** Important notice: The EL glow gauge is emitted by AC voltage, the inverter will transform the 12VDC to 50~75 VAC. After connecting to power, don"'"t touch bare terminals or solder points over the output side, will cause uncomfortabel electric shock. The natural color of EL (electro-luminescent ) is between blue and green, we design the inverter with high and low frequencies, the high frequency will emit the EL to glow blue color, and the low frequency will emit EL to glow green color. A switch on the dimmer allows you to change frequency /color. However a disadvantage of the design for blue glowing will cause high frequency noise. There is no solution to remove the noise but can minimize the noise by decreasing the brightness or switching to green light section. If the glow gauge is white light, the high frequency will emit cold white, and low frequency emits warmer white light. Before purchasing this item, please consider this fact. Fitment: for 3 Series (E46) 1998~2004, Diesel (6000 rpm) Product information: Package inlcudes 1 set EL glow gauge and 1 piece inverter Color: gray panel white light or white panel blue light (select one when placing order) . Product condition: Brand New. This gauge is with speedometer in KMH (Km/hr) Brightness adjustable thru the controller on the inverter. Not necessary to remove needles for installation. Anti-glare andscratch resistance surface. Product Pictures: Installation Guide: Disconnect the negative terminal on the battery. Remove screws that hold the bezel and cluster. Disconnect the wire plugs to the cluster. Remove the clear cover that protects the needles and the black housing around the gauge. If there are screws that hold the faceplate remove them. Gently slide the gauge face over the needle.DO NOT REMOVE NEEDLES Careful needles are fragile Locate a spot to run wire in the cluster. Screw in the screws to the faceplate, if removed. Install backthe clear protection cover. Plug the connectors of faceplates to inverter. Locate the controller to desire place.
