R34 triple gauges not working

Hi.  

So a few days ago I had to replace my cars heater core (please do consider taking your car to the workshop instead if yours starts leaking!! Wouldn't want my worst enemy to go through this). 

Anyway,  all good and started putting it all back together.  As  I had to pull out the dash,  I unplugged everything attached to it.  Now,  after I put it all back,  the middle gauges are not working. The plug is in there nicely, so I'm wondering if there is anything else there I might've missed? Before I start pulling it all apart again,  maybe there is a simple fix that I missed. Before that the middle gauges light was flickering from time to time,  caused by a loose bulb.  Only thing I did was fit the bulb back in properly and that's it. 

The reverse camera is also not working now but that's aftermarket and I'm sure it's just a loose plug. 

And while I'm here asking questions,  maybe someone could tell me the color of the wire I should tap the subwoofers remote to? 

Thanks.
