Carefull with these they alow alot of room for crap to get into the connections. Use dome die electric grease in the connections, and also use sylicone to seal up where the wires go into the connector. Trust me I did get stranded for a couple hours with a buddy of mine trying to clean a connection with minimal tools just my .02
also if anyone has a problem with dimming lights i fixed mine by running a heavier gauge wire i think i ran a nuber 4 or a number 6 i cant remember
