Rewiring Oliver 770

I bought a project tractor-an 1965 770. It has flat top fenders and plastic grill and came with a factory installed alternator that had an external regulator. The wiring has been cut(butchered) and spliced in several places. The gages, buzzer, and idiot lights do not work.
I want to replace the original alternator with a single wire alternator with an internal regulator. I do not have a wiring diagram for this tractor. Can someone provide a marked up wiring diagram for the 770 that uses the single wire alternator and shows how the gages, buzzer, and idiot lights are to be connected with the alternator and battery?
I bought a new harness from Korves and they told me I should use a generator wiring harness because that would be easier to accommodate the new single wire alternator so I followed their advice.
I want the gages, buzzer and idiot lights to work properly after I am done and do not want to short anything out. I bought a new cluster gage for negative ground also. Any help or advice would be appreciated.
Thanks.
 
If you use a one wire alternator you will lose the function of your idiot lite and have no charge/non charge indication.

Get 3 wire Delco alternator for early 1980's GM vehicle. #2 pin on edge to output stud. #1 pin on edge to one side of idiot light, other side of light to switched 12 volts.

Check partsforolivers(dot)com for wiring diagrams
 
check with Steve at B and B custom circuits. He probably has all the info you need, may have any parts you need.
 
This is how I did mine.
