The G/O wire should not have a ground on it unless the horn was pressed, a short in the wire or the alarm was responsible. Easiest thing to do would be to disconnect the alarm unit which is next to the passenger speaker/amplifier unit to see if that's the cause.

infernoman

my apologies the 2 back horns are going off and the b/r wire to the horn infront of the coolant overflow jug is not

infernoman

and i grounded the g/o wire myself to see if the horn would sound w/ no key

And what was the result?

infernoman

the horn sounded. also the beeping from the cpu was the door dinger just it was very very quiet
EDIT: also disconnect the alarm unit and horn is still sounding w/ key to on

The beeping sound also occurs when the key is to on and the seatbelts are not fastened.

And what happens when the Room fuse is pulled? Does this affect the faint beeping? If it doesn't alter it then pull both the Room and Meter fuse as both power the warning unit inside the CPU and see if this stops the beep that you hear.

And w/respect to the horn w/key to on pull the Stop fuse and this should cut the horn sound. Then place the fuse back in and see if the horn sounds off or stays quiet.

EDIT: And what is the batteries voltage strength at? 12 volts or what?

infernoman

now that you say that the seatbelt light seems to be flashing w/ no key in ignition. when i remove just the room fuse the beeping from the cpu and the seatbelt light flashing stops also removed the meter fuse and horn is still on EDIT: also the battery voltage is at 12 volts and 10 while cranking still have a strong battery and a charger with boost right here incase. battery has been on slow charge since last night.

infernoman

now the horn on the passenger side has stopped working the hi horn i beleive and the low is still working also when i remove the stop fuse the horn does not stop

When I did my swap the wiring diagram that hailers had was wrong
I used a multimeter to track down my temp wire to my
Harness at the ecu plug. Same with my pressure guage
This seemed to work for me. Spent several days trying it the way
You r doing it. Did the same swap as you except I have a 88 vert

There are actually two G/W wires in the large CPU plug. The one that powers the horn relay should be located next to the G/O wire. If the Stop fuse is pulled does this G/W wire lose power or not.

And how about connecting the seatbelts, replace the Room fuse, and w/key to on see if the fainting beep returns or not. You should probably disconnect the horns to hear this.

infernoman

alright the g/w wire closest to the g/o wire has constant 12v w/ no key. with the stop fuse pulled this wire does NOT have a 12v constant BUT the horn is still engaged w/ key to on position

infernoman

seatbelts plugged in and room and meter fuse replaced faint beeping is still there seatbelt light is also still on when doors are closed and w/ no key but the beeping stops when the door closes so it must be the reminder.
EDIT when i removed the stop fuse earlier it turned off the high horn on the passenger side. now when i remove the fuse neither of them stop. w/ key to on position

infernoman

decided id pull the two leading plugs and it seems that neither of them are getting fuel to them, seemed like they had a bit, but even when i turned the car over spark plugs out and egi fuse still in it wasnt breathing out heavy fuel fumes

In a normal sense this is not possible. The possibilities for the horn to soud w/o the Stop fuse is there is an additional alarm system providing voltage to the horns or there is voltage finding its way to the Horn Relay from another source w/key to on. In a normal sense the Stop fuse does this, but apparently another fuse w/key to on is passing its voltage to the Horn Relay and namely the G/W wire. I would pull the IG2 and IG2 fuses one by one w/key to on when the horn is sounding and see which one kills the horn sound. The row w/the Engine fuse are the IG1 fuses and the row below these are the IG2 fuses.

Can't remember if you checked the Engine fuse or not.

infernoman

well ive come to the conclusion that i have no fuel getting to the engine. now i just need to figure out why and if my injectors are even trying to fire. is it possible that a line may have crossed that i cut and caused it to short the ecu under the passenger carpet?

infernoman

have the clear caps from both of the egi fuses off and they both seem to be okay no breaks just slight corrosion

infernoman

the engine fuse 15a is giving the horn power when i pull the 15a w/ key to on position horn stops

infernoman

the headlight switch on the dash on the left the one that just controls the motor. it also sets off my horn if you press it.

Oh my aching head! This might not help, but if the car has remote mirrors or stereo do these items work w/key to ACC as they should or does the key need to be in the on position for them to operate?

infernoman

All stock stereo an no power mirrors. I have power to the radio with the key to acc

satch

Do you happen to have power to the radio w/no key by chance? And if you try to start the car does the radio cut out as it should or does it continue to work. And if the wipers work do they stop briefly w/key to start or do they continue to work. Wondering if the ignition switch has a couple of two wire plugs mixed up or not.

infernoman

Well I've left the shop now I'll be back early morning yet again. Thank you for taking your time out of your day to help me do this. And considering im not getting fuel to rotors should I try wiring the pump straight to the battery. I have spark and I guess I should start with the no start if I can't figure out the horn problem

infernoman

I had a friend who was out at the shop late and asked him to do a couple of things for me. The wipers and radio turn off intermittently while starting the car. Also getting him the make sure the fuel pump is properly working and If not wiring it straight to the battery

infernoman

Also the radio does not work w/ no key
