2000+ CELICA GT INDIGLO GAUGE INSTALLATION INSTRUCTIONS
by An Nguyen ("bad" Andy")
Disclaimer: This is how I did mine. My set up does work, however, you are doing this at your own risk and I am not responsible for any mishaps that you might experience...
	Remove the 2 screws holding the gauge cluster cover at the arrow indicated
	Remove the three screws holding the gauge cluster at the arrow indicated
	Ease the gauge cluster out, and unplug the 2 plugs in the back of the gauge cluster. The gauge cluster is now free. Take it to your work bench.
	At the work bench, turn the cluster upside down and remove the indicated screws( green arrow). Gently push in the black plastic tab (pink arrow) on the side and slide the cluster hood off.
	Gently push in the clear plastic tab (green arrow) on the side and slide the cluster hood plastic cover off
	plastic hood cover separated from hood assembly
Use this tool or 2 spoons on on each side of the needle and gently pry off the needle from the gauge assembly
	needles are off the gauge assembly. Note that the two needles are different in size, the speedo needle is the longer one of the two.
	lay the new indiglo face on top of the gauge assembly, making sure the needle pin is at the center of the circle cutout of the indiglo gauge
	Gently put the hood back on, taking care to keep indiglo face centered with needle's pin. Push down firmly, and the black plastic tab should click and snap in place and hold the indiglo face on pretty good.
	Put back the screws on the back of the gauge cluster(green locations) and tighten.
	Bring the assembly and the clear plastic hood cover to the car. Plug back the two connector removed earlier. With the gauge hanging, turn on the ignition to the acc position. Wait for 20 seconds and the gauge cluster should calibrate itself. Speedo and tach setting now is calibrated to be at zero. Replace the needle , making sure it points to zero. Gently push the needle back on. Note: do not handle the needle by the arm. Hold it at the black plastic center while doing this. Turn off the ignition. Wait 3 minutes and turn it back to acc position. Needle should move as the gauge calibrate itself and then fall back to zero. If needle does not fall back to zero, carefully remove the needle and repeat this procedure again until needle show zero after calibration. After this put back the clear plastic hood cover. It will snap into place.
	Find a position you prefer and mount the switch and dimmer assembly. Drill an appropriate sized hole and mount the dimmer on. The switch will be a rectangular cut out, you will need a dremmel and lots of patient to cut out this rectangular shape. If you don't have a dremmel, a small coping saw work fine with a starter hole drilled. You may need to file the edge smooth afterward. This is my location...but you can put yours anywhere you choose.
	Connect the 2 wires from the gauge assembly with 2 long wires, a red and a black color one. I "borrow" some networking wires from work, a 18G twisted pair plenum wire that had a black and red colored wires. You could use speaker wires if you have. Anything 22 gauge or bigger would be fine. These 2 long wires is fed through the firewall at the rubber bushing. I removed the battery and used a coat hanger to punch a hole in the rubber bushing and fed the two wires through. The green line is how my wiring is done from the firewall to the parking light assembly.
	This is the parking light assembly
	Untwist and take out the parking light socket. Connect the red wire to the green wire of the parking light, using a butt wire tap or solder it in after cutting the green wire, restrip and connect back. Tape the wires up real good and put the light socket back.
	Connect the black wire to a good ground source. I used the old hole from the airbox for this. Turn the car ignition to acc position. turn on parking light to test the indiglo face. It should light up now. Check the switch and dimmer and make sure they function. It all should work. If it does not, check all your connection points (most likely notgrounded correctly).
	If all works fine, put back the cluster , attaching the three screws taken out earlier.
	Put back the cover trim piece, attaching two screws taken out earlier.
	Voila!!!!! nice ....Enjoy!!!!!!!!
