Mine is a name brand switch that so far has held up fine. I'm thinking maybe it came from Painless or Holley. Probably made by the same co. as the Echlin! You can also source this switch by asking for one for an 85 Eagle 6 cyl. They used the two terminal pass through to power the undercarb manifold heater. The heater drew so much power they smoked the switchs left and right. We would bypass the switch. Then you had to warn the owner to be careful as it would kill the battery if they sat with the key on and the engine not running.
