horn wires and boss kits - oh my

[Dontspankmabitchup]

hey all. been trynna tidy up some sketchy mods so kindly left hidden by the previous owner like Easter eggs inside my baby. since ive had the car ive had no working horn. the steering wheel is after market and the boss kit seems to have no brand name on it at all. as far as i can tell the hicas is hooked up well enough (when i take out the hicas fuse the car's steering goes floaty, so it must be working, right?) but no wires had been fed through the boss kit to to horn button. i must note that the boss kit has quite a solid body so i cant see through it like some of the framed ones. it just seems to to sit over a thin black plastic plate(?) and connects into the box which holds the indicator and wiper stalks.

my two main issues are this... i can not find the horn wire and am struggling to find a straight-forward answer to which colored wire is the horns and where it either comes from or goes to. being a previously molested car, the wiring behind the wheel and in the footwell have seen better days and in some spots it seems wires have been cut and soldered back onto themselves.. ive been tinkiering with the green and red striped wire that has had one end soldered back to either itself or a ground wire, and am starting to think its been hardwired off out of convenience when the boss kit was installed. but if its not the horn wire then im wasting my time. ive tried to look at pics of the column after the wheels been removed to try and find clues of what plugs and wires need my attention, but it all looks different because mine is all covered up by the boss kit which  leads me to my second problem, i cant remove the boss for the life of me. and because i cant get a good look between the kit and the column, i cant tell which parts im supposed to pull and which parts im not. i dont wanna keep trying to tug if the boss kit is hardwired on(if that's a thing) and im also kinda scared that all my pulling and prying might damage that yellow round thing that's exposed when the wheel's off (seen it in pics and have been told its important and not to funk with it)... but since i cant remove or look past my boss kit, im not sure what side of the stalks it's on.. from my perspective it looks like the thin plastic plate between the stalks and the boss kit are apart of the boss kit that needs removing but im pretty sure the boss kit should be solid metal, and all that is plastic stays on the car. the thin plastic plate looks like it wiggles and doest quite sit flush in either direction.

if anyone has any advice on how to identify the horn wire after some mild molestation, or any info on different boss kits that might shine light on mine (hardwired or cheapo brands with strange plastic bits?)  or if someone has any pics of what the column and wires would look like stock so i can work backwards from the molestation. or even if someone has a side on pic of an installed boss kit so i can see what it consists of when attached and what parts should and shouldnt move when trying to remove the boss kit. a wiring diagram would also be helpful.

 sorry about the big write up over something small but i feel like it should be easier than this, and its only being made harder by a stubborn boss kit that cant be moved or looked past. it just looks so very different from other boss kits, it doesn't even appear to have anywhere to feed the wires through unless you cut the clips and feed through the small gap between the boss and thin plastic plate, which is a good solution but dosnt seem like the original intention.

thanks in advance for any help that may come my way. my car is a 93 r33 gts25t s1.

i have poor internet connection and no working camera on my phone so i may be slow to reply but please bare with me, and i'll find a way to take photos and upload them as needed.

Have you pulled the boss kit off? There is a plug in the HICAS hub for the horn. It may just not have been pulled through the boss kit

Can't get the boss kit off. The center nut came of fine but the boss kit has no play at all. Not even a wiggle

i got the boss kit off finally, which has answered some questions and raised some more. the boss kit itself is not plugged into anything at all. the plug on the steering angle sensor is bare. can someone clarify if that plug is for the horn or the hicas? i think i better get a new boss kit that had the plugs and adapters, so if anyone can recommend a good and commonly found brand, i'd be grateful. maybe something i can find at autopro? (im a fair hike from the city)

only other question is about the steering angle sensor. the nissan logo is at 4 oclock and the plug is at 1 oclock. is this acceptable or i or should i straighten it up a bit?

it has been this way since i bought it so maybe that could explain the occasional hicas light and heavy corners. it seems to drive well enough so i dont wanna fix something that aint broke (especially if i can risk f**king it up worse) but if ive been driving it wonky this whole time then my point of reference is probably off.. maybe someone who's driven more skylines would think my steering is funky and i simply havent driven with anything better to notice the difference? i would love to get her mickey mouse if possible so how do approach this. is there any harm in just spinning it around?
