Tachometer issues...

Tachometer issues...
Im sure this has been covered 100 times before but I believe my situation is a tad bit different and I could use your guys' help.
I hooked up my tach much like the how to article of hooking up a tachometer says too. However I am receiving no signal. I cut into the tan and yellow stripe wire on the back of the gauge cluster as per instructions..
I am also wondering what wire I plug into to get the tach to light up.. I read that I splice into the illumination wire. So which one is it and how do I exactly splice into it?
So what am I missing or what have I done wrong?
I was able to start the engine, lights all seem to work so I know I didn't cut off something fatal. I didn't get to see if the speedometer was affected but I doubt it is... much less any gauge..
Any suggestions would be much appreciated.

The tan/yellow is the correct wire for the tach signal and any good chassis ground under the dash should be OK.
I wouldn't wire the tach positive to the lighter because the lighter is hot even when the engine is off. A better choice would be a wire that is hot in Start and Run. A possibility could be any one of the three red/yellow wires at the back of the instrument cluster.
The dimmable instrument lights are on a light blue/red wire. You can tap into it at a number of places including the radio harness, HVAC control panel or cluster.

Okay so this raises a few questions for me.
1. If I tap into the light blue/red wire for illumination, how do I make sure I still will have my gauges light up... Can I just use a cap and put the tach illumination wire, and the two cut ends of the gauge wire and put them all in the cap?
2. Can I use the cigarette lighter ground as my ground? Its grounded to itself and looks like a decent ground?

Thanks. That helps.
Heres another thing.. I used a volt meter on the tan/yellow wire cable that should be for the tach, however it is not changing voltage at all even when the engine is on/revved...
Im not really sure whats going on with the tach signal wire? Should I look to another color wire behind the cluster or perhaps in the engine area..?
