Hi all, I'm about to fit a Sachse ignition system.
I haven't as yet found a comprehensive wiring diagram, so I need to ID the following parts:

I think the third picture is probably the factory reg/rec. And yes it doesn't look well.

You're correct on the last.  The first two are the original Bosch BTZ ignition boxes.  Wiring diagram should be easy enough to find, it's in the back of the green book for example, titled post-79 triples or similar.
 
IIRC the BTZ has a completely separate harness from the main loom, it can be removed without affecting anything else.  Start at those big plugs on the BTZ boxes and work your way along! :)
 
If you're also fitting the alternator upgrade with the Sachse system, then you'll need to toss out the old rectifier (your 3rd photo) and replace it with a 3 phase rectifier regulator. You can usually pick up a second hand RR from motorcycle wreckers or ebay for around $50. A Shindengen 530-12 is the usual choice, but any 3-phase RR should do as long as it'll handle around 30 Amps.


 
Hey Trev,
Didn't I send you the installation manual with your system. ?

Did you source a pair of ignition coils as we discussed ?
