R33 Horn wiring

96 R33 gtst S2 

G'day could someone please shed some light on how to wire up the 33 horn on an aftermarket wheel 

I have searched absolutely everywhere and have found nothing helpful at all I understand how to connect it but I can't seem to get any response from any of the wires 

For starters the horns work when I put a feed directly through them.

i have replaced the relay

i have changed the fuse to rule that out also and I have tried testing different wires and earthing wires out which i understand the horn works when earth contact is made 

I have 2 wires on a block connector which I know are for airbags then I have 3 wires which have been cut being blue red and yellow (photos below) and I have tried multiple connections and I can't get anything out of it..

 

i have the whole column apart and I can see the wires that would run through to the factory wheel but Im having a real crap time 

can somebody point me in the right direction

Horn works all the time, So ground each wire individually with the car off. Horn should go off when the wire is grounded.

If it doesn't, you may have a wiring issue (if you have already checked the fuse and the relay)

I have a wiring diagram for it but cant upload images at the moment for some reason

    • A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always! 
    • Yeah mate, never miss it.
    • Any going to watch World Time Attack at SMSP this year?
    • Appreciate the correction on the "ground", that will make a huge difference to looking at this. That makes complete sense about AF70/AF71 which is what I had come down to being the issue, one of these. I'll have another look in the ignition wiring when I get a chance next week. I'll also make up a jumper wire for running that AF73 test.  ECU is fine, relay itself is fine, pump harness is fine and the pump itself is fine. I am going to upgrade the Walbro 255 anyway with a DW300 I have since I need to replace the fuel sender and I'm going to upgrade the FPR with my chasebays kit ready for new plenum/injectors/dbw, but I'll get this working first. That's why this is so frustrating.
