9004 head light kit Oct 23, 2008

I Had problems thith the first kit but the scond kit was the the best I found out how to move the tabs and make the hi and ground be where they are intended. Now I can run the bulbs that i wanted to run and they are bright. I had to replace this kit because the low beam was only operating at 9.10 volts not 14.19 like i wanted and like the stock system that operated at 14.19 but not strong to hold the hi amps/watt.
harness quality Feb 06, 2011
By cheapskate The company that makes this harness is Putco. The harness contained a bad crimp at one relay that took a few hours to find and fix by soldering. Once fixed, it worked well.
The company that sold me the harness is eautoworks. They still advertise that it works for both 9004 and 9007 bulbs which is only true if you move the contacts in all three of the connectors. They worked hard to help solve this after they were informed by Putco of their error (they didn't initially believe me) but I can't see why they still advertise it as fitting both bulb types especially when Putco makes a specific harness for each type of bulb.
Good harness, Terrible relays. Nov 30, 2010
By Brandon So the headlight harness does not look like the one pictured but does look like the one on their website. The harness is good itself the connectors are of nice quality the gauge of the wires are good and everything is solid and not flimsly.
However the relays that come with this thing are very cheap plastic stuff that weigh less than a penny. I had problems with the headlights lighting up on hi/low on both sides. I cut out the relays the harness it came with and installed some good quality relays.
