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

If it were me and unless I had power previously (and perhaps if you have) check you havent got an immobiliser.

Also I would check I had 12v at the hot post if the whole CE is dead

Btw Roger does some much better wiring diagrams apparently. Haven't got them yet but they are on my list

The Porsche garage who had the car 3 years ago said he he had disabled all the immobilisers prior to him getting it started. from that point it was stood got sold as part of a job lot and to me so something has happened since then and now

You should deinstall your Glovebox. Above the Box is the round stabillation bar. Between the bar and the insulation sits the Alarm Control Box. You should Look If someone disable the Box with a cable Bridge. If not you should do it!

It looks like ignition switched 12v enters the CE panel on connector A pins 4 & 5.
