MPG display?

[evildre]

The Gen 2 Solara has it, the '02 Camry has it, and my '88 Sedan deVille had it. How do I get it in my Gen 1.5?

buy a thingy called "Scan Guage" It plugs into your ODB2 plug and tell you other useful info, including the mpg you wanted

That does look pretty spiffy ... is there any way to get that to display in the clock? I'm asuming there's something like a Scan Gauge that sits in the Gen 2's dash, displaying the relevant information on the clock ...

Where would I get a hold of wiring diagrams for a 2002 Camry and a 2002 Solara? I'm sure the ECUs are similar enough and I could find all I need in the dashboard of a 2002 Camry ... there's a salvage yard down the street from here I could check out.
