Mystery Wire - 88 420 SEL
 

Help
I have a mystery wire in the wire harness to the Ignition mod
Brown with a red stripe.
My wire diagram does not show this color.
On the large pushin terminal that goes to the mod. I found some elect. tape when I pulled it off there was a wire (brown with red) that was not connected. I took apart the harness to the firewall and I have not found the other side of the wire.
The car runs for one hour then dies. no spark.
Changed the
Coil
Ignition mod
Idle speed control
Fuel pump relay
