Hello I know I’m new here but thought I share something with you about shorts in wiring.If you have a short all I have done over the years is to put a compass on the front seat turn the key and it will point toward the short as if it was north and you can take the compass and follow it.If it has not blown a fuse.If it has just make your self a circut breaker for that fuse and have one reset it and you follow the compass needle.I hope you get what I’m saying it has work for me for years.If you have question please ask willing to help Rich
