Sweet.  Good Job! 
 
Hint.  Put some never sieze on the steering wheel hub (toothed) so future pulling of the wheel is easy.

excellent guide.  There's a spec for current draw (IIRC) that you're supposed to adjust for when playing with the adjusting screw on the back.  This info is listed in the TSM.

I typically use a pencil eraser to clean brass contacts, or even contacts on the back of dash panels, etc. Does a good job. Then, don't touch it with your fingers.............

Billd:
As a ham radio operator and also a short wave radio tinkerer, a product that I have run into for cleaning anything that could carry electricity is called Cramolin R-5 DeOxIt contact cleaner.  Although not very well known, Cramolin R-5 DeOxIt is used in high level electronics applications and in professional radio and TV stations and it is by far the finest product to clean any contact materials that carry electricity.
 
It is made by Caig Laboratories in CA   www.deoxit.com
 
I use it on all connectors and bulbs and anything that could be used to carry electricity.  Cramolin DeOxIt is a nice weapon to have in the old car garage.
 
I ran across this product while cleaning up my old Zenith Trans-Oceanic SW radio a few years back.  The volume control rheostat would make all sorts of "crakle" noises in the speaker when you turned it.  A few shots of DeOxIt and viola... no more crakle and I will tell you that automagically the volume output of the radio increased perhaps 4 fold!
 
I used it on the dimmer rheostat on the AMX and again.. viola.... all of my gauge lights became a bit brighter and the fine tunability of the brightness was enhanced.  Before, they would be off then bing... they would be on and then bing on full...  now there is a nice gradual sweep of intensity.  A miraculous product.
 
One can will probably last you quiet a while.  And I even use it on wire and terminals prior to soldering.  It is not a flux but somehow works.  Wipe it off with a tissue prior to soldering so there is no splat...  Also spray it on any connectors in the car and even on door jam switches and in light sockets.  I would not use it as a food seasoning or on steak or the grill..Wink

Ah, a ham! Cool.
I learned the eraser trick when building computers in the '80s.
It used to be that weird things happened with cards and memory when connections were less than perfect - thermal conditions, etc. and you removed the card or the RAM and burnished the connections - cleaned them with an eraser, brushed them off (not touching them with your fingers) and reinserted and all was fine - usually.
I think it was actually a computer journal or something....
I've used it for years. It's a very mild abrasive.

I'm sure that product is more professional and better for delicate stuff.
But you know, that Rambler mentality keeps poking through! Wink
Had to assume there was a good product for that purpose!
Since I still build and repair computers and other electrical things, it's good to keep in mind.

An electrician turned me on to a product to put on connections in electrical boxes, esp with there's a mix of metals. I've used it on battery posts and light bulbs as well, although I usually use the silicon dielectric stuff on bulb sockets - it's a dream there!

I found a Corvette horn rebuild kit at ZIP Corvette parts https://www.zip-corvette.com/ which is a direct drop in for the Javelin/AMX horns. At least the 1971 horns that I'm working on. There is a basic kit which contains gaskets and rivets for $25 and a deluxe kit which also contains new diaphragms and other parts. I looked into having them rebuilt and it's a $200 endeavor.

FWIW, my primary automotive instructor was (among other things) a long term Porsche / Audi tech, and had deep connections at Ford and a couple other companies.  He said they all told him the pencil eraser trick leaves a residue that can damage contacts over the long term and that something like what 12guage recommends or CRC Contact Cleaner was a far better option.


EDIT: This is about the only thing I'd second guess Bill on though.Big smile
