Proper harness routing

[dcmason69]

Looking for proper routing path for neutral/park - reverse lamp harness on my 69 Coronet!
Down firewall and follow along top of Tranny ?
Or over booster down apron and along Speedo cable?
Auto/power brakes
Thank you

Across firewall near heater hoses, then down the top of trans to the switch. I think they did this to keep wires far away from the moving linkages
