lights question

[idiburner]

hey everyone i just finished wiring up my goose-neck trailer. but a problem when i turn on the turn signals like the left one is blinks at a different rate then the truck and it causes the right turn signal to dim and re-brighten like it was flashing but its not and its the same when the right turn signal is on but the left is dimming. is that a bad trailer or truck socket? bad wiring? the wiring i used is just normal 4 color 4 pin wiring but i just split it and ran it since i had a whole role of it. could it be a bad ground? any help be much thankful as i got to pull it today.

Well usually I've found on weird deals like that it is often times ground related.

Ground issue 75% of the time. Get a multimeter, set it on continuity mode, and check every connection to see if it's properly grounded (if it should be) or properly connected to the truck circuit.
