Please be aware the HL 6.1S, 6.0S, and 6.0 motherboards have different wiring from the Taigen tanks. It will not work stock without a rewire to get it working properly. HL includes in the instructions a diagram on what item does what if you wish to retrofit this item into a new tank. It can work in a TG tank, but you will need to wire it a bit differently to match the HL scheme.
