Bmw e34 side gauges installed

Dragon Gauges from eBay, better are digital ones. Holder also from eBay, but modified with hot air gun. Oil pressure adapter from eBay M14x1.5 - 1/8" - M14x1.5. Oil temp adapter made myself M12x1 - M10, bronze 1/8" sensor fits in M10. AFR gauge a bit strange, wide range, but voltage 0-1V, so to use with wideband signal (0-5V) i used to make simple voltage divider with resistors.
