How to do the 4 or 6 high mod on an 03-06 full size truck for $3.00

if you have a 99-02 chevy you can do the high 4 for free by grounding the yellow wire on the driver side headlight.....

pretty much the easiest way

sweet. im going to have to try this.

does anyone know if its possible to do a 6 low mod? if so, how does the wiring go for the diodes?

easiest and cheapest mod ever! did it today and it worked just fine. got the diodes from radio shack for like 1.50. thanks!

ok, sorry but maybe i missed something. Why can't the 4 high or 6 high with the diodes be done on a '02? Something different in the fuse panel?

I'm not sure it COULDN'T be done, just that it's even easier to ground the yellow wire. Saves you a buck or two on diodes, too.

Mine's an '03, so I don't know for sure, though.

ok, just looked at my '02 and it doesn't seem to have a seperate relay in the fuse box for the low and high been. the only one i see was labeled "HDLP" so might have to go the cheap route of grounding the yellow wire.

I know this is late but for the guy worried about the inspection, you could easily just take the diodes out before inspection and then just put them back afterwards
