After a complete OVERHAULIN body & PAINT work on my SSE88, the SECURITY light is blinking at all time now and this at the moment I re-connected the battery cables on.
I suspect that one of the 6 ground wires is broken somewhere
falsing the alarm system that one of the 6 car opening is still open.
My search in my repair manual permitted to discover a key ground wiring location named S277 where all 6 "blue wires"
are connected together...however the book do not say where
this S277 connection is located on the car.
This is the key location to identify which one is defective.
Is anybody can tell me where this S277 sshould be located?
Thanks

Thanks for the advice.
I wish it would had been only one of the 6 switches being faulty.
All switches have been tested one by one and unfortunately this was not the root cause of the problem.
The interior lights open when the doors are open and shut normally when the doors are closed but the security witness light is just blinking or stay on when the alarm system
is armed.

I noticed along the body restoration that there was alot of rust at bottom of the doors and floor (due to water infiltration) and the electrical wiring network had suffered of this.

Now to trig down the faulty wire, I need to find where the one wire from the SECURITY module reach the 6 wires harness.
From this harness I will be able I think to proceed by elimination and detect the faulty one and repair it.
I would like to locate where is that 1 to 6 wires connexion
is hidden on this car... before I take the entire dash apart
...any idea?
