speedometer not working

[jason_bet]

Ok so I still have a lot of electrical things on my car not working.. are there any wires that go to the back half of the car for the speedometer?? i also cant get the fuel guage to work!! I thought i had all the wires for the guage connected.. but i guess not.. anyways good ideas on how to test and work out untill i find why the speedometer is not working?

^The speedometer is gear driven, there will be a black cable coming out of the firewall that will come down into the engine compartment, on the front differential, you will see a place where that connects to the transmission... you can unscrew that cable and unbolt the sensor (1-10mm bolt, IIRC)... check to make sure that sensor isn't all chewed up, if it is, replace it... if not, you'll have to replace the cable or the speedometer assembly...

I'm not for certain on the fuel gauge, but it is an electrical sensor, that you should be able to trace down the wires...

here's some more info on the speedo gear and its location. its basically directly above the differential in the transmission.

my speedo stopped working also, im gonna check the sensor tomorrow but what should i be looking for/how to tell if its gone bad? and if mine is indeed messed up, is it better to get a new(mb622090 $69.62 from rockville) or used one?

[dhrubio]

well i went in there to find out why my speedo isnt working..and look at this

looks like the speedo cable got fried from the sensor? not sure what to do or what i need (speedo sensor, cable, gear?)

All TT's and 94+ NA have speed sensros.

is there any way i can just put the 3 wires (yellow, black, black w/ white stripe) back into the harness with red edges(speed sensor)?

[Linebckr49]

dhrubio---> so somehow the wires to your speed sensor got cut or torn? i would definitely repair the broken wires. not sure how much wire is left on the sensor side, but i would repair it first before buying a new sensor.

From the pic it actually looks to me like the plug in pulled apart. It may be fixable

[dhrubio]

yea theres actually no wires coming out of the sensor at all! thats why im not sure what to do...ill go take a pic right now

connector


heres the bottom of the connector



and heres my problem: the top; you can see the three holes where the three wires should be


a couple posts up i put a picture of the whole area and you can see the 3 wires just hanging around
