ok before you do any of this ...... your in mass are you going to tag and use this on the street ??? if so when doing a swap you will need the obdII and all the emission stuff off of the 2000 i would check here http://www.vehicletest.state.ma.us/
and also talk to some of the inspection stations...
The On-Board Diagnostics (OBD) Test Massachusetts uses two types of emissions tests: On-Board Diagnostic (OBD) for most vehicles and Snap Acceleration Opacity for heavy duty vehicles that are not equipped with OBD systems.
On-Board Diagnostic (OBD) tests are given to:
Model year 1996 and newer passenger cars, light trucks and SUVs
Model year 1997 and newer light-duty diesel vehicles (8,500 pounds or less)
Model year 2007 and newer medium-duty vehicles (8,501 to 14,000 pounds)
Model year 2008 and newer medium-duty diesel vehicles (8,501 to 14,000 pounds)
The Massachusetts Vehicle Check on-board diagnostic (OBD) emissions test is designed to ensure that your vehicle keeps running as cleanly as it was designed to run, which in turn protects the air we breathe.
The OBD test typically takes about 3 minutes. The inspector connects your vehicle's on-board computer to an analyzer in the station, and then downloads engine and emissions control data. The analyzer checks several OBD system functions:
Communication. Does your vehicle’s OBD system communicate with the analyzer? If your vehicle’s OBD system cannot communicate with the station’s analyzer, the OBD system must be repaired before the emissions test can be completed.
Readiness. Is your vehicle’s OBD system “ready” to be tested? As your vehicle drives, the OBD system checks the performance of various emissions-related components and systems. If the OBD system has not performed enough of these self-checks, your vehicle is “not ready” for an emissions test.
OBD Vehicles Exempt from Readiness Checks. Some 1996 and newer vehicles exhibit unique testing characteristics that prevent them from receiving a complete OBD emissions test. These particular vehicles will skip over the readiness checks and go directly to the MIL (malfunctioning indicator light) check.
Diagnostic Trouble Codes (DTCs). Why would the OBD system turn on the Check Engine light? These indicators are diagnostic trouble codes that indicate which systems or components are not performing as designed. Reviewing these codes is the first step in diagnosing an emissions-related problem. These codes, along with other information in the OBD system, help guide emissions repair technicians to faulty parts and take the “guess-work” out of the process.
Check Engine Light. Is the Check Engine light (sometimes labeled as “Service Engine Soon”) turned on? When this light is turned on, it indicates that one or more components of your vehicle’s emission control system is not working as it was designed to work, and repairs are needed. If the light does not turn on when the OBD system tries to turn it on, this problem must be corrected.
The results are printed on the Vehicle Inspection Report (VIR), which the inspector will give you when the inspection is finished.
If your vehicle passes both its OBD emissions test and its safety inspection, it is issued a new sticker. If OBD detects a problem with your vehicle (generally indicated in advance by an illuminated "Check Engine" or "Service Soon" light), your vehicle will fail its inspection and will need to be repaired.
The most common causes of emissions test failures include:
Malfunctioning components that regulate fuel/air ratio, such as oxygen sensors
Exhaust gas recirculation (EGR) valves
Evaporative controls, including poor-fitting gas caps
Sometimes, a vehicle will fail or be turned away from inspection because its OBD system is "not ready." This simply means that the OBD system did not have enough valid data to evaluate the vehicle’s emissions control system. This may be because the vehicle's battery was disconnected recently, perhaps while repairs were being made to the alternator, starter, electrical system, engine or transmission. Usually, a week of combined highway and city driving will reset the OBD system so that it will be ready for testing.
The VIR provides information that a repair technician can use to diagnose your vehicle's problem, fix it before it causes more air pollution, and spare you from more expensive repairs down the road.

Emissions Testing of Heavy Duty Diesel Vehicles
“Snap acceleration opacity" tests are used for diesel trucks, buses and other heavy-duty vehicles that weigh more than 10,000 pounds (Gross Vehicle Weight Rating) but are not equipped with OBD systems.
In this test, the inspector uses an opacity meter or “smoke meter” to measure the smoke from the vehicle’s exhaust pipe. The darker the smoke, the more the vehicle is polluting and the higher its opacity reading will be.
The inspector first secures the vehicle safely (so it cannot move) and tests to ensure that its engine governor is functioning properly. Then the inspector presses on the throttle to bring the engine up to its maximum governed revolutions per minute (RPM) several times - first to remove loose soot from the exhaust pipe, then to measure the opacity of the vehicle’s emissions.
Readings from the final three acceleration “snaps” are averaged. The final average is compared to the emission standard for the model year and type of vehicle. Newer vehicles have more sophisticated emission controls, and must meet stricter standards.
