GS swap to GST - Electrical problems

[Heryst78]

hi guys

Before beginning, I apologize for my bad English, I’m French

Actually, I’m swapping a GST engine on my basic GS.
Everything was ok, but now I’m in front of many electrical problems.

- There is 3 connectors where I don’t know to connect them, I put you some pictures, can you answer me ?
- Then, I have a big problem on the connection between the engine beam and the fuse box.
On my old fuse box beam, I have 10 wears.
On the engine beam, I have 11 wears now.
Do you know what is the differences between both ?
Do you a picture of the fuse box to compare the GS and GST fuse box ?

Thanks a lot

I could easily be wrong on either of these, but at first glance:

531631 - pics a little blury, but it looks like it might be for the boost control solenoid
531633 - kind of looks like a GM IAT pigtail. Is it possible your donor ran speed density?

We didnt have 4g63n/t on the 2g Eclipse/Talon in this country, not many would know the differences in the wiring between the two.

#1. No clue, looks like the connector to the fan harness by the alternator

#2 looks like the aternator output relay

#3 no clue, vehicle speed sensor

#4 , on us model cars that looks like the fuel pump prime connector. You would stick a paper clip in it and it would prime the pump.

The euro spec gs 4g63 non turbo is closely related to the 4g64 spyder. It is best to find more about that model
