UPDATED*
my fault i did this thread at like 3 in the morning anyway my car is an 1990 240sx hatch that has 200m autopal e-code(euro spec?) conversion head lights housing kit (using h4 bulbs which came standard forgot the watts waiting for money for some cibies or hella) i readed some where that if you where to use higher h4 bulbs for a more brighter light output you'll need to upgrade the harness to prevent from FAIL haha or maybe death of your car anyways the bulb im planning on using are 90/100w h4 lights btw i would also need to attach a fuse case for them also

so i was wondering which guage yah guys would recommed to make it safe also what fuse to use . I also need a pic of the wiring of what to cut and what not

or should i just skip all this crap i see if they have some bright fog light somewhere

p.s doing this crap at 3-4 in the morn again 3-4 more hours before i go to work damn i need some sleepp....

first what car u have would be helpful. second i dont believe theres an upgrade harness so what u can do is diy and use higher gauge wires. I dont understand y u need to upgrade the harness because replacements SHOULDNT cause any problems like this and if they did the manufacturer would offer harness replacements. Did u replace the whole headlight housing or just the bulb? If anything, go to radio shack, move up in gauge level from the standard 8/10 guage wire? (correct me if im wrong) to the next one (lower number = bigger wire) and u should be fine. Im just worried about ur fuses though....

Wait...WHAT??? What the fuck does upgrading your headlight harness got anything to do with you blinding people?!?! You're changing a fucking bulb to a higher wattage bulb, its not gonna change or move your cut offs.

The only reason you need to change wires is due to the higher wattage bulbs. Stock wires are too skinny and have a potential to burn up/melt/catch on fire due to the extra power draw and the bulbs running hotter.

Its not rocket science like already stated, buy some crimper, some bigger gauge wire, crimp connectors (better yet, learn to solder) and atleast redo the wires from the wiring plug to the headlight plug.

Sil-Abc..you are correct. Wire gets bigger as the gauge number gets lower.

Relays. Simple, add a relay per bulb. Or, keep the OE wattage bulbs, you're not gaining very much by going higher wattage if the housing isn't designed for it.

Yeah what car..is it a nissan or and audi/vw. I know I've seem that term e-code on vw sites. But that could refer european guidelines? Pretty sure they have plug and play harnesses on ebay. just match to your bulb size...h4, h3, 9005 etc.

Only suggestion I cna think of

[projectRDM]

I'd really like to see a picture of what all that ^ comes with. If there's no relays, fuses, and a lead to the battery it's useless.

Catz Zeta ftw.

[s13pignose]

Aw crap i forgot about theno ebay links...don't ban me lol. My bad..just trying to help. But yea it doesn't have relays. There was an apc harness that included all that lol...but then again I'm not the biggest fan of apc nor do I like to promote them lol

See, that's stupid. How can it handle higher current without relays? If you're just stepping the wire up a gauge, the smaller gauge is still the weak point. I hope people aren't buying that shit.

[s13pignose]

I dunno lol..I didn't. Believe it was14 gauge wire heat resistant plastic...the ebay one that is

[khmer1]

i wonna see if there's a good harness that already made like this that people might recommend and agree that is good

hmm seems like the second one s13 pignose posted looks good i might get that...but i dont know about it unless some one has use it before

also i seen this on ebay Matrix Upgrade Wire Harness H4 4 Lamps - 01-133 (looks like it come with the fuses and stuff waiting on a response from the seller)but yah have to search it since pignose said there a rule or something with posting ebay links right?
