Greetings,

I installed a VDO 310-105 vision black gauge in my D90 and the sending unit I used was a 323-483 as it was the only one in stock that would fit. This sender has a floating ground. I've connected the sender to the gauge and the other terminal to the block. It appears the gauge is trying to deflect in the negative direction. I've confirmed I've got + and - connected correctly to the gauge. Any thoughts? Can I change the + and - on the gauge without risking anything?

Thanks!
