Why didn't you just buy a center cluster with a tach in it?

They are expensive ($600) and there was much unresolved debate on this forum as to whether or not it would be a simple swap.

On that topic though - it still boggles my mind how Toyota reasoned that not including a tach in all MT Yarii - while including them with the AT's - was a good decision. So, yeah, I wish mine had come with the tach cluster, but it didn't so I bought one and installed it.

I agree, it looks great. Didn't realize that 3M tape was that good for
that type of installation. Being that my car is new, I am leery of drilling
holes, though if I took my time, I could do it right.

Finally got around to installing my Sunpro tach in my '08 today. Thanks to all of you for your information! Couldn't have done it without this thread.

I used all of the same connections, except that the bottom left wire coming out of the OBD port in my '08 was orange, not blue-green. I think someone mentioned that his '09 was orange as well.

Sorry no pics, but it looks pretty much the same as everyone else's 2 5/8 inch tachs..

I also installed my tach last week using this thread. The only thing I did differently was run the lighting wire to the power wire so the gauge is always backlit.

GnomeBody · 04-28-2009, 04:11 PM

Here's My tach install

I used the instructions on this thread with one change (I hooked the dimmer to the stereo dimmer seeing as the new head unit didnt use it anymore)

I also chose to mount it in the upper glove to try to make it less noticeable. In hind sight, I wish the Tach itsself was a little larger and easyier to read, but hey, I can always get a bigger one later

Here are some pics

The Ground Wire

The Tach signal Wire

The power Wire

Im still a little unsure about how safe it is to be running the power wire from the fuse box like I did I gess I can always change it later too.

Thirty-Nine · 05-28-2009, 01:30 PM

I just received my 3-3/4" Autometer Autogage tach. Let the installation melee begin! :-p

FYI, I found a video on "How to install a tachometer on a Toyota Echo."

Is this similar to installing on a Yaris?

DevilGirl · 08-12-2009, 08:30 PM

I'm trying to understand how to install a tach. I've been attempting to research on here, read through this thread, and find what will be best for me (as I'm sure most of you have seen my different posts on this subject by now).

My question is this, can this be done without drilling holes anywhere in either the dash or other places? I'm sure I can mount the actual tach to the steering column using velcro or a strong doublesided tape. However, I am concerned about the wire routing. Is it possible? Has anyone done something like this?

Truthfully, being as I don't know that much about these kinds of wiring (I've done stereo installs only), the pictures that are here help, but I don't completely understand their orientation to the vehicle itself. Can someone help explain?

I didn't have to drill any holes for mine. If I ever remove it all I would have to do is clean up the 3M tape residue and no one would ever know it was there.

DevilGirl · 08-12-2009, 08:51 PM

So I was just showing this thread to my boyfriend. He doesn't like how in the pictures people have tapped into the OBD port for the rpm readout. As he put it, "it voids the warranty like a sunofabitch." Is there a way to create a OBD plug-in for any regular aftermarket dial tach, so that no wires are actually snipped in this process?

CTScott · 08-12-2009, 09:08 PM

Warranties are voided by tapping wires, unless something is damaged by doing so. The tach signal on the OBDII connector is there for diagnostic purposes.

You could purchase a J1962 male connector to plug into the OBDII port to grab the tach signal, but you'd still need to grab power and an illumination from wires under the dash.

cali yaris · 08-12-2009, 09:53 PM

I've done mods like that and never ever had a problem with dealer servicing, never been questioned about things like tachs etc. This is something for each person to choose what is comfortable for them, and depends somewhat on their relationship with the dealer.

On my Yaris, I know a dealer is never going to see it for servicing again, so my choice with this one is easy.

RedRide · 08-13-2009, 03:11 AM

It's relatively easy to install a tach in the Yaris as all the wire connections that are required can be made in the same general location, right near the steering column.

No drilling, etc is nessary if you use double sided tape to mount the tach.

Personally, I installed a "Speed Hut Revolution tach" (after seeing Altitude's post and pics) and really like it.

I didn't tap the tach wire. I left the end of the signal wire from the tach bare and twisted (tinning it with solder would probably have been better) and just stuck it into the tach wire hole on the OBD connector and put a small drop of glue on it to hold it in place. It can be easily removed.

There are a couple of options for the power and lighting but you'll likely have to tap the lighting unless you want to wire the tach's backlight as always on with the 12v. You can use one of those fuse taps that connect at the fuse box.

fmicle · 08-13-2009, 05:43 AM

Just finished installing my tach, but I haven't connected the illumination wire. I don't know which way to go, the brown wire from the dimmer or the #9 fuse?

I'd like to have dimming for this one, but I guess I can live without it, I prefer connecting it to the fuse even if that doesn't give me dimming. Can anyone confirm?

I connected my tach's illumination wires to the #2 fuse (Panel1).

I also added a "dimmer" that you might be intetresed in.
