70 Engine Harness

Are the 1970 Engine harnesses combined with the headlight harness? I understand 70 was a transition year for quite a few things. Then in 71, they became two harnesses? I ask because I bought a reproduction 1970 engine harness but it didn't have the Headlight harness with it and my 1970 Swinger kind of had a hodge podge harness going on so I'm not sure what is exactly correct for 70.
