A very great DIY. I wish to add tacho to our Waggy, but I'm not that good in handling with electricals.

Live 12V supply was tapped from the acc. socket since my friend wanted it to light up the moment he turns the key. Moreover it was easier this way without splicing / cutting of any wires.

Attachment 1162637
I wonder what that part is (The one behind the 12V socket).

No panels on the dashboard needs to be opened (though we had removed the entire dash in our quest)

How to remove the entire dash? I found many clips, but didn't know which are to be removed.

And since I don't have drilling tools, etc., is it possible to get the tacho installed at MASS?

Thanks,
Sooraj.

Sorry for my back to back posts. Mods, please merge if necessary.

Found an OEM tachometer for the A-star in this link. The image shows that the wire coming out of the tacho is connected to a connector as a whole. Are the individual wires (red, black, blue and yellow) present inside the black surrounding material? Planning to order one. Hoping to get some help.

Thanks,
Sooraj.

Yes. The four wires are present inside the sheath connected to that white connector. Quoting from my DIY Install thread:

The Tachometer comes with 4 wires (Red, Black, Blue and Yellow), the Red is +ve; Black is –ve; Blue is tachometer backlight and Yellow is the RPM/Tacho signal wire.

For the Red wire, I have used a fuse tap cable and connected to a fuse in the fuse box that works only when the ignition is ON. Same as what I have done with the Blue wire that is the backlight one that requires a 12V supply so connected it to the fuse box via another fuse tap cable.

The black wire is crimped using a ring terminal connector to be used as Earthing on any bolt.

The Yellow wire is connected to via a T-tap connector to the brown wire that was separated from the coupler.

You can refer to the thread here for other details.

Thank you so much for your prompt reply. I read your thread, and finally got some idea on how to remove the dashboard.

Do you know what that part is?
The one I've marked in red. Image is taken from vishwaschettri's post.


Thanks,

Looks like a connector ('L' shaped) to connect the positive and negative terminals of the 12V socket which helps in easy removal of the socket if required.

[Tom Sooraj]

Thanks for the steps on how to remove the dashboard. Just tried whether I could remove it or not. I failed twice, but succeeded at the third attempt.



Found the coupler joining the PS module.



Is it required to remove the indicator-wiper housing (behind the steering wheel)?

May I know where can I get that?

Thanks,

Not required.

Salvage yard or any popular MASS in your city (where you have good contacts) can help you get that part.

AFAIK it is a part of the dashboard wiring harness so getting it separately is difficult. I'll check online and shall share the link if I find one.

The part, which I've been asking for, is present behind the 12v socket. Sorry for my ignorance.





And a few more queries:
1. Is the 3rd wire the brown one?

2. Should the parallel feed wire be inserted via the other end of the brown wire?



3. How to connect the wire to the 12v socket?

4. Should heat shrink tube be used compulsorily or just insulation tape is enough?

Thanks,
Sooraj.

Yes. I'm saying that wiring with that connector (in black) is included in the dashboard wiring harness. I don't think that connector (in black) will be available separately for purchase.

You can use a quick splice connector. IIRC that's what I used too.

Use a fuse tap cable from the fuse box. Easier and safer too.

Heat shrink tubing will be better if used and will look neater. In case you don't have that with you, use the insulation tape.

You've used a T-tap connector. Does attaching the wire to the male connector require a crimping tool?

The fuse box in our Waggy is like this:

And a big thanks to you for clarifying my doubts with patience.

Thank you for refreshing my memory. Yes, I had used a T-tap connector.

You'll need the crimping tool to crimp the wire to the connector.

Before you crimp or solder or join two wires, slide in a heat shrink tube first, then join the wires and then slide the heat shrink tube over that 'exposed joint' and heat that tube using a hot air gun (if available) else use a lighter.

The tube will shrink and take that shape protecting the wire and connection.

A fuse tap cable (with two 15A fuses) is to be inserted in the fuse box, right?

I'm sorry but your answer is a bit confusing for me. I saw a youtube video in which the person connected individual wires at each end of the heat shrink tube, crimped them and then heated the tube using a lighter. Is this procedure okay?

Thanks,
Sooraj.

15A and a 10A should be sufficient.

Sorry to complicate it. See this video attached. Hope it helps.

It was not your fault. I just got hold of the word 'crimping' and expected it to be a part of your answer. Now, I understood your point.

And finally, placed an order for the A-star tachometer.

Thanks,
Sooraj.
