I have a 2000 ford expedition 4x4. I am installing a suppercharger on it the motor have in the truck now is a 4.6 . The truck is a 2001 that I bot has a 5.4 I bot the hole truck it is a 4x4 I need help to in stall the supercharger from a to z . On how to hook up the emision hoses on th suppercharer please help
Intake, midplate, and SC install complete:
With the intake, midplate, and SC now installed, we moved onto the IC lines and vacuum harness. The IC lines consist of two black steel tubes that bolt to the passenger side of the SC and connect to the IC with 5/8” heater hose elbows. The other ends of the black steel IC lines were hooked up later.
Let’s take a moment and discuss the vacuum harness. The Lightning uses a boost by-pass solenoid and a barometric sensor. Because we used our original Expi wiring harness and computer, we did not need either of these connections. These two devices along with the EGR solenoid and DPFE sensor are mounted on a black bracket that attaches to the driver side of the SC. We basically cut the bracket in half so that all we had on it were the EGR solenoid and DPFE sensor.
Why does this matter with regard to vacuum, well…without the by-pass solenoid or barometric sensor, the stock Lightning vacuum harness could be trimmed down. We removed all the lines that would connect to the boost by-pass solenoid and the barometric pressure sensor. If you look at the harness with relation to the sensor positions, it should be fairly obvious which ones to cut out. When I do the SC install in my truck, I will get pics of those deleted lines and update this post.
On the driver side harness, there is a black vacuum connection with a red and black line coming out of it. The ********* end connects to the nipple on the midplate (located about halfway between the front and rear of the assembly on the driver’s side). The red plastic line connects to the fuel pressure regulator. On the black line, we added a T-fitting…one end connects to a boost/vac gauge and the other end connects to the top nipple on the boost by-pass motor (black vacuum motor at the upper driver corner of the SC. This motor remains in the open position during non-boost moments (idle, cruising, etc) and the closes during hard acceleration (under boost). Its purpose is to release boost back into the plenum when it isn’t needed. We will address the passenger side vacuum lines once the plenum is bolted on. The bottom nipple on the by-pass motor remains open/disconnected.
At this point we attached the plenum, throttle body, and throttle cable/cruise control cable bracket. Back to the vacuum lines from earlier, there is another ********* vacuum connection that wraps around the back of the SC assembly toward the passenger side and attaches to the plenum forward of the IAC motor.
The final vacuum connection was a black plastic line that ran towards the passenger fender. This is the main feed for the Expi’s vacuum system. We just plugged it into the rubber hose that our original Expi vacuum harness plugged into.
Did you keep the boost by-pass on? My wire harness does not have connections for the boost by-pass solenoid or barometric sensor, so I am just wondering if I can just leave it and the vacume hooked up or if I need to delete it all together?

My question is, if I were to obtain an entire 5.4 Lightning Engine and ECU, would it be a direct swap into a 1998 Expy with a 5.4 already in it?
