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!
