1206 is a series of controllers with a letter or number after the 1206 to identify the options. What was your full model number on the old controller? You say it does not have 5 pin connection? What did the old one have?

Customer: replied 1 year ago.
It has 3 individual wires with slip connectors next to the B+ connector and 1 next to the B- as for full model number on the old controller I haven't been able to locate any. The EZGO new controller has a G633 tag on it.

The old controller looks very much like the G433H 36 volt 350 amp

Amazon said that this new controller G633 was a more powerful upgrade to create more speed

Here is the typical diagram.

Where do the existing wires come from and go to??

Customer: replied 1 year ago.
I'm sorry but it's obvious that your an EZGO mechanic. It should not take this long to identify if I have the right controller. Which is now obvious to me by my own research. Thanks for your efforts.
