S2 1984 non starter

Im still chasing the issue on my 928 s2 1984, first issue most wiring diagrams dont match my CE board, in the picture i have attached the terminal on the far right has a yellow wire this is the starter wire from the ignition switch no drawings i have found has this wire there.so im having issues finding the relevant cables im looking for. Issue with starting is as follows im not getting any power to the CE or the coils when the ignition switch is on ive changed all the relays and the ignition switch but im not getting power to the activation terminal on the relays. From all the other diagrams i have looked at terminal 15 on the ignition switch is the feed for all the relays i have power at the switch as should. i have installed new relays since picture. Any ideas or if you know the S2 EU which terminals feed the CE form the ignition switch

It appears that your 928 is a EURO/ROW with the first year of LH/EZF modules. Most documentation on-line is for the US L-Jetronic system.

The attached documents show the Euro Central Electric. I hope this helps.
