Check all your connections and make sure they're good

Hey all, I just had the c41 and I tried everything known to man except a new harness to fix the issue but I forgot to check 1 little thing.
The POWER COMMANDER!!!
Once I disconnected the old power commander that came with my bike, she fired right up.
Don't have the same dumb mistake I did!
