    Default hi, need some help with 2016 buick enclave correction

    Hey so i have a 2016 buick enclave im trying to correct, unfortunately the vehicle is not available for obd correction to make it easy job. So im stuck with the turd SOT-23 93c66 chip. For manual reading writing i am limited to two tools currently. A digi3 clone and a upa-usb v1.3 clone i think, ebay jobby at least. My question would be does anyone know of or have seen a pinout for wiring say a digi st47 plug to the sot-23 chip? or possibly a wiring diagram to wire upa to this chip. No need for board wiring locations I can micro wire directly to chip legs if need be. Thank you for any help or info you can provide, much appreciated.

    I do see a earlier post from someone with a arcadia 2016 upa pinout and my board does match this pic exactly. but no number 1 shown on pinout and im not sure how theyre numbering of the pinout correlates to the upa connector without colors listed. I guess i dont know how to decifier positions unless it just means the number on pic goes to the number on connector for any old eeprom like 1 is 1 2 is 2 but again no listing for number 1 pin which i assume would be cs and probably needed. Anyway Dont mind me banging my head on the wall :>

    UPDATE: SOLVED Next time instead of asking a stupid question, i should try provided solutions in the forumns first . haha Anyone in this situation should take heed of my advice :/ I was able to just connect out just like pinout shows pin number for pin number with upa-usb v1.3 Reads and writes perfectly. Now for some attempted calculations :>
