You need to remove the air filter and disconnect the electrical connector from the meter. Loosen the hose clamp and remove the screws that retain the air flow meter to the air cleaner housing. Istallation is reverse.
There isn't a 1997 Plymouth Laser they stopped making them in 94 but if you have a 97 dsm (talon or eclipse) it should be on the right hand side of the engine block Here's a diagram for it http://members.shaw.ca/dsm.1000q/Engineprimer/2G/alt.htm
Behind the exaust manifold there is a machined flat plate that will have the numbers engraved on it. Since your asking about the Plymouth laser,due to the limited production years(given it is a DSM, 1990-94) the engine is most likely the 4G63 for non-turbo and 4G63T for turbo.
if your talkin about the ecu(engine control unit) any 1990 dsm (talon, eclipse or laser) non turbo ecu will fit the 1991-94will fit after mods to the 6 pin an 14 pin an coil pack wire switched
The codes from these cars and the data port are unique. You can buy a cable and palm pilot equipped with the software to read the codes on Ebay for about $50. Search for DSM datalogger.

DSM-V
Diamond Star Motors also known as DSM. The company consisted of Mitubishi Motors and Chrysler Corp. The talon was sold under the eagle badge by Chrysler to compete with Japanese imports. After Chrysler purchased American motors in 1987, the sisters, Laser sold by Chrysler and eclipse sold by Mitsubishi were manufactured. Eagle and Plymouth have since been discontinued.
On a 94 Turbo DSM there is no crank angle sensor. The Cam Angle Sensor(CAS)serves the function of both a crank and cam sensor, and it's located on the passenger side of the valve cover at the end of the intake camshaft, you can't miss it.

DSM-4 WAS PUBLISHED IN 1994
I don't see it in the DSM II published in 1968. It is in the DSM III published in 1980.
The DSM IV Diagnostic manual was first published in 1994. The DSM IV - TR is a text revision published in 2000. So the most current edition is indeed the DSM IV - TR. The DSM V is due in 2012 and may be very different from the current style. See http://www.psych.org/mainmenu/research/dsmiv/dsmivtr.aspx for more info.
