Why use the 5 speed harness if your car has a harness that will work perfect? When people do LSV do they use DC2 harnesses? When people do Bseries swaps in SOHC civic do they get integra harnesses? No, they add the extra wires needed for multi point injection. In our case we won't be needing the auto TCM so those wires are deleted.
By the way, you cannot use a 5spd ECU with an auto harness, it won't plug in, you'll need a jumper.
The vss is plug and play, wire up the wires from the shifter to the reverse switch, and cross the proper wires for the key. Don't make it hard for yourself, just look at it in steps.
The auto half shaft is the same. You'll need something to cut metal because if you look under the car, the section where the stabilizer bar and linkage bar runs, is blocked. I have 99% of my conversion parts.
