Hey I posted in that thread! Back when I was a wet behind the ears 18 year old.
Now I'm a
slightly more experienced 27 year old.
I can see the pics Ranger80 posted, but they're pretty blurry.
I looked in my 1980 BCE manual, and I couldn't even find a listing for the clock to verify whether it shows a difference in the wiring harness. It does however show the connectors behind the dash for the light group option, which contradicts the claim Ranger80 was making.
