Around $200 is what I gave for mine. You have to hard wire one 12v switch power wire and the other just plugs to the diagnostic port.

 

I cant watch oil and trans at the same time with that.

 

you can watch 2 parameters at a time with the interceptor scanguage. You can actually set it up to record those 2 parameters. It will start recording when it see's >50% throttle. This is handy for me at the track to see IAT's. It is also handy if you want to see your mph if your guage only goes to 100. The advantages of it are almost endless.

 

Actually you can. It displays more than one output function at a time.
The 12v power can easily be added with an add a circuit from your local parts house.

Did you know you can view 2 different parameters at one time?

I am not sure if your engine has an oil temp sensor on it though. If it doesn't you won't be able to see it on the scanguage of course, even if you add one. The scanguage sees basically ever sensor that inputs into your computer.
Also, you can view more than one thing at the same time with it.
