Need help with wire identification electronic harness!

I see where confusion is... We're talking about 2 different wires. Yellow wire start signal from ignition switch to starter relay then automatic trans gets a brown wire kind of thrown at it to neutral safety switch. This member now knows what/where his brown wire is for so... its all good.
You're right. My mistake. You were explicit and I read it too fast.
the brown wire from starter relay to neutral safety switch wasn't taped in a harness or through the bulkhead
The wire to the NSS on my '67 was seperate from the wrapped harnesses.
