I just got a new boss to fit (genuine momo without hicas/cruise control support).

I have removed steering wheel and the black unit behind it that has the sensors on for hicas etc.

 

Is it safe to then fit the momo hub - it seems to bolt on very securely but the horn does not work - the ring on the back of the momo doesnt touch anything - I had to remove the enclosed unit (hicas sensor - im presuming) to fit the momo.

 

Should I strip down the hicas control unit (the black bit behind the steering wheel) to try and join that to the momo for horn support?

 

either way what do I do with the black hicas bit with the wires? do I just cut the wires? I disabled hicas a while ago (well JD did by joining 2 wires under bonnet - thus disabling rear hicas).

 

I cant get any pics till tomorrow so im hoping Ive explained it ok. Please advise me if poss.

lol...Dont know if its safe or not but ive done this to mine :D

I have a HICAS eliminator fitted so theres no problems here as it cannot affect anything but if you havnt got one i wouldnt like to say.

Theres always gonna be a difference in hubs so this might not work on yours but I will post up the pictures if i can find them 4 ya ;)

Basically i took the black plastic round hicas unit apart and used the original contact pads straight onto my horn conductive ring :eek:

I have piccys that show all ;)

Ultimately you should get the proper boss and so forth but this is how to bodge it :smw:

 

piccys to follow

sound matey - get em posted :)

I'll eventually get a hicas brace bar on the rear but for now im happy.

Im more concerned over what to do with the wires and the big plastic ring thing :)

 

Its a genuine momo for a 300zx.

Ok...here goes

You have to make several minor modifications along the way one of which is fileing flat the screw head that holds the spring-contact pad in the hicas unit otherwise this will scrape and make an annoying noise :headvswal .

This is my hub adaptor :-

This is what the spring-contacts look like inside the dismantled HICAS unit :-

I had an extra disc come with my hub.

Its plastic one side with a conductive plate on the other and there are two small metal pins that fit into the hub/boss that will turn the plastic disc which inturn make the horn contact and also the pins will turn the indicators off like it should do.

I used this into the original hicas unit and this red wire will go to the horn button on your steering wheel/boss:-

The yellow wire coming from your hicas plug (tape up the others) is for the horn and needs to be reconnected on the terminal shown once you have dismantled and rebuilt the unit...lol...shat picture sorry :rolleyes: :-

This is the earth wire onto the hub inside which also goes to the horn button on the steering wheel/boss:-

Its been working well for me

The hicas unit comes apart by pressing or pulling the little plastic tags on it...(i cant rember)

Remember...keep all parts then you can refit it if you ever need to ;)

Although its been working well for me :nana2:

 

Before someone posts up and says...

"you want a proper hub adaptor mate"...lol

Yes it does help...

BUT...

It aint fookin cheap

and this mod is free :tongue:
