Looks pretty similar to the 70 Dearborn routing . Can't find a picture to verify the two outer studs at the taillights were used with the metal J clips as shown in the assembly drawings and on Dearborn cars in the other thread but here is much of the routing and look from the wheel well on the drivers side to the tail light on the passenger side
Hope it helps
Pic #1 Red arrow shows the typical white/opaque colored zip tie. Extra wire connected at the top is the trunk light that this car came with, connection point
Pic #2 Fuel sender routing and tape locations
Pic #3 Driver's side tail light. As mentioned can't clearly see the outer stud (green arrow)
Pic #4 Routing along the tail light panel Blue arrow is the grounding location for the loom
Pic #5 Passenger side tail light. Take notice that there are screw protectors and stud protectors used on the tail light mounting hardware on the trunk side
