just a nice guy –
Good looking general purpose tachometer. This review might be a little long as I’m also including brief how-to points for my truck. I installed this on my 1990 Chevy C1500 truck. It has a 350 V8 and manual trans but no tach. How can I have fun driving a V8 powered, stick shift truck without a tach?I didn’t need or want a big racer boy tach and this Bosch 2-5/8″ tach is just the right size for column mounting. This Bosch tach comes with the connectors most likely needed for installation except a hose clamp to attach the tach to the steering column. I assume since not every install is going to mount to the column, they leave it up to the installer.Installation was relatively straightforward even though I did take a day or so to test and think out the process I was going to need. I also researched U-tube vids to see where to connect the green sensor wire. Which is the unused white wire coming off the front of the distributor. I drilled a small hole a few inches above where the accelerator cable goes thru the firewall as this area had most room and clearance. A rubber grommet is also included to run the sensor wire thru the firewall. I used fuse taps to connect the power and illumination wires in the fuse panel, which happened to a few inches from the steering column. As I was connecting the power wires, leaving the ground wire for last, I noticed the tach had power. I figure since the tach is now attached to the steering column which is metal, it became grounded. I still connected the tach ground wire anyway.The photo of the dash with the tach looks like the view of one of the factory gauges behind it is blocked but it’s not. The pic is a close up. When I’m actually sitting behind the wheel, I’m up high enough to see the gauge.Like some other reviewers have noted, the tach light is pretty dim. It is adequate for general night time driving but I may upgrade the light later. One other thing- the rev pointer is on the OUTSIDE of the gauge face! This part wasn’t clear to me in the instructions. I had been trying to twist the whole bezel like twisting a empty beer can to move the pointer when my fingers accidentally touched the pointer and it moved. Well duh! Probably everyone else in the world knows this except me but just in case there’s others, that’s how to reposition the pointer. You’re welcome!I like this tach, it looks good and fits in with the dash and seems to function well.I’m sure most people will be satisfied too.

Works like a charm. Seems accurate and I like that it’s a bit smaller than the huge, “in your face,” ones everyone else seems to have.

The gauge looks good, but the connections had a ground, an I, and an s. The “S” said connect to sensor, what sensor. Crappy instructions. I even found the VDO installation instructions on line, and none of them matched the physical descriptions of the gauge (voltage meter). I think this may be a cheap knock-off part.

Love the clean and simple look, the light is dim so I’ll have to find a better bulb.

This product is awesome has a light to illuminate it at night really accurate if your looking to adding a tach to your car don’t think twice Bosch is a great tool brand and they don’t let you don’t with there automotive products either I installed in a 1988 toyota pickup

Good enough and easy install into my 84 Dodge D150 but the backlight doesn’t work. I’m not sure if the bulb is broken or if something is defective.

This is a perfect tach for someone who just needs the bare minimum. I installed this in a 1990 gmc sierra it was super easy it works perfect. This is probably not what you would want for the race track or drag strip. I was having idling issues and I just needed to know where I stood, it was perfect for that and I decided to install it permanently. I love that it’s not super bright at night and it’s simple, I didn’t need a huge tach with super bright shift light I just needed a old school tach, it is accurate as far as I can tell.

Above average quality. Sturdy and fast response, I would recommend this purchase if a compact size is needed. Good stuff.
