Correct type Power Supply?

[wrench]

Can I use this Power Supply with the DSP Conversion? The Contacts have no labels or markings e.g TH,TL...

[Tech_Marco]

Look like OK.
The terminals should be arranged like this:

TH TL WP GND IN +5V

If you tide TL, WP to the ground and +5V to the IN, it should fire in 100%

Tie like this?

[Tech_Marco]

Yes. But I'll add a push button switch between "TL" and the "GND". That way, you can manual control it On or Off by the button switch

Like this? And what will this button control?

[Tech_Marco]

No, that is no difference at all.
Break the connection on #2,#3 (counting from Left to Right) then add a push button

In my first post on this thread I posted three pictures of my Power Supply.
The second picture show a big RED cable that goes to the tube.
The third picture shows a smaller RED cable that I think went to the old analogue gauge. Where does this wire go to now?
