Mystery module
Could someone identify this module for me? It's in my '87 S-10 Blazer, 2.8l 2WD. It is located on a bracket attached to the ECM (1227429). The box it plugs into has 4 wires connected to it. I was just curious since it has a lithium battery in it which surprisingly still reads 3.4 volts. Not bad for 24 years!
