2G 1g wiring harness, accessory harness, and ecu in a 2g gst?

[John Miller]

I am wondering if I can swap a 1g engine harness, assecory harness (the one that goes around to the radiator fans ect) and an ecu all from a 1g gst into my 2g gst which will have a 7 bolt 4g63t engine. Is this swap easy and what does it require.

Thanks

Anything is possible but swapping the harnesses and ECU from a 1G into a 2G isn't an easy task.

I'd guess it's at least twice as much works as just swapping the engine into the 2G. Additionally the 1G ECU is a step backward being ODB 1 vs the 2G's OBD 2 and depending on the year 2G won't pass federal emissions testing.

So, the first question I'd ask is why that route?
