Unfortunately, it has become one of the most important aftermarket products for the Prius. Everyone desiring to know when the Internal Combustion Engine is actually running, wants one. (The MFD does not do this)
Goes for $129.00 postage paid and plugs into the OB2 Socket which is a receptacle just under the forward lip of the dashboard directly under the "power" button vertically, to the right of the steering wheel. If you are not bendable three ways can best be found with the use of a mirror. (it's a two inch plug)
ScanGuage is completely sold out and will not have any new units until early May but they are definately worth waiting for and the new ones may be made narrower. The production date can be secured by using "price" button.
