Wiring - Tying into TJ harness (Part 2)

 

Here we see the location of the AW4 gray and black 8 way connectors. After the transmission is installed run these up the firewall on the passenger side of the motor. This is where they will connect to the harness you have been making.

 

Here is the temporary state that the TCM is suspended in. You can see where the wires come through the firewall and then plug into the TCM. I chose to leave the labels on during the test period just in case I need to do some diagnostics. Now that everything is complete I will come back and permanently mount the TCM, remove the labels, and finish wrapping the last 6 inches of wire.
 

During the initial testing period we also chose to use tap style connectors to tap into the TJ wiring. Now that everything is working correctly we will solder some pigtails into the TJ harness that will end at some Molex connectors. Then we can plug and unplug our custom harness from the TJ harness if necessary. Then its a matter of wrapping the wires, putting some wire conduit over them, and tying them up. When complete it will look as neat as the factory wiring. 
 

Like I said before, this is only temporary!!!
 

That completes the temporary wiring portion of the swap. Let's move on to getting this thing installed!
