Wiring help needed

Can you guys verify this? The wire in the pic - Brown with light blue tracer (looks tan with blue tracer) lol.
Anyways, the one end I removed it from EGR Timer, the other end connected to the starter relay?

Should I just remove it?
I'll have to dig. I might not have the right year service manual
