Hi, I'm new to wiring. I have a 2000 f150 and I was wondering what the BLACK/ pink wire is that runs into the ignition cylinder lock. I was also wondering how to pull a wire out of its connecter such as the horn wire out of the brown 6 pin connecter becasue it seems to be stuck.

You can always cut the wire and reconnect later. You may have to wire up a momentary push button separately to use horn. The trick to pull it out is it should have a release like on relay harnesses. If you have a small flat precision screwdriver you might be able to push the release just enough to pull it out of harness.

The wire I'm test'n isn't doin' what it's supposed to be doin'... I am so glad I printed that tech sheet, with the wrong info.
Do it right the first time... or I might have to fix it for ya

im wiring up some extra horns to my truck and i am using a relay so i can either use my stock horn at one time or my new horns. The problem is is that when my switch is on which sends power to the relay, and i press my horn button, nothing happens, but when have my toggle switch off the stock horn blows when the horn button is pressed. I think I have figured it out to be that there is no power leaving prong 87 which powers my new horns. Please help.

If I had to guess, I would say that you have power going to 87A instead of 30. And you have your stock horn to 30 instead of 87A. 30 is the common terminal, at rest 30 is connected to 87A, when the relay is energized it connects terminal 30 to 87. Power has to be connected to 30 for your application.

Im trying to wire up my air horns so I can use my horn button for either my stock horn or my air horns. I have a led toggle switch which receives power from the battery. From there i have it wired to pin 86. Ground is wired to pin 85. Pin 87 goes to solenoid for air horns which is also grounded. I cut my horn wire from stock horn and have horn button to pin 30 and other side of wire which runs to stock horns to pin 87a. The problem is is that when the led toggle switch is off the stock horn works which is a good thing but when the toggle switch is on the air horns don't sound. I hit my horn button but nothing happens. I did find out though that if i connect pin 86 which receives power from toggle switch and pin 87 which goes to solenoid the air horns sound off continually. Please help and thank you.

Anyone have any ideas? Have i wired it wrong?

do you guys think it is a problem with the relay or wire i have running to the solenoid because when i switched around the wires between 87a and 87 the stock horn now went when the toggle switch was on and nothing happened when the toggle switch was in the off position.

The problem here is that your solenoid is going directly to the horn when the toggle switch is pushed, and your horn switch isn't designed for that much current.
You want to do it with 2 relays, wired like the following diagram.
EDIT: Ok, I screwed that up slightly. 85 on the LEFT relay should go to your toggle switch; the other side of your toggle switch should go to the horn switch wire. ------------- C Renner's Auto Electronix

What's the difference between the input and output to the air horn solenoid. I only have two wires for the air solenoid, one which is from the relay to the solenoid and the other one is the ground for the soleniod which is grounded right at the solenoid. Im confused about pin 87 and 30 on the second relay

Ok that answers one question - you're switching the power to the positive side of the solenoid. I used the terms "input" and "output" with respect to the relay - they don't both get connected directly to the solenoid, though obviously they both are part of the circuit for it. The input has to get constant fused 12V...if you had been switching the negative side of the solenoid, the input to relay 2 would get ground, and your positive wire to the solenoid would go directly to the battery or other 12 volt source. Does that explain it? ------------- C Renner's Auto Electronix

if you want to do it another way i did this on y coupe ran 3 wires from the horn back to under the dash to a 3 way togle ( 1 hot from horn button 2 feed to stock horn 3 feed for air horns ) this worked quite well so the cops could not give me a noise ticket for air horns
