There won't be any wiring differences. In the previous posts the terms computer and SBEC are used synonymously. What the aforementioned vendors usually do is take your computer (also known as a Single Board Engine Controller--SBEC) and remove the ROM chip in it. They then replace it with a chip with custom code. To quote the FWD performance website they take your computer and they reprogram it for
"... pounds boost, revised spark and fuel curves , and modified wastegate tables for faster spool up. O2 feedback, active knock retard, increased rev limiter and over boost protection provided. Revised fan schedules for better cooling"
Some vendors will then ask you for customized options about this custom code. Some may include code for the charge air temperature. In this case you may have to add a wire from your computer to this new sensor. This is an optional step.
One of the previous posters mentioned the AIS and TPS. For a 1992 model that is irrelevant. There will be no wiring change in these sensors.
So in short, no wiring change unless you opt for a charge air temperature sensor.
