Dash wiring harness routing

[JAM72]

I am about to hook up my new dash wiring for my 72. I do not have the advantage of having taken the old wiring apart as it was all stripped out before I bought this project car. My question is how is the main harness from the firewall main connector into the dash  cavity? There appears to be an opening at right (looking from the back as per photo) bottom for cables to enter although it may be a struggle to fish all the wiring and connectors through it. I expect some or all wires may just be fed up from below wherever., however it looks like there is a large cable holder in the bottom left area which could indicate the main harness should come in bottom left.    
Does anyone have the answer or a photo showing the correct routing?

I can get some I have saved along the time for diff reasons. Despite the red circle on the last one. I was showing the Conceleaded headlights relay location and when I saved the edited image forgot to rename it to keep untouched the original file

Thanks Nacho-RT74
That helps a lot. I see the main tree just goes basically straight down to the connector. The hide away head light relay location is also helpful as my car has hide aways  :2thumbs:but the new wiring kit does not include the relay and wiring. I may be able to find the old relay from the existing mess or I can buy a new one. I will wire it in per the shop manual.

Thanks again.

New relays are not available unless NOS... sometime ago repros were available but I think not anymore. It can be replaced with a 5 prongs Bosch kind relay thought.
