I would like to hook up a digital temp gauge but I'm not sure where the (I guess it would be) the sending unit would go. Would I splice into the factory sending unit? I'm sure its been done and would like a few tips. I'm ordering a basic/generic unit off ebay. I don't really like the 4bar gauge honda has and being a trail rider its not uncommon for a radiator to get clogged with dust and mud. Thanks in advance!
