70’ Dodge Dart won’t start

Hello I just bought me a 1970 Dodge Dart custom yesterday and was in good running condition today I changed the spark plugs and while I was doing so I thought “hey I’m changing the cables either way why plug back in right ? “ well I fucked up and now i don’t know what cables go where and the car won’t turn on, I have done some research found out it could be 1-5-3-6-2-4 can anyone help me on this one, if that is the sequence, and also how can I find witch is number 1. Thank you in advance .
