The T4 connector on the regulator/relay panel is not marked to indicate which connector is which. Can someone confirm if I've numbered these correctly. I think they are because the yellow wire is supposed to go to T4-2 which is one of the two rear connections.
According to the electrical schematic T4-2 and T4-4 are tied together and go to ignition switch. On my car, there is a black wire (see photo) which leads to a switch under the dash which is connected to the fuel pump. The engine was carb'ed which I have removed and reinstalled the fuel injection. According the schematic T4-1 and T4-3 go a "power supply relay" which I assume is how the fuel pump is currently operated. I'm going to set the fuel pump circuit up how it's supposed to be. Any advice?  |

Which FI system are you installing? They are not wired the same. "Yellow wire" is L-jet which does not use the relays on the board. The pump is powered by the dual relay. Look at the AFC/MPC diagrams here. T4 pinout in the pic below.
