[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]Now time to start the wiring for this rig
[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]It all begins at the starter, alternator, ac and low oil level harness from the 98 5.0 104K donor
[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]harness is cleaned and repaired before install
[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]
[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]I can use this harness as it is, no mods needed
[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]typical repair of the factory wrap
[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]
[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]transmission / 02 sensor harness is getting cleaned up, this dude will need some mods for our build
[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]
[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]FYI the wiring harness are the dirtiest part of a build! much time is spent wiping them down so I can work with them
[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]So when Brett built our 4r70w we make sure to use the 98-01 style bulk head wiring connector along with its corresponding internal hard wiring harness and 98-01 style solenoids
[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]Half way through 97 the 4r70w changed from 9 wires to 7. I needed to make sure I had the correct harness/bulkhead fitting before plugging it in
[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]
[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]7 wires we have the correct harness, no mods needed
[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]I keep this chart (along with many others) pinned to the wall in the shop because I am often making changes to these transmissions
[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]
[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]Now inside the 5.0 transmission harness is also 3 of the 02 sensors. This truck will be using a single wideband 02 sensor with the Holley drivetrain computer....so I removed two of the 02 sensors and their wiring. I will route the bosch 02 sensor to the holley computer using the factory wires and blue plug
[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]
[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]time to unpin the removed wires, harness is cut down and 2ea 02 sensors go bye bye
[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]
[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]
[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]Harness will be re wrapped and installed along with the transmission case vent
