98 to 99 ebcm swap

hi
I have a 98 ls1 stock Camaro and I did recently a 411 99 PCM swap.
The problem I have now it's that here in France it's raining a lot

so I would like to have my traction control TCS back.
Looking at the wiring diagrams it seems (to me) that the 99 ebcm might work on a 98 car with some wires moved (but I'll lose some indicators from the cluster).
Can someone confirm me that?..

The only problem for me can be that the pcm and the ebcm will need a programmings to make them communicating..

Of course it's working. 🤠
About the wiring I've just moved the 24 tan serial data wire to 25 place and relinked on the obd connector the ebcm 24 (now 25) tan wire to the 2 ppl pcm wire. The traction control is working but the low track light in the cluster not anymore. The abs light is always on in the cluster but the abs system is operating. There is no default in the pcm but in the ebcm module the tech2 is giving the U100 default (2 serial data link - faulty system).
Voilà
