Is the positive and negative cable connected to the correct battery post? Positive post should be closest to the engine

Check your fuses and relays probly blew a relay imo
i did power test with 12 volt circuit tester on all fuses in three locations and observerd that there is no power on any fuse on driver side fuse box and no power on 1st row and 3rd fuses on passenger side fuse box.

these fuses look fine, I have swapped fuses and observerd the same pattern.

any suggestions

where should I look

If it was working fine before the battery swap. Check your cables.

My bad.. I should have been thorough while checking fuse, I thought I have checked all fuses but after giving 3rd of fuse checks Noticed 120 Amps ALT fuse blown.

from wiring diagrams it seems like this fuse pretty much covers everything in the fuse box 2 and some in 3

I got the fuse today and will keep posted after installing it.

thank you very much for all your help
