Hey Guys,
I've recently purchased a new momo steering wheel and an HKB Boss kit (ON-177) which is for HICAS and no airbag as my car does not have any airbags on my R33 GTST Series one (09/1993)
Everything has fitted together perfectly, the black plastic piece at the back of the boss kit fits over the horn plug socket and the Hicas lug attached to the clock spring no problem. My steering column has a white ring with 3 round small lugs that fit into 3 small round holes on the back of the boss kit, and they line up perfectly, which is for cancelling the indicators on wheel turn i believe.
With the stock steering wheel, indicators cancel perfectly, with this new setup they dont. I hear the clicking as the wheel is turned like you normally would hear it, but they just dont cancel. I've fitted and refitted, and checked and rechecked for hours, and nothing looks out of place. i also put the new wheel on, lined everything up, started the car, turned the wheel 90 degrees to the left, then took the steering wheel off and confirmed the white ring and 3 lugs rotated with the wheel exactly where i expected them to be.
I've compared the difference from the back of the original steering wheel to the back of the boss kit, and the only difference i can see is that the holes on the boss kit are about 1mm extra in diameter than the orig. wheel.
Attached are some pics of everything in question, I'm really hoping someone has come across this before as i'm at a loss as to whats causing it.
thanks in advance
