hi guys 2022 maverick lariat here, oe is sync 3. im looking to do the sync4 upgrade as well as the larger 13.2 screen from the escapes. i have a few questions

power plug on the back of the new screen, not the six pin apim to screen connection. the 4 pin power for the larger screen. which pins are power and ground? and is that power just switched ignition or is there somewhere specific that it needs fed from?

secondly the sync3 plug needs two pins removed from it before its used on the 4 apim pins 53 and 54? those are just removed from the connector?

finally does anyone have a maverick lariat sync4 asbuilt i can use to start with

thanks in advance
