Keith there is very slim chance you will not find that relay on the forum, specifically a new one, cause it has been mention B4
That GM relay was not very reliable,so there was good batches an some bad batches. Lots of our members just unplug the thing
because it just engages prematurely an runs there battery down.I'm fortunate to still have the EOM relay and it works find.
You can get and aftermarket one from Kirban , Hwy Star, or Caspers. Good Luck...
