Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
Hello I will help you with your question,
The receptacles are fused at 20 amps so you can run this from the receptacle BUT I have seen this type of device damage the receptacle so to be safe and to run this you will need a dedicated circuit from the battery. You can connect an inline fuse to the battery positive with 14 or 12 gauge wire, install a 20 amp fuse and a lighter outlet to plug the heater in. Outside of installing a dedicated circuit there is no safe way to operate it with your system.
Please let me know how I can help
