69 cutlass.
I recently installed all the fuses that were missing in the box and discovered that when you install the fuse that operates the trunk and underhood lights.
The running lights stay on.When this fuse is removed the running lights still work fine.Any suggestions?

 

This is known as a feed back.I have traced these down B4, First start with Cigar lighter,s ? Remove them or disconnect power wire,As they are fed through same circut.Sounds Krazy but so is electricity.
