Not sure what op question is, but a direct connection from camera to the on-camera flash is always necessary.
For example I have used an AF160 on camera with an AF 360 in optical slave mode on a Yashica Table-Pod.
Also an AF360 directly on camera with a pc ( shutter) to hot shoe cable as shown on the above photo of the 90LS on a home-built camera.
Typical settings from my notes with the AF 360 as a remote, using the AF160 to trigger it:
Iso 100 film, Outdoor 3.5 metre +, set the 90LS to f/8 and 125th, set the AF360 slave 2, Manual 1/1 with screen retracted, 0 degrees
Indoor, shutter 500th and screen down,rotate the flash up to 45 degrees, etc
JJ needs to run a roll with various settings and positions. C41 is quite forgiving of incorrect exposure +/- 1 EV or so.
Blue haze and noise in the black areas indicate under-exposure.
Hope this gives a starting point.
