I was thinking of getting it for the Jetta, then I thought, why not the Celica >> ?
I searched for comparable units and found cheap ones that look like crap. This might be a cool option to have.

Wiring would be easy/universial for any car. Just where to put it on the dash is the big question...

any suggestions/comments ?

An Internal/external temp sensor is cool, but not need for the celica. I admite it is cool looking, but since my celica is limited on space I think I will pass. I you are thinking about mounting it I would say that the cigarette lighter and ash tray space might be your best bet to place that.

the spot next to the lighter I think is my best option right now. I'm not sure. I might just take out the lighter and put it there. I am probably gonna get one for the Jetta and see where it would look best in the Celica.

anyone other ideas ?

Looks great.

if it had a built in clock, i would get it and set it up were stock goes.

ur jetta doesnt have teh temp sensor on it already. like in the dash cause my friends gti has it but maybe its and option from the dealer.

that in/out guage comes with its own sensors sev

newer Mk4s (02+ I think) have a in/out temp guage built into the guage cluster stock. My Jetta is a 99.
