Ezgo total charge II control board replacement help!

[Tjustis2407]

I have looked on here and can’t find nothing pertaining to my situation. I have a 93 ezgo marathon and the chargers relay in control board went out. I can by pass the relay and it comes on and charges but won’t cut off when full. They discontinued the control board for the total charge 2 with the “fancy” displays and reset buttons so you have to use the control board for the other models. It just won’t support the display or reset buttons and just will charge and shutoff when full. I ordered the control board and the company said to contact them for directions to hook up. I did but all they sent me was the same wiring schematic that’s in the manual. This new control board has only 4 connects to hook up wires and my old one has about 12 or so. Which 4 do I connect to where? I’m so confused. If you have replaced your and have the same charger please help me out. Maybe send me a pic of what you got hooked up to what. Appreciate it!

The four circled connections are used. Red wire from heat sink is positive and black wire from centertap is negative.

Need to jumper the white AC wire to the transformer.

I've done that before but before I started I gutted it like a fish and removed all components that I wasn't going to be using afterwards. The off/reset, charging light, charge complete light, and their associated wiring got scrapped. When I was down to only needed components I replaced the control board with a Powerwise 36 control board. It already has the red and black wires that go to DC + and DC - and leaves nothing to connect except AC input with ground and primary transformer. One side of AC is direct connect to primary and the other leg of primary is controlled through board and relay. DC output is all left intact. A couple of years ago and as far as I know still working.
