civic vx 02 sensor UPDATE and lean burn monitor ?

So...
I finally got my new o2 sensor for my new vx. I read a few reviews from a seemingly sharp guy over on gassavers and he said that he used the $77 one from ebay and that it worked great.
1992-2000 Honda Civic Upstream O2 Oxygen Sensor: sg335-REA1134-36531-P07-003-36531-P2M-A01 Auto Parts Direct To You | AutoPartsDirectToYou.com

I decided to order it and it arrived today. I popped it into my vx and went for a drive...WOW it felt great. So I went back home, got my voltmeter and hooked it up to monitor the lean burn, and went for a drive. Sure enough the lean burn works great with this o2 sensor. I can feel it engage, and see the voltage go to the positive side when it engages (around +.52 at 60mph). It is really nice having the meter hooked up so I can see that I am in lean burn (although nowhere in my drive around did I ever kick it out unless I really tried).

Now what I would like to know is does anyone have a step by step to making a light-up lean burn monitor (like a green light that turns on)? Please be very thorough in your explanation b/c I am an electronics dummy.

Just thought I would let everyone know about the cheap o2 sensor and pick your brains a little more.

I am ready to start tracking mileage and see what this thing can do!!!
