How to do high (4,6,8,10) mods

[HackMcMaster]

Feel free to add info that i missed and i will add it in here
99-02
ground one of the yellow wires going into the green block under the fusebox

VVV the following two mods will make them come on with your parking lamps, so its more of a (#+2)hi/(#)lo
to add fogs
86 on the HL relay connect to 86 on the fog lamp relay

to add drls
87 on the HL relay connect to 87 on the fog lamp relay



03-07C
diode from 85 of the hi-beam relay to 85 of the low beam relay


to add Fog Lamps
connect a second diode to 85 on the fog lamp relay
the other end connect to 85 on the hi-beam relay for it to come on with hi-beams-6hi
or connect to 85 on the low beam relay for the 6hi/4lo

to add DRLs
connect a second diode to 86 on the fog lamp relay
the other end connect to 85 on the hi-beam relay for it to come on with hi-beams-6hi
or connect to 85 on the low beam relay for the 6hi/4lo

the DRLs and fog lamps can be used together as previously directed
the white band on the diode dictates where the power is coming from and where it will not go back to thats why its on the high beam side so the low beams cant feed the high beams back on

if you want to do this under the fusebox
white plug on bottom of the fuse block
pin B9 (Black/White wire) is the connected to Pin 85 on the headlamp hi relay
pin D3 (Pink/White wire) is the connected to Pin 85 on the headlamp low relay
pin B3 (Green/White) is the connected to Pin 85 on the fog light relay

need the DRL pin still

Do you need diodes for them like the 03-up?

 

[HackMcMaster]

i know u do for the DRLs but i dont think so for the fogs, simple solution would be to try it without and see if turnign on your fogs turns on anything else, if u try that let me know so i can update one way or the other

Thanks for the info.

Not sure if it makes a difference but everyone says to use the 1N4004 diodes.

On a NBS hi6 loses control of the fogs alone right? Like I couldn't just run fogs and corners anymore.. lows would have to be on also...?

 

[Bootstrap]

I can run fogs separately

Sounds good to me.. guess I'm going to radio shack after work.

Diodes were super cheap too.

Yes you run fogs alone. Or lows alone. But high beams turn all 6 on. And get the diodes BOO5TED mentioned above.

 

[Wrecktangle]

Done deal, thanks for the help fellas.

it depends, if you hook the fogs up to the high beam they will always come on with the highs, i have mine hooked up to the lows so they always come on with the highs and lows, but when neither hte highs or lows are on i can trigger them by themselves... if my button worked

Ok, that's how I want mine to work. Thanks alot Billy. Thread should be sticky'ed now, gonna save alot of time.
