@elvis 840 bhaijaan u have 05 big grey connectors, which is good as i only have 02 in my baleno.
So take out your speedometer of rpm,km/hr,fuel gauge and temp gauge, after unscrewing the screw on the backside, but make sure you donot ruin the golden ring plates which are beneath screws.
Clean the cluster with soft cloth and also the crystal type thing which is backside of the meter, i donot recommend you to takeout needle from meter because if u took it out u need to put back it from the professional person.
Buy an led strip just like i bought it for myself, in this led box u will get a lot of connectors which are used in cluster meter, inside car dome etc. So use that cluster meter adaptor and connect it with the led one, but make sure before pasting it with double tape u need to find a perfect place so that the led dont touch any of the part of gauges. ok, maybe u need to sand or take some plastic part from the cluster.
And for the rest black connectors which is i think 09, use 5mm led bulb put a resistor of 470ohms and connect it with + terminal which is long one and solder it with the connector and after right connection by checking it with the 12vdc power supply glue it with silicon glue. U need to solder it because the proper plastic bulb adaptor are not available for such small connectors.
after all that fitting just put it back and see the results and if u want to change the colour of led light use red tinting paper for red light, as for other colours as well and make sure you will screw them gently.
