2018 JEEP WRANGLER

Guys,
I have this situation. 01/18 Jeep Wrangler ( Smelecom DSP3+)
I tried doing it OBD2 with the SGW/CGW bypass, I was able to do PCM/SRI miles
I was not able to do the cluster, I tried Chrysler wrangler menu , would not read
So I tried everything else under chrysler/Fiat/Alpha, and it read under chrysler pacifica 2017-UP menu, reads correct miles but does not allow to write, gives error "0075 failed to access 2 "
So I took the cluster out, looking for a 95320 chip, not there, looks eeprom-less. I see a microprocessor R7F701422.
Then I compared the cluster to other chysler clusters, and found that it looks similar to dodge charger, and smelecom gives pictures how to connect direct to the cluster and program ( +12, grnd, can+,can- and 100ohm-1k resistor)
I did that, would not read with 100,120 or 150 ohm resistor between pin 12-13 under the charger or pacifica ( pacifica read obd2) menu
So I went with 330 ohm resistor, now I'm able to read under pacifica menu, just like I did by obd2, but it still does not allow me to write.

any ideas....
