Not half bad GM radio connector
The molding fits the GM Delco 3 radio connectors fine, but the single 2 post pigtail was not the right style for 1982 ETR radio connectors. I had 3 wires that pulled out of the larger black molded connector, which i had to take apart the connector and re-crimp the wire & connector again. Kind of a pain to do that & evidence that the connectors weren’t fully crimped at the factory. This product allowed me to keep my factory Delco connectors and install a new aftermarket radio without having to cut/spice the factory harness. Just make sure you have the tools to recrimp any loose connector wires if you buy this.
