Help me brighten up my cluster lights (pics within)

So, I've just been contortioning myself in the interior of my car to get at a few bulbs and things. I'm looking to brighten up my guage cluster lighting a bit (not being able to see my temp guage at night has caused me problems twice now) I plan to go about this by installing new (and brighter) bulbs in the cluster, and by bypassing my rheostat dimmer switch. Now, the questions and pics:

First, the rheostat. I've heard that there are 2 ways of bypassing this. You can either cut all the terminals off the wires and twist-nut them together, or, if you have a car with an extra prong on the back of the rheostat, you simply move a wire off of it's normal place and to that extra prong. As we can see in this picture, I have an extra prong:

Am I moving the red/white and gray wires, or the brown ones?

And now, the back of the cluster:

The upper hole I have marked is where the bulb I have came out. I noticed that theres another identical hole at the bottom of the cluster. Is there supposed to be a second bulb here, or was this meant for somethign else? The bulb I have fit perfectly in it, anyway. I couldn't find any other sockets on the cluster..are those the only 2?

And yes, I did just about kill my (large) self trying to get those pics
help is appreciated!

I just realized that I'm actually messing with idiot light bulbs in my second picture :\ I'm an idiot, so i guess thats fitting

Anyway, my car is a 86 245 with a K9800 dash. Can I assume that the lights that light up when you turn the headlights on are actually inside the cluster, or what? Mine only light up the clock, really. Everything from the speedometer to the gas guage is usually dark at night
Is it supposed to be like this or is there a light on both sides? I'd like to use the dimmer trick to get some more light thrown.

I think the upper one I have pictured is the turn signal socket :| I didn't see any other bulbs near the top.

Cluster lights replaced. Gear indicator light replaced. Taillights re-grounded. Dimmer rheostat bypassed. Everything seems to be working.

Now I've just got to install my new radiator and stuff when it arrives tommorrow, button everything up, and I should be good to go.
