Larry, thank you for your input.
What I am using is the MGB diagram, using the stock SW which has 6 leads.
This is what I am using, a large MGB wiring diagram cover in plastic so that I can mark and erase as needed.
Easier for me to follow the wires.
The colors are # 1 Green/white---- To the turn signal sw
#2 Green/red ---to turn signal left front, not the turn signal sw
#3 light green/brown------to the flasher
#4 light green/purple------hazard light on panel
#5 non-existence same as # 6
#7 green-------to turn sw
# 8 green------to power 12v
Confuse about #2 wire shows going directly to the turn lamp.
#7 and #8 both green wires.
# 154 in the diagram is the flasher and # 67 is a fuse.
It is our attitude that will determine the outcome

Bill,
Here is a cutout of Dan's schematic. Maybe this will clear things up.
When the hazard switch is on:
When the hazard switch is off:

When the hazard switch is on:
- Pin 5, which supplies power to the turn signal flasher, is disconnected
- Pin 4 is directed to the hazard lamp indicator
- Pin 3 is connected to pins 1 & 2, which direct the pulses of the hazard flasher to the turn signal lamps.
When the hazard switch is off:
- Pins 1, 2, 3, & 4 are disconnected.
- Pins 5 & 6 are connected and supply power to the turn signal flasher.
