Thanks fellas. Have been going through those threads and some other reading ... It's amazing I work with power every day yet car electrical gives me a headache. lol
I was looking at Darrens drawing, and it is perfect for what I need... however. With that setup, when I manually turn on the light, the reverse lights will turn on too. This is something I want to avoid.
In a nutshell I need a relay that can be triggered from 2 different sources ( reverse light and manual switch), yet not interconnect those 2, if that makes sense ?
