected. My number 13 pin on the 14 pin connector is green rather than black with red. I can't find a diagram of a '75 relay board and it's not in my manual. The previous owner had blue a jumper wire connected as shown in the photo. Is this arrangement right for this year when running carbs?

The blue jumper wire activates the fuel pump without the efi if I remember correctly.
