4 High Mod

brandon_guzzo · February 4, 2011

Yes I have used the search function and I know how to do the 4 high mod for my 2000 silverado. But instead of pulling the fuse box and cutting the wires, can I tap into the yellow wire on each headlight before the connector and ground it. Instead of cutting and soldering I was just wondering will the wire taps work?

Thanks

Funny you say that, that's exactly how i did mine some t-taps and a piece of wire plus a connector and you got it.

Perfect I will be doing this tomorrow night. Thanks

4 high mod? what is this? or what should i search for? i either get no search results or tons of 4x4 threads to sift through...

EDIT - is a headlight mod?

brandon_guzzo · February 4, 2011

Yep it is a headlight mod. It will keep the low beams on while the high beams are on.For 99-02 you just need to tap into the yellow wire on each headlight and ground it. For 03-06 there is a different method however, it involves a diode in the fuse box.

03-06 mod with diode..

Anyone have a picture of what this looks like on the truck when completed? Im looking for what the fuse box looks like, not the headlights.

Also, what kind of diode do I need, and what a common place to get it?

i would love to do this but what about inspection time???? you think theyd let it pass? im in PA

brandon_guzzo · February 5, 2011

I believe it is a 3 amp 50 volt diode. And here is a picture form another site. Also I think you would be fine with inspection considering most new GM vehicles operate like this from factory.

do i actually fully cut off the wire or just run a ground wire off of it? sounds easy enough

brandon_guzzo · February 5, 2011

I did NOT cut the wire I used the T taps and crimped into the wire to ground it. There is no need to cut it.

Georgebaumann · February 5, 2011

alright sounds good im probably gonna attempt it when i get off tonight

Just did the mod to my truck and i really like it. makes the high beams a whole lot brighter. now im debating hooking up my offora lights to the high beams. would i be able to do that by just rigging it up to the hot wires without blowing the fuse?
