How difficult is replacing the ignition switch on a 70 383 Roadrunner? I don’t want to call a mobile mechanic to do it and pay him $$$ if it is something simple I can do myself. The switch comes with the wiring harness so i’m assuming it is a plug and play application. Any information or links help. Thanks.

 

My 69 was plug and play. Easy. Right on the firewall. 1/2 wrench and lugs. Disconnect the battery first. Took me 5 min... If you mean ignition relay. Do you mean the key switch? That is easy too if its like mine in the dash. Just a connector.
