hi anyone out there know what the TCU A10 pin marked as "ILLUM CANCEL" does I suspect it is used to send fault codes to the "S" 0r "D4" indicator light on dash.
used on multiple TCU,s preludes accords integras.

also anyone know where I could get a copy of a service manual for 93 JDM prelude.
help with this would be greatly appreciated.
