I've spliced the old connector, and bought a universal horn. No matter what wiring configuration I set up, it will not work, and sometimes blows the fuse under the hood depending on the wiring. There is a factory installed alarm, could this be a problem?
You need to wire a relay to the horn wire first and then run the wire from the relay to the horn. You need to get a single pole relay. go the auto parts store and tell them what you are doing and they will sell you a basic horn relay. The stock horn had a relay attached to it.

"I bypassed the immobilizer circuit only on my alarm module (which is really tedious). Bypassing the whole
module is possible (and little easier), but you will lose the use of the remotes and the ability to arm the alarm.
The alarm module in my '97 900 SETC is located under the carpet, below the driver's power seat switches (a
pain to get at).
If you want to bypass the module completely:
1. Disconnect the battery (make sure you know the radio code-if needed)
2. Unplug the connector from alarm module and remove module from car
3. Install a wire jumper between pin 8 and pin 20 in the connector
4. Install a wire jumper between pin 9 and pin 21 in the connector
5. Install a wire jumper between pin 10 and pin 22 in the connector
6. Wrap securely with electrical tape
If you want to bypass the immobilizer circuit only:
1. Disconnect the battery (make sure you know the radio code-if needed)
2. Unplug the connector from the alarm module
3. Cut the following wires from the back of the connector and splice together as follows (Don't cut the wires too
close to the connector, because someday down the road you may want install a new module, so you'll have to
reverse this process):
4. Cut the wires to pin 8 and pin 20 and splice together w/ wire nut
5. Cut the wires to pin 9 and pin 21 and splice together w/ wire nut
6. Cut the wires to pin 10 and pin 22 and splice together w/ wire nut
7. Secure all with electrical tape
8. Reconnect the connector to the module
Not knowing the details of your problem, please be aware that this may, or may not, solve it. Good luck and let
me know how you make out."
You just diagnosed the electrical short in the alarm system but now the question is where? Check the wiring at the main junctions since you have 2 problems at once. By the way the horn & flashers do work other than using the alarm, Right? If so start at the fuse box & trace the wiring where the alarm is spliced in.
horn relay located on the right side kick panel,you will see a row of relays,if horn relay is okay, more likely your horn control pad has a short inside causing horn button contacts to stick causing horn to keep blowing.
Hello! There is a Hood Switch designed to operate the Alarm If the hood is opened when the car is locked with alarm set...The Hood Switch is affected by heat from the engine plus the ambient temperature...The wire colors on the two pin switch connector are...Black/Pink and Black...Replace the switch OR clip a wire across those two pins which tells the system the switch is permanently closed...If this doesn't work, try disconnecting the connector which leaves the switch permanently open...I believe if you short out the switch the system won't know and the trouble will be removed...Guru...saailer
1Buy a horn kit. Direct replacement kits for the Jeep Grand Cherokee models will have only one horn, but many aftermarket kits consist of two horns.
2Locate the original manufacturer's horn. The horn for the Jeep Grand Cherokee is mounted under the right turn signal behind the front bumper. The easiest way to access it is from underneath the front of your Jeep.
3Disconnect the power connector from the horn, unscrew the mounting bolts with a socket wrench and remove the original horn. If you are installing a factory replacement, you can simply attach the old wiring harness to the new horn and mount it in the original location. However, if you are installing two horns, you will need to find a sturdy location with minimal vibrations.
4Splice the original pair of wires to the two horns according to the instructions for the new horns. The kit should include the connectors that you will need. Generally, you will splice a Y connection to each original wire to produce two pairs of wires that are connected to a new wiring harness. You will then connect each harness to one of the new horns.
5Test the new horns to ensure they work.
*I've done this myself on a few of my Jeeps, these directions are the simplest though, but do not take into account any "issues" . For the simplest fix, i would by a replacement horn (same year and model) from a breakers and install, if you're brave you can buy a cheap one form amazon or ebay.
on passengers side behind tire. disconnect battery, remove two wire connectors on starter, unbolt two starter bolts. New starter sometimes comes with wires attatched, cut old wires leaving lots of excess and splice wires together . Crimp connectors are usually heat shrinks. Be sure to heat them to avaiod moisture from getting into connection.
only one horn sounds when you hit the button. the other horn is for the alarm and door locks etc. im not sure which is which, but have someone push the horn button while checking for power and ground at the harness connector. if power and ground are there, replace the horn. for your own sanity, buy an original equipment horn that just plugs right in, a universal aftermarket requires you to frankenstein your wiring. good luck!
Check the fuses first, the alarm is likely wired in after the fuse for the horn switch on its own fuse. If it is not the fuse it is either the horn switch itself (inside the steering wheel) or the wiring. If the alarm was installed at the factory when the truck was made it is most likely a fuse, then the switch. If the alarm was installed aftermarket it is most likely a fuse, then the wiring where the alarm was spliced into the horn wire, then the switch. Get back to me if this doesn't help.
the jetta has a faulty alarm system from the factory i have been working on one in my shop. the alarm moddule is inside the dash behind the light switch and has a 10 pin connector and a 6 pin connector. this can be bypassed if you disconnect both connectors and jump the two large wire on the 6 pin connectors, these wires operate your starter. the car will start and run but your alarm will no longer be active. the door locks and everthing else will still work. the only issue i am having is the factory radio isn't working because it is controlled by the alarm. but worse case scenario i can use an aftermarket radio if need be.
