Wedge TR7 Hazard Light Switch

Im not extremely electrically savy but i thought my schematic reading was somewhat upto par but now im doubting myself. im trying to wire in new switches and make a new switchboard in my TR7 but the hazard light switch has got me baffled. Is there a special switch needed rather than a two prong toggler? no matter how i wire it i either get the hazards working fine, but zero blinkers or hazards working fine but when i switch the blinker to the left or right , they both blink! i keep wiring it to the way ( i understand ) the diagram shows but im still lost. theres a green wire that gets 12v power, key in or not. the diagram shows that going to the side of the switch which would recieve power when the hazards are on but that just sets all four markers on continuosly, no blinking. . anyway if anyone may know where i ran off course maybe you can nudge me back on track,

I don't have a TR7 diagram handy; is it reasonably similar to the diagram below?

The stock hazard switch is almost always a special, I'm not sure exactly why. In addition, the green wire should only be hot when the key is on. The hazard side of the circuit should be fed from a purple wire, which is hot all the time (unless you pull the fuse), and also through the hazard flasher.

There is a way to wire it using only a DPDT for the hazards, but it may require some other changes.
