Got a pic? I recently installed a harness and e-codes in my ZJ. Thought i had a bad relay but turned out to be a bad connection at the plug for highbeam relay.
I find it unlikely both your relays went at once, i think your issue lies elsewhere.
Anyway.. these are the relays in my harness. Their made by Pilot and sold through O'Reilly's etc.. part number PL-RY1... couple bucks a pop.
Mine are 4 post relays like these.

I installed the harness and everything was okay for a day or two, then the lights would not come back on, I disconnect and hook up the original harness and everything works fine. What would seem to be the issue?
I tried hooking it up two different times and both times after a day or so, the lights would not come back on...

I had the Eautoworks harness for a year or so, just randomly started to have problems. Did the same thing, searched all over for that relay, found them at pepboys as pilot brand. after going through 3 of them in just a few weeks, I ditched the harness and went back stock.
I just ordered a new harness off amazon, working soo far, this will be my last harness... Pony up next time for the trucklite LED's

Harness is of decent quality......as stated above, with decent relays I would have had no issues. If you read about the harness, you will notice that most people have had an issue with the relays. Once that problem is corrected, there has not been any further issues. Some people will splice different H4 connectors due to poor quality or poor design.

I just got my Putco harness along with rampage housings, and hella 100/80W bulbs. Before I put them in do you guys advise getting different relays and toss the ones that came with the harness? (ex. like the pilot brand ones from O'reily or wherever?)

You normally mount the relays up top near the battery, so they are easy to change out if they have issues. I'd just wait till an issue occurs before worrying about them.
My issue was a wonky connection at the relay....works now. If anyone wants to get a new relay (I ended up getting new relays just because) Borg Warner makes one that is an acceptable replacement....part # is R4136. Much better lighting now!!
Thanks again for the insight
