In the process of doing the na turbo conversion. Taking a donor '89 spg and turboing a '93 900S with the 2.0 motor, APC, Inter-cooler, ignition ect. ect.. Everything has been swapped out and am now switching the ECU harness's so I can use the turbo ECU.



I've pulled the 2.4.2 harness out of the '93 and have compared the connectors between the 2.4 and the 2.4.2 along with the schematics and it all looks good. Just still confused with the wiring for the a/c at the H6-2 (67) connector. Pin #5 red wire is left out of the schematics. And pins 2 and 4 go different ways on the a/c schematic. Even though the wiring colors are the same on the H6-2 (67) harness connector (as though it could just be plugged in) I'm not sure if it will work the a/c without some changes.


The Bentley wiring diagrams in question:

'93 900S: 2.4.2 Fuel System 371-70 and Air Conditioning 371-17

'89 900 turbo: 2.4 Fuel system 371-66 and Air Conditioning 371-16

Connector in question is H6-2 (67)



Anyone have a clue as to what to do if anything to be sure the a/c will work with the ECU harness swap? And any input would be appreciated.
