Lebaron Traveler Computer Installation
Installing a traveler computer from a '90+ Lebaron into a '91+ Daytona is easy as pie. The first step is probably the most difficult. It is finding a trip computer. Daytona's never came with these computers or anything similar after the 89 model year, but lebarons did. The pre-90 Lebarons and Daytona's are easy to find and a good percentage of them have trip computers. But, they won't fit perfectly in the newer dash of the '90+ Lebaron/ and Daytona's. You can, however, fabricate your own mounting techniques. I'm not sure if the wiring is the same in them either. Make it easy and locate one from a '90+ lebaron. And if it comes from a junk yard, hopefully it works. Mine was in a '90 lebaron convertible, top down, sitting in the yard for a year. Works great though.
Lets get on with the wiring. If you find a computer out of junk yard, remember to also get the wire connector. Just clip the wires so you have plenty of extra wire to solder new ones to. You will not find this connector in Daytona's. All Lebaron coupes and convertibles already have the wiring harness behind the dash, so you just plug the computer into it, mount the computer, and you're set to go.
The connector looks something like this: Note that the pin numbers are labeled
along with the color of the wires.
Pin 1 goes to an ignition power source (power when ignition key is on). I wired this to the defroster switch power source. Use a voltmeter to determine which wire behind the defroster switch is the ignition power.
Pin 2 is ground. This can go to any metal surface on the car.
Pin 3 is for the illumination. Again, the wires behind defroster switch is an excellent source of power. And, again, use a voltmeter to make sure you use the right wire.
Pin 4 is not used for anything.
Pin 5 will not be used either.
Pin 6 is the positive data bus. In a nutshell, the data bus is the source of the information it needs to compute its functions. The traveler computer recognizes electrical impulses from this wire, and turns it into data you and me can read on the display. This wire is a little tricky to hook up. It goes to the body computer of the car, which is behind the front passenger kick panel (behind the panel to the right of where the front passenger's feet would be).
On the body computer, there are 2 large connectors on it.. a black one and a grey one. We will only deal with the BLACK connector. If you look closely on the connector, you will see tiny numbers on it where the wire enters the connector. You want to remove some insulation from the wire labeled #7, and connect Pin 3 from the traveler computer to wire #7 on the body computer. I do not recommend clipping this wire... just remove some insulation off of it, so you can solder a wire to it.
Pin 7 is the negative data bus. It also goes to the black connector on the body computer. This one goes to wire #20. Perform the same procedure as above to connect this wire.
When you're done, when the key is turned to the run position, the display should come to life. If nothing happens, wait awhile because as long as pin 1 and 2 are properly hooked up, you should get a message on the display which says "F1-1" after about 10 seconds or so. This means the computer works, but the data bus probably isn't hooked up right. Before installing the computer, I recommend to give power to pin 1 (positive) and pin 2 (negative) and see if anything pops up on the display. It takes awhile for that F1-1 error message to show up, so give it about 10 seconds or so. If nothing shows up, I would assume the computer is dead, toast, fucked, you get the idea.
