510 KA24DE Wiring issues.

[Goosie_the_xiii]

Alright, this is what I'm working with. Here are some photos of the original harness 

 

Here is the fuse box and the wiring coming off of it.  ^

 

 

The white wire off the fuse block. It plugs into the W/R and the W. It looks like whoever did it also spliced a W/R wire off the W wire. It runs to the alternator. ^ 

 

 

I followed both of them through the harness and they both come out here. ^

 

 

The W was spliced and a piece of wire was added to lengthen this connector. ^

 

 

The W and the W/R (from picture 2) meet at the alternator. ^

Look at the drawing I posted CLOSELY!!!!!!!. That is correct. at least for the orginal 510. I see the KA connector plug in on the alternator . I really dont know.

Skimmed quickly so I may have missed it, but sounds like the box is losing power when you try and start it? 

 

Where are you pulling the power from?

If you are drawing any power from the ignition switch you will need to splice two connects to ensure you keep power during cranking. All my cars have been rewired so this may not be relevant to your situation.
