Fuel pump relay need advise

Hey guys this is the third relay I replace in 3 months any suggestions. I have a 83mm pulley and tune otherwise stock.
first time it burned I replaced the whole connector and I also already had both pumps replaced under warranty.

my guess is the wiring harness needs to be repaired. I’m going to bet the wires are REALLY crunchy

do that and you should be good to go
