I have carburetors, no heater, and an aftermarket fuel pump on its own relay from the battery.
What do I need to do, to get rid of the relay board all together, and to simplify the wiring? |

The "govenor" is the voltage regulator and 90 is the board itself. If you don't need the FI relays the board is easy to eliminate. Many wires are just spliced together including the oil light, backup lights, starter solenoid, tach signal and coil power. Here's a list of what goes where.
T14 Connector 1 Starter solenoid power in from igntion switch 2 From voltage regulator to alternator warning light 3 Power in for backup lights 4 Power out to backup lights 5 Out to oil pressure warning light 6 Not used 7 Tach signal out to tach 8 Power in from ignition switch for coil 9 Ground signal from heater fan switch 10 Chassis ground for relays on board 11 Power out to heater fan 12 Battery power in to fuel injection power supply relay 13 Power out to fuel pump 14 Battery power in to fuel pump, heater fan and rear window relays T12 Connector 1 Signal from oil pressure switch 2 Power out to backup light switch 3 Not used 4 Power back from backup light switch 5 Tach signal in from coil 6 Power out to starter solenoid 7 Power out to ignition coil 8 Not used 9 Not used 10 Heater fan jumper wire to T12/11 11 see above/fan can also be powered from this terminal instead of T14/11 12 Power out from fuel pump relay to aux air regulator |
