electrical and ignition engine bay wiring questions

[Reuben-bmw]

I put in a different m10 in my 2002 and I am a little confused on where some of the wires go, It is only the alternator and starter wires I need help with. There are the two  red wires, the white with a brown stripe, and the I believe black with yellow. Most of the wires come from the same loop besides one of the red ones show going along the front of the engine compartment. Any help is appreciated, I can provide more information if I am being too vague.

The large red wire with the rubber boot goes to B+ on the alternator.  The other end of that goes to the positive battery terminal.  Not sure what other wiring you are referring to but there is a large soldered connection on the outside inner fender.  send more pics.  Also, what year car and what year engine are you installing?

 

good luck, hope this helps a little,

Forgot to say the year sorry, Its a 1975 2002 now with a bored e21 block and head with 318 fuel injection, a turbo, and megasquirt. Just getting the final buttoning up before I can try to get it started. Do both these wires go to the starter?

Heres the engine, mostly together but a few parts that still need to be installed
