Uprating headlamp loom, need help

Post by Mk2Adam »

hi guys, i'm in the middle of making my own uprated headlamp loom using Steve-o's (clubpolo) guide, and me being a complete idiot with electrics i'm having some trouble with the theory :?

this is the MK3 set up (or atleast this is what i'm guessing its like?)
Image
pretty self explanatory really

now this is steve-o's uprated version...
Image
he's added in two relay boxes, so the trigger feed goes to it's own dedicated relay, then sends it to the lamps. i understand this part too unless someone wants to point out something i've missed.

problem comes because my mk2 lights have a seperate lamp for the dipped and full beam, this is the way the orignal lights are set up on mine...
Image
i don't really know what that connecting box thing does in the middle of the wires, just like two of the boxes like on the end (i'm guessing it's just a easy way for vw to adjust to my kind of lights, just by adding in the 1 bit of wiring?) anyway the wires go into the dipped beam and then every wire is split and goes over to the main beam.

now this is what i'm guessing my uprated system should look like...
Image
so the power goes to the relays, then the individual main and dipped go to their dedicated relays...and then the power goes from each relay to it's respective lamp?

is this the correct set up? do i need to include that connector box from the original set-up? i'm a bit worried as in the original set-up each lamp obviously has 3 wires, earth, feed, and power, so does the relay replace the need for the feed and the power just becomes the trigger?

i'm also a bit confused about the feed, does this handle both the high and low beam? or is it 2 individual wires as i couldn't see 2 seperate wires???

if anyones still awake i could really use some advice as i'm utterly useless at electrics, i honestly don't know why i attempted this???? :lol:

Anyone??? :lol: the main thing thats confusing me is how the mk2 system actually tells it whether to use full beam or dipped as only seems to be the one wire going in? would be greately apreciated if anyone knows? :oops:

without trying to 'p you off' you lost me after the first picture, if i gave you any advice at all you'd probably end up setting fire to your car.

hope you find the info you need and in the meantime i'll ask my mates at work.

Steve-O came to my rescue :D

the wire i have labelled as battery is actually the dipped beam feed so it does have 2 wires to control the 2 funtions, therefore shouldn't have any problems now.

there you go, you guys can all sleep at night again :lol:

i don't totally know what it does tbh lol, i think it just lets an extra couple volts through to the bulbs, and that last 2 volts makes a big difference.

if you have a look on this page, about halfway down hardhitter did some pics of his car with and without the loom (i believe his was a loom from pitstop developments though) whereas my kit is homemade...

hehe, cheers dave, i just about understand it now myself, i made a new diagram and showed it to steve-o (the guy that designed the loom) and he said it was all okay, plus i don't have to alter a thing from the standard kit so i was well happy :D
