Slip/Abs/brake light all come on after tire change and 4.08 install problems

Chasingstatus

Hey guys I hope this hasn't been covered already I couldn't find any info in my searches due to the nature of the question. Basically after about 9.6 miles on the odometer my slip, brake, vdc, abs lights will light up. I installed 4.08 gears over the winter and everything is hooked back up correctly, wheels speed sensors and all. here's where I think my issue is though since I don't see others with the issue with gears. I am running a 255/35/19 front and 305/35/19 I remember there was a calculator or something that told you if your sidewall heights were within a certain number from each other to keep the speed sensors happy since the rears are a lot taller than the fronts. I cannot remember where this link was or how I found it but I am hoping for that since the gears make no noises and perform well. thanks in advance

Also brake fluid level is good
