Sorry for this probably-very-stupid question, but what is an EVIC. I found OTIS in my owners manual.
And if an EVIC is what I think it is, how can it (or an OTIS) be installed and functional in a car that never had one, just by wiring down to the fuse block. Doesn't it have to tie into some system to get speed, and fuel information?
If there's an easy hookup, I'd like to consider it for my newly acquired 2000 Intrepid R/T.
Thanx,
Bill

I did it following Intrepidatious' how-to, and its been working great for several years now. Picked up the OTIS at a junkyard ($50). At the same time they let me cut out the relevant fuse box connector (I left a few inches of the harness on the connector so I could splice my own section of cable later). Not sure how hard it would be to pull the entire original harness out through the roof and A-pillar, but I was under the gun at the junk yard to get what I wanted quick. For me the most frustrating part of the process might simply have been blindly finding the A-pillar opening (for the cable) from the OTIS opening. BTW: one wire communicates all the temperature, fuel consumption & mileage data because its a serial data bus.

Basically, go to a junkyard and find a car with the OTIS Or EVIC(EVIC has INSTANT MPG or tire pressure where OTIS does not, thats the difference)

After finding a car, take the headliner down and take the entire wiring harness off (its glued down so you gotta give it a good tug)

After you get the harness (remember to undo the wiring, not cut...unless you like extra work splicing later) grab the evic and pay for it and get home.

Get home, take your a-pillar down and slowly remove your harness, there is a better walk through in several sections of the site, i just recently did mine well worth it :)

OK, now I'm starting to understand, especially finding out that the data is transmitted to the unit via serial bus. However, a couple of questions remain: does the serial bus plug into the fuse block also? and is all the hardware already on the car for the various information that EVIC and/or OTIS displays?
Mileage/fuel consumption/speed, etc, I'm guessing comes thru the bus from the car's computer. But what about outside temp? compass sensor (or is it in the EVIC/OTIS?)? etc. I don't know much about factory wiring, but I'm surprised that everything's there already except for the display.
(I'm a DIYer, but I do learn as I go, not having any prior experience with factory wiring, installations, etc.)

FREEZINGBELOW, do you still have the OTIS and willing to part with it for free to a newbie?
What color is it, or are they all the same?
Do you have the wiring harness as well?
thanx,
Bill

Everything is there except the OTIS and the associated harness. On a non-OTIS car the harness running from the fuse box to the map lamps only provides power for the lamps (i.e. does NOT have the extra wire for the serial data line). Temperature is in the serial data stream just like mileage etc. It comes from the BCM through the connector in the fuse box. On ALL Intrepids the BCM gets the raw temperature signal from a sensor inside the front bumper (I guess used as an input signal for stuff like fuel injection operation and winter AC disable). The compass sensor is inside the OTIS itself. Once you're done the install you've got to put it in calibrate mode and drive three tight circles in an empty parking lot. Also you program in a variance specific to your location within North America (complete instructions are in FSM ...downloadable from this site). Another great feature is the universal transmitter function (garage door opener etc). Good luck!

ANDREWW, thank you very much for this reply. That really cleared things up.
So, actually all that is needed is to enlarge the hole in the headliner, and run an ignition-controlled power wire, and the serial data wire up (un-controlled power, and ground are already up there). I would think I can do this with only removing the A-post trim and not removing the headliner, correct.......Gee, that's extremely simple.
Again, thanx.
