Blitz R-Vit

If you are an owner of Isis, you will notice that the car didn't come with a water temperature gauge, although this is a common practice on all new japanese car but I still prefer to know what's the water temperate while I am driving.
Why ? Because I had a bad experience with my other car which resulted the engine overheated and stranded me somewhere in the highway.
Lucky for me, I manage to get myself a Blitz R-Vit from my other car and installed it into my Isis. This devices comes with 3 set of wiring, one from the OBD port, the other one from the cigar lighter plug and last if for the device itself.
I prefer a clean interior and hide all the wiring away from view hence I cut a hole from the button cover and pull the wiring inside the dashboard. The display itself was glue on using double sided tape. So far the double sided tape works even on hot weather.

Next is the power point, I route the wiring into the cup holder area and last is the OBD port wiring that I hide all behind the dashboard. A cable tie secure everything behind. Toyota Isis OBD port are located at the bottom of the dashboard (driver side) next to the latch to open the bonnet.

R-Vit is capable to display up to 6 parameter of your choice in the same time, but I prefer to show on 3 parameter as the display is rather small and bigger font does help during viewing.
The parameter that I choose for Isis is "Gear", "Water Temp" & "ATF Temp". It is good to know your ATF oil temperature to help you guard and save your gearbox from going bad. High ATF temperature will shorten the lifespan of your gearbox. Repair of gearbox is costly and it is not easy too.
