If you want to swap your SOHC (single over head cam) engine out for a DOHC (dual over head cam) engine, this is the information that you need. "(however this information will help with the person wanting to swap DOHC to SOHC as well)"
did you read any of the link?
This is a good part!
"Make sure the wiring harness will work with your car. If you have a 96+ engine, you need a 96+ harness. If you don't want to buy a wiring harness, you can convert your stock SOHCharness to work the DOHC engine. It requires more work and custom wiring.
To convert a SOHC harness to DOHC, you need to change the cam positioning sensor plug, and extend the coolant temp sensor plug, it needs to be long enough to reach passenger front side of the head.Sensors may not be plug and play. You may need to buy new sensors for certain applications or use the sensor form your other motor.
If swapping DOHC to SOHC the harness will be long enough to reach.
There are some differences to some of the harnesses depending on the year:
(early 97 wiring harnesses are odd, they may have differences such as VSS, alternator, brown wire that goes to the starter, TPS, and the IAC motor all have different plugs. From what I can gather it is a Frankenstein harness between the 96 harnesses and late 97-99 harness
1995 PCM has a single plug that connects to the frame, motor, and cabin wiring harness.
1996-1999 PCM has two plugs that connect to the frame, motor, and cabin wiring harness.
1995 model year has unique plugs for almost all the sensors in the engine bay.
1996 model year is a hybrid between 95 sensors and 97-99
1997 - 1999 No changes were made to the wiring harness between these years... use all the same sensors.
1995 has a separate MAP and IAT sensor.
1996-1999 have an integrated MAP / IAT sensor.
1995-1996 use the PDC for the fan relay.
1997-1999 use a separate fan relay located just below the driver side headlight.
1995-1997 use Bosch plugs for the injectors.
1997-1999 use the USCAR square plug
The plug change happened mid year so some 97's have Bosch style some have the USCAR style.
1995-1997 use the same alternator and starter.
1998-1999 use the same alternator and starter.
They only fit the correct years harness.
IV.DOHC Motor Mounts
There are two different types of motor mounts. There are steel mounts and aluminum mounts. The steel mounts are interchangeable; the aluminum mounts will only work on the type ofengine they came off of. If you have the aluminum mounts, you will need to buy new motor mounts. "
