Hooking up the horn wire on a Momo 8002 steering hub?, Got the right Momo hub (8002) for my '74 914-4 but how to connect the horn button/wire? Options

[Jezibel]

G'day all. Got a question for someone with prior experience or knowledge on how to connect the stock 914-4 steering wheel horn wire to the Momo Steering wheel hub (boss). I'm installing a Momo black 'Tuner' model steering wheel and the 8002 Momo hub/boss is supposed to be correct for replacing the stock wheel assembly/hub, but I'll be damned if I have a clue as to how to connect the positive horn wire so as to make a proper press-to-honk connection, since the Momo 8002 hub/boss does not have a connection I can see for this purpose. I have the correct Porsche horn button for use on the Momo hub/boss (to replace the Momo horn button and of course it has a connection to hook up the (+) wire, but where's the opposite end connection on the hub?!

Sorry of this all seems a bit too sophomoric for belief, but I'm clueless! Everything seems to go together quite smoothly (the new hub, the new wheel, et al) but where's the bloody horn wire connection supposed to come from?) Somewhere along the line, I missed out on that crucial information (and of course, there's no step-by-step instruction that comes with the Momo parts).


This assembly (Momo wheel, hub/boss) came to me from AUTO ATLANTA, so as far as all that goes, smooth sailing....but no horn!? HELP! (IMG:style_emoticons/default/headbang.gif) (IMG:style_emoticons/default/headbang.gif) (IMG:style_emoticons/default/headbang.gif)

PS: Tried YOUTUBE, where I was sure someone had posted a video that covers this item, but NOTHING!. Sorry!

PSS: Incredible how much more the stock Porsche wheel assembly/hub weighs, compared to the featherweight Momo replacement components! Feels like Porsche made the stock unit from solid pig-iron! I mean, yeah, keep the manufacturing cost down...but they could have made it LOTS lighter, IMO!

Thanks in advance. As usual, anyone who supplies the (correct) winning answer to this dilemma wins a hand-made crocheted back tub (and I don't mean a 356, here!).

If you can, please post pictures of what you're working with.

The hot should be the original contact ring with a wire going through the wheel hub that's held on by 3 screws.

Remove that from the stock wheel and it SHOULD be able to be attached to the bottom of the MOMO 8002. I have had clearance issues where the mounting bosses were too tall, so I had to shave some down to avoid the ring from getting jammed against the column face. Should look like this when mounted:

I've only worked with the horn buttons that have two contacts. One is typically labeled for ground, the other is the hot. If not labeled, the one in the middle is usually the hot.

There are two versions of the 8002 hub. One is solid, and one is a cage with a rubber boot around it. The grounding is accomplished differently on each one IIRC. Which one do you have?
