Default Electrical Problems- B/U & signals

Im new here. Maybe a Mod can help put this in the proper place.

I have read many threads on multiple Dmax forums but have been away for awhile as my truck was running excellent. And i'm back, i started a new account and still have yet to finger out how to do my signature and am unsure where to post my problem. This is my second Dmax, I also have an '03 LB7 120Kmiles CCLB 4x4 6" Fabtech with EFI Live

I have a 2006 Chev Silverado 2500HD (102kmiles)LBZ CCLB 4x4 6" Fabtech EFI Live DSP5 CTS2 with All LED lights. I've had it a year.

Recently ive noticed a fast flash developing in the signals. Anyway i was installing the new 2015+ Spyder Mirrors w/reverse lights (should have gone boost mirrors)on the LBZ and put the LBZ mirrors on my LB7( which are bitchin" and work great). I pulled the wire thru the doors and spliced to a wire i ran to the underhood fuse block(b/u trlr) where i tapped power. when i put it in reverse, it blew the 10amp fuse, not having a 15 i put in a 25amp. (Idiot) Now i have no power at Trlr B/U but i do at (B/U) and my reverse lights dont work. No power under dash on green wire for trailer either. No power under underhood fuse block for b/u trlr either. What burnt? BCM reflash needed? PRNDL works. hmmm?

Now i learnt after installing the mirrors and reading some forums about the dual function of both the reverse lights and the signal/drl, ill wiring that up using the correct wire harnesses from boost after i finish [email protected]#king this up.

Also i lost my turn signals.. wtf? Hazards work on the driverside only. right turn fuse keeps blowing. not the bulbs right? i swapped flasher from LB7 (which works) into LBZ same thing. not the flasher then right? Short? where? The truck was allLED when i bought it. Do i need the GM 10383322 ($78) LED flasher from Rock Auto?

Thank you in advance.I look forward to yalls help.
