Relay Board, How do I get rid of it? Options

[chris914]

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?

[chris914]

Here is the pin out to get rid of the relay board:

T14 Connector => T12 Connector

Starter Solenoid:
1 - Yellow => 6

Voltage Regulator Alternator Relay:
D+ => Red
D- => Brown
DF => Green -> 2 – Blue

Backup Lights:
3 - Grey/Brown => 2
4 - Grey/Brown => 4

Oil Pressure Warning Light
5 - Green/Red => 1

Tachometer Signal:
7 – Black/purple => 5

Ignition Coil:
8 Black/Red => 7

Ignore pins 6,9,10,11,12,13, and 14 if you don’t EFI or a Heater

I’m going to get a new multi-pin-connector and cut off the old ones.

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
