1969 Camaro dealer accessories - tachometer

[abiddle]

When I bought this camaro, the first thing I did was rip out the junky aftermarket tach screwed into the dash panel and the wiring, and threw it in the trash - 15 years ago. As I started purchasing parts to restore, I find it on the 1969 custom features and accessories merchandising booklet.

So now I bought two of these so far on ebay, one with the bowtie and one with GM stamped on the top. Same wiring and very similar except the GM has a slightly blue upper lid. The bowtie one is all black and more shiny casing, and it matches the picture in the 1969 Nova and Camaro accessories book.

Does anyone have this bowtie tach installed, or know where I can find installation instructions? And any ideas which model car the GM stamped tach would be for, so I can get it to the correct car restoration?

Thanks - Andy

According to a prior ebay auction i found this info, of course anything on ebay must be true:
"This is an original Chevrolet accessory tachometer that I believe to be part number 987099 for all 1967 cars. It can be mounted on top of the dash, or on the steering column. It's almost identical to part number 993716 for 1968 through 1969 or 1970 cars. My research shows that part number 987099 had a smooth finish and had the Chevy bowtie, and that part number 993716 had a coarse finish and the GM logo on it. "

There are two tach part numbers. Does anyone agree or disagree with this, or have more information
1. 987099 was introduced in 1967, smooth top bowtie emblem.
2. 993716 was introduced in 1968, pebble grain top with GM stamped. Maybe there are pebble grain with bowtie for this part number, but I haven't seen one. 1969 Dealer accessory booklet shows bowtie but I can't tell if its smooth or pebble grain. (attached a picture I have of the GM one) Notice the top pebble grain is a bit blueish?)

And for completeness, in case anyone in the future years sees this thread and wants the installation instructions, I found them. Attached.

Not sure about the GM one, but made me think any other GM product (olds, pontiac, buick, truck, Canadian products).

I think it will look cool to see that tach back in your car. must be some mounting screws or something left over from when it was installed previously. I am surprised you would have tossed it wether it had the bow tie or GM logo, would have made me think of shelving it for the time being.

The installed tach will definitely give your car an aroma of originality...   since most guys improperly install the in dash unit from another car

Mounted in the original holes with the best parts from both tachs. I went with the bowtie top, since this is what I see in the 1969 accessories booklet. This was the easy part mounting it, now I need to figure out how to wire it to work. For now at least its filling the holes on the dash.

Well should be an easy wiring install, only 4 wires and you have the diagram which shows what would be correct. I am sure you know there is a few different ways to wire it, as far the light and the ground, but the tach wire going to the negative side of the coil is pretty much universal.

From what I see, blue to dash lights,blk to ign.(power when switch is on),orange to coil, white to ground. Hope it works

This accessory is a new one on me. I never have heard or seen this, but like all unique , scarce, and GM stuff, it is cool.

I have seen it on a 68-72 Nova, and maybe an Impala as well. But a nice period correct piece.
I am thinking the design was based on not obstructing the view of he driver, like a round aftermarket one might, and would look more obtrusive.

I remember seeing one on a 68 Chevelle back in the 70,s.

John Hooper's Big Book of Camaro Data, page 57. And I have one of these accessories booklets, see images.

Back page - check out the "Custom Features" stand in the drawing. Sorry, this is just cool. I wonder if this was actually found in show rooms?

The instructions list camaro specific directions, so I assume it was dealer installed. I would still like to know bowtie or GM stamp for my car.

Those instructions look familiar, thanks for saving me a trip downstairs to repost them!

The tach works, although the information it provides is relatively useless. If you can't tell by the sound of the engine that you are pushing the red line, this little guage isn't going to help.

I hooked the wires up with jumpers. Suggestions on where to get wire to match so that I can extend the cut wires?

My first post was Oct 31,2006 asking if anyone had this tach...you are now the only other 69 camaro I have seen with this tach ...mine is the bowtie one

Hi Puress - may I ask what your build date is, and do you have a picture? I'm curious if yours was located to the centerline of the sterring wheel, mine was not. Is it smooth or pebble grain, with the bowtie? And does your ground actually attach to the pedal bracket (punch and drill a hole per the camaro instructions above)?

Thanks!
