Aftermarket wheel horn wiring

Hi all

I am very confuaed trying to fix my horn

I have an omp aftermarket wheel which has a red connector attached to the Hub metal bit and available as spade connector to connet to the horn button
Then the horn has two tabs for spade connectors which are ground and positive

Ground is making contact with a hub using a little latch on the back of the horn button so you don't have to wire it

I have a relay which has direct power and ground from battery, a leg going to horn and a leg to the switch which is plugged to the horn button on the hub

This doesn't work however if I touch the horn red wire previously plugged to wheel positive connector the horn works

What am i doing wrong here?

 

on relay, 

30 to live positive direct feed

 

85 ground direct feed

 

87 to horn

 

86 to back of the hub which is grounded but has no other power going to it

 

horn is then grounded

      I recently got their dbw 74mm throttle body and pedal kit. It is sensational quality especially the wiring harnesses. Unfortunately I can’t answer u about the fitment to stock inlet manifold as I’m going Rahjab Racing forward plenum. Only one thing to be careful of is understand u have to pay gst and import fees if your purchase is over $1,000 in one shipment.

      yeah i agree paint match stops it from standing out so much, oh that's actually really good to know i was wondering if it would help with air flow now actually having an outlet in the bonnet. Will have to focus on ducting into and out of the radiator now to make the most of it.

      I would paint match the whole thing to avoid unwanted attention  I had a similar bonnet, paint matched, on my old R33 GTST, but mine was a fibreglass jobbie made by Blitz in QLD, they work extremely well for radiator efficiency and under bonnet temps

      Does anyone run this kit with factory plenum? Does the adapter and bosch tb fit under factory strut brace? I wanted to get this setup before going forward facing manifold. Thanks

      small update time, after always wanting a "cool" looking bonnet for my car and always struggling to find one for the series 2 that i liked and wasn't an insane amount of money. Saw one i liked on RHDjapan from D-speed in Japan the price was very good for a carbon bonnet so good infact i was a little unsure how much i trusted it, decided to bite the bullet and with the help of jesse streeter in not long at all it was at my door. Once it was delivered i ran in from work and quickly unboxed it and to my surprise the quality was actually pretty good i quickly removed the old bonnet and placed on the new one to test it out and even the fitment wasnt too bad at all. Then decided to paint the little grille in the bonnet black to stop it sticking out so much.   I decided to not mess around with the hood latch and just install some aero catch hood pins, having never installed them before did some YouTube university classes and i was good to go. fair to say it is not a fun job at all from making brackets so the pins sit nicely and actually cutting through the bonnet but also being very scared of cutting the holes too big it took wayyyy longer than i would like to admit but finally got it there. Then it was time for a quick test drive to ensure the latches actually worked and thankfully the bonnet looked very stable. I still think paint matching the bonnet and leaving just the part that sticks up as carbon would help make it all look alot neater as im not sure how i feel about all that carbon on a very fridge white car but will leave it as is and see how i feel with time.
