QuestionThanks Roland
For the input and output sensors on the 91 Lebaron, them are the ones on the font of the trans that we canged. I have looked for the distance sensor located at the top side of the transaxle extension, the car does not appear to have one. So I guess if you would be able to fax me a copy of the wiring diagrams for both the 91 & 92 year I would greatly appreciate the kind gesture. My fax # is 1-920-233-9766 and put ATT:Ray/Terry Thanks again for the input and help that you have already offered. Thanks again Ray Krueger

Question -
I have a 91 Lebaron convertable v6 GTC. I cannot get the speedometer to work. We have changed the transmission computer,body contol,smack computer,input &output sensors,and dash cluster. The only thing that does not work is the speedometer. I was woundering if you had a wiring schematic for this car? Heres the problem. I have a schematic for a 91&92 Lebaron but neither match to wiring for the car. So can you help us find the right schematic? I was told that half way through 91 they changed the wiring. But it does not match a 92 wiring schematic either. Thanks for any help you may offer. Raymond Krueger

Hi Raymond,
When you say you replaced the "input and output sensors" do you mean the ones on the front of the trans (e.g. the side that faces the front of the car)? If so then you may have not actually replaced the sensor that runs the speedo/odo function. At some point, I believe later than '92, the output sensor indeed became the source for the cluster speedo/odo. But earlier than that, there was for many years a "distance sensor" located on the top side of the transaxle extension housing (which is the box from which extends the two half shafts). It has a 2-wire connector and is held into the trans with a single bolt. The wires are light blue/black and white/orange and the white orange is routed directly to the cluster. So take a look behind the engine, down low at the trans axle extension housing and see if you find such a fitting with a 2-wire connector. The internal gear on the tip of the sensor is often damaged when a mechanic who is unaware pulls the right half shaft out of the housing without first removing the sensor. You can get a new gear for it from a dealer if that is your problem. If you want to check the function of it, just put an ohmmeter across the two output pins at the plug and rotate both the front wheels and note whether you get 8 pulses in the resistance reading for every full rotation of the wheels. Let me know if I can be of further help. I have both the '91 and '92 factory wiring diagrams for the LeBaron. (I own an '89 coupe myself).

AnswerHi Ray,
I will have to xerox copy the relevant pages and snail mail them to you but first I have a couple of questions:
Which diagrams do you already have (what is the source or the publisher of each?) Mine are the Chrysler shop diagrams for '91 and '92. You do have the original drive train in the car, correct? And which instrument cluster do you have: conventional/mechanical or electronic? And was the cluster type changed from one to the other at any point in the history of the vehicle? And are you aware that the is a different body computer depending upon which cluster you have? If you have a mechanical cluster do you have a white/orange wire coming to the cluster on the black plug, pin 5 and have you tried to determine whether it has a pulsating resistance signal on it when the front wheels are rotating? If you have the electronic cluster there is no such distance sensor wire, but rather a data bus wire pair (pins 7 and 8, violet/brown and white trace, respectively), correct? All these are relevant in figuring what is wrong that you can't get a speedo signal. By the way, does the odometer work at all?
Each year's diagrams in all are about 150 pages, show I need to select out the ones that are exactly relevant to your problem. Sorry I don't have a document scanner but it is no problem for me to xerox and mail them to you.
