Anyone add more leds to Defi Control unit?

[NewShockerGuy]

This is kinda car related but it's leds... so figured it would work here:

I'm not a dummie when it comes to soldering or things like that... this however is throwing me for a loop.



I have a defi control unit II.. they only put in 3 leds and so the light spread isn't great... there are two more slots for leds.



I have a SPARE board so I de-soldered the smd leds off and now have 3 extra sitting here... I tested with a normal LED on the spot where it would normally be soldered on and it's not lighting up... reversed polarity and still nothing.. .which leads me to believe that there has to be a bridge made somewhere...



I have the following pics.



LED 2, LED3, LED6 have the smd leds there and those work... All I want to do is add LED4 and LED5...



I know this might be asking a lot but by looking at this pic anyone know what to bridge?

Back of unit:

Thanks,.

Can you find me an actual schematic for the unit?

It looks to me that they have paids of LEDs are in series. Im not sure where a bridge would be needed, ill keep looking.
