Does anyone know where the Joint Connector No. 3 is located on the truck? It has a few wires going to it including 4wd, horn and a few others. I am trying to trace a wiring problem with my 4wd and need to be able to follow the wire to this connection.

Gambling guess would be within the PDC (Power distribution center) under the hood.

Ill have to check but I think joint connector 3 is firewall, drivers side, high. Sent from my SPH-L710 using Tapatalk 2

1999 service manual lists it as 'near powertrain control module' , don't know if same for your year.

Im still having problems locating this connection does anyone happen to have pictures?

I did some more digging yesterday trying to find the mysterious joint connector number 3...maybe i have the wrong name for the connection i am looking for but i traced the wire (from the 4wd switch) as far as i could follow it (which wasn't very far) and it goes up toward the right wheel well. The connection im trying to find is in the diagram in the following link... http://articles.mopar1973man.com/images/2ndgen24v/antilock-brake-system/4w-abs-2.jpg Im not sure if this is a plastic connector or if it is just a splice or what but it looks to have at least 7 wires to it from the diagram. Any ideas? Sam

did you see my post above? 8 pin connector using 7 of the slots?

did you see my post above? 8 pin connector using 7 of the slots?

yea i did see that but the only issue is, is that i traced the wires to the drivers side not passenger side so that info must not be correct for my truck.

Oh ok. Sent from my SPH-L710 using Tapatalk 2

Yea sorry I really appreciate the help though! I will keep digging and if I find anything I will keep this thread updated.

no worries. I hope you find it!

Sam,

I just looked in the 2001 FSM, and it says, also, Front bumper, right support for JC3.

The horn grounds go to JC3, as well as the ABS controller, and the RIGHT park/turn signal.

Thank for the update. That must be correct i am going to have to dig a little further and see if i can find that connection. Hopefully i can i will keep you updated!

I spent some time looking for joint connector 3 this weekend but i had no luck finding it. I started on the right side bumper, check underneath near the frame and then behind the front right headlight even took off the battery rest. I could find anything, i then moved to the other side looked underneath by the fram and followed the wires up and saw no such connector...this one really has me stumped.

I believe it's under break booster on inner fender well!!
