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?

Had the relay board out testing everything I could think should have continuity and everything checked out along with getting 12 volts in all the right locations. I put it all back together to test for voltage at the pump. When I turned the key it went on! I don’t know what the problem was. Moving forward for now.
