I know this is not recomended, but how many of you are running upgraded wattage bulbs without the harness? How long have you been doing this for?

Thanks

 

If you are thinking about putting any light with a higher wattage then stock you are going to fry your socket. sure there are people doing it and they think its ok since it hasent given them any problems, i have done it mylsef, but its a very slow process and over time it will burn up your socket, you wont even notice until it starts to flicker or suddenly go on and off, you can jiggle it and it will work for about another month until its completly fried and you loose the socket and bulb, if you run highwer wattage bulbs get a APC upgraded headlight harness.

 

I did it for 6 months before the stock harness fried, two days before I got the harness. . . I put in the harness and it failed after a month, connections just failed for some reason or another. So I just got Piaas. . .

 

50 bucks...buy a new harness and save yourself the troubles...people post all the time that they've been running fine...next thing you know they post about where to get a harness or how to install it or something because theirs finally fried...

 

I've had my 80/100W green headlights in for atleast 4 months now and no problems. Who knows maybe I should just break down and buy the harness, but I'll most likely be a fool and wait for them to burn out...

 

when it fries what is it that you have to change the whole harness or just the bulbs.

 

the whole harness...sometimes you can get lucky and only need to replace the socket

 

i was running with apc 80/100 super whites for like 2 months and then decided to buy the apc super harness...mainly cause i was searching through so many posts and read that they were gonna burn eventually...i bought mine at www.hotpartz.com ... i forgot how much but they i got mine the next day...

 

I have for about the past week. I am waiting on the harness to get here. However, I could swear they are getting dimmer....

It's seems that a lot of the guys getting them recently have had connector and relays go bad. Us guys that got the harness a while back, don't seem to have problems. I think that APC is skimping on parts and quality to meet the high demand.

 

On my 4th gen max the harness burned out 2 times. After using the 80/100 bulbs. Eventually I made one from ford truck light harness "they are really heavy duty wire" and used some relays and powered everything from the battery. The total for the parts was about $ 20. Did not have any problems after the fix.

 

do you have anymore information about how you did that? could you post a list of parts and instructions as I'm very interested in doing this.

 

I used 10 Ga power wire from the battery. A total of four 12v relays, This enables the factory fuses to operate properly. I mounted one relay pack near each headlight. Use a volt meter and label each wire from the original nissan harness, (1)high, (2)low, (3)ground. The relays have to be wired for positive trip. The relays will have terminals 85,87,87a,30,86. Only use 4 of the five. 87a is not used. The negative wire on the factory harness will not be used. The ford harness that I used came from a salvage yard on an 92-96 F-150. They cost around $2. Be shure to fuse the main power wire at the battery. I used 2 waterproof fuse holders and 2 30 amp fuses. I placed the 2 relays together and taped them back to back so that all the wiring could be simplified. The ford 9004 harness ground wire should be taken to the ground shared by the relays, Locate a clean bolt on the body of the car and that should do fine. Look at the attached diagram and hopefully it will explain better. The diagram applies to one side of the car only. This only took me about 30 minutes to wire up and install, it may not be as easy as the 55 dollar harness, but it was over half the price and all I lost was about 30 minutes time.

 

Oops the diagram is too big! E-mail me and I will sent out.

 

i have been using 85w/100w H4 bulbs and have not had a problem whatsoever and i drive around with the lights on almost all the time... even during day time... i just keep the switch in the on position...

 

yup...i agree totally...ive had 2 bad relays sent to me...i finally just went to a parts shop and bought decent ones...i think you hit the nail on the head as to why they are coming out bad...
