Autometer analog work good for me. You can scan all three in micro seconds no need to change the screen like scanguage. not the most expensive but not the cheapest either.
Temp gauge is the easiest to install. Go to your local parts place and get one of these....
Cheap at about $10.00 2 years ago. They come in different sizes this one was 33 mm but not 100% sure about the USDM one so just take your hose along or measure the ID. Find a good spot on your top hose and remove about 1 inch total for room to install the adapter cut and install the two new clamps, screw in your gauge sending unit, run a wire inside the cabin and hook up the power and lights wire and done. Install fresh coolant to top off and fire it up.
See how hot the Jazz/Fit runs very scary.
And finally nice night shot. You can change the caps with green or red or run with no caps and have white light.
