Sorry about the hijacking of your post, ...... but I have not been wasting my time. I have been trying to workout exactly what one is supposed to do to get the later type flasher connected up. But I am having difficulty in rationalising the mod. As you know the old flasher relay only has a permanent and switched 12 volts, as the replacement one has, but the replacement one also has an earth wired into it..... pin 9.
The old one only gets its earth from the the various switches ( 3 off .... one for each direction and one for the hazard ) I can see where the front and rear lamp voltages come out of the relay, and the two 12 v going in .... There must be the hazard tell tail lamp output. Total pins used 8. ...... Now how does the earth fit into this ... pin 9 according to your pick .... BUT ..... there is no pin 7 indicated on your pic.
It is quite difficult to get a decent idea of what is going on ...... any chance of a scan rather than photos, so I can print out the info without trying to read my computer on its side ?
However, just going back to the relay repairs for a moment ..... I have had trouble with my Flasher relay and my Windscreen Wiper relay .... both being of the same type of function, and have successfully overhauled them. The problem with both were dry /cracked solder joints and dirty relay contacts ..... clearly the first port of call.
But it is nice to know if all else fails, a replacement is available ... if we can work out how to modify the wiring ..... I am still working on it.

Hi John...no problem...glad you are investigating.
I bought this as a spare..not actually needing it right now...but with 2 GTAs I suspect I will need to understand..and the instructions are not super clear...in language/readability or logic.
The way I interpret...based on they provide 3 large and 3 small terminals.(suggests that 2 terminals need to be popped out rather than cut)
....….........
Locate the flasher unit (137)
Modify wiring as shown. Take the wires from old flasher unit. Cut and connect to new female terminals as follows:
Pin 5 : three white/yellow wires (big)
Pin 4: three white/red wires (big)
Pin 3: two black/blue wires (small)
Pin 1: single violet wire (small)
Reuse the plugs for
Pin 6: single yellow wire (big) (+12v switched??)
Pin 8: single orange wire (big) (+12v ??)
Take an earth to pins 2 (big) and 9(small) .mentions connecting thick black wire from the indicator switch.

. Plated terminals shouldn't be abraded but if there's any corrosion you may not have a choice if you want to try and get it to work. Nothing lost if it doesn't. Cleaning up contacts on wiring connectors is Ok if corroded otherwise new connectors or a rewire is on the cards.
