Don't buy a Greentime controller or any other product from greentime.
I pledge to never buy another product from greentime and don't want another ES member to get sucked into Leo Liu's Aliexpress business vacuum.
After buying a greentime controller from him which I didn't use right away I passed the protection phase and probably his interest to help me.
Basically I have tried to find out how to turn the controller off and on when there is no ignition wire or switch. There has been only one reply that shows that he has not read any messages I sent him.
Yes I have opened it up looking for ways to connect, no he doesnt have a manual, no he did not send me the product that was in the picture I thought I bought. No the pictures he sends as reference are not the same as the product I bought. No he didn't put a purple red wire on mine.
I am not into waiting over a month from some one as lazy or rude as this seller to tell me the same information that is not information.
DO NOT BUY FROM HIM. I WILL NOT EVER AGAIN.
