youre better off getting a different flasher relay otherwise you defeat some of the purpose of the led in the first place. let me see if i can find you what you need. i should have it somewhere, since i did this a while back myself
here is a link to the one that worked for me:
i picked it up at a local truck/trailer store for like $12-$15

bit of a pita to change out but not too bad, you have to unbolt the inside fuse panel to get to it, (it plugs into the back of it). on my 2000 there was a small adapter piece inbetween that ommitted one of the pins on the relay. I removed that, plugged this directly in, and it works like a champ.
