gear position indicator/speedo odometer

i have a 2005 rancher 350FM 4×4 manual shift. I would like to install an aftermarket gear position indicator and maybe one which has an odometer or even speedometer combo deal. I was wondering if there was a simple plug and play deal. one which could be plugged up to existing wires or one which can be mounted near the gear shifter that would pick up the motion of the shift lever. I have seen some for around $9.00 that is just the shift position indicator. does anyone know of a compatible gear position indicator or speedometer which includes gear pos info which would work on my particular atv by pluging up to existing factory wire harness or aftermarket deal that I can mount myself like a universal model. any info is appreciated. including website and model so I can search it online and find it. thanks so much.
