What color and where is the horn wire located..


i know its under the dash but i have no idea what color and cant find that sucker

 

the horn is over by the passenger headlight.

 

right but a wire runs up under the dash..id prefer to tap into that instead of running a wire from the grille area in the truck to the cd player area

 

if you had an 03 i could tell ya, but i dont have an 04 wiring diagrams...

 

gay!! haha

i called nick and he said where to find it but man i looked forever and didnt find it..

so im waitin for bob to pop in..i can figure it out tomorrow from a buddy of mine but i wanna get it done tonight

 

well 04s are wired different than a 01-03... so i would imagine where nick told you is on a 01-03

 

yea under the dash and green he thought..i checked ever freakin green wire under there haha..so yea id say so..

 

Evan what are you trying to do exactly??? Yout dont wanna tap in at the steering wheel area because that wire you are looking for also is used for the cruise and airbag. Its the Yellow/Light Green wire over at the smart junction block in the brown connector. That wire is the output from the horn relay to the horns, when the relay closed you will have 12 volts on that wire.

 

well i want it so i can put a switch on it..so i can honk my steering wheel and stock horn honks..then flip the switch and trains honk..

i got a 2 sided switch

 

If thats the case then you would want to hook the switch up to either supply voltage to the horns or supply voltage to your train horn relay that goes to the solenoid, does that make sense?

 

hmm i think so...my buddy has it all figured out and another guy already did this so im going by what he said and i think thats what it is.

anywho

bump for that wire color@!@

 

as per direct techs.com

Horn Trigger yellow/lt green to dk. blue switch or SJB small black plug pin 18

 

we have a switch like that in our fire trucks.....center button works as a regular horn with the switch in one position; then center button works as an air horn with the switch in the other position.....i think th switch has to be a SPDT switch, but i could be wrong...

 

what the heck is a SPDT swtich


thanks dan o..i had my buddy tell me the word for word of what you just said..

but i still ran into problems so im waiting for another friend to get home which is like my personal bob he will get it all figured out

 

single pole double throw....

 

aka 2 way toggle switch..

ive got one of those

 

yet the more i think about it, the more i believe it will have to be a DPDT (double pole, double throw) switch.........a ON/OFF/ON switch...

 

then you could have it setup like this:

Regular Horn/No Horn at all/Air Horn......

 

riiight but what im runnin in to is ive got my valve wired up wrong as in grounded all the time and power when the button is pushed..it needs to be the other way cuz the stock horn is power all the time needs a ground to honk..

 

i was thinking this would be your issue since bill said it was hot all the time.

 

you can still wire the switch up for it to be ground activated by the stock horn button (grounded).....your control wire going to your valve would be hot all the time with a broken ground.....the airbag being pushed in would give it a ground and make them honk...

 

well i ran out of time..i needed to get his done before the meet tomorrow

so what i did was ran a wire with a fuse from the valve button the horn..i have no stock horn but it honks with it and ive also got a little secret weapon ill get a vid probbaly tomorrow of it..

 

i was thinking about doing the same thing, i just unhooked my stock horn haha.

 

I was..well i am going to..everythin is fused..the valve doesnt draw that much anyways..but as of now my stock horn is gone..and ran to the valve..which is also fused..

i am gunna redo it once i get back from the meet tomorrow i just wanted to get it working for tomorrow
