not sure

yeah it's a bit confusing

from reading B210 Tachometer i gather:

* RHD and LHD tachometers are different in how they are wired, and differ in how they bolt to the dash

* All North America B210s have the tachometer wiring right there in the dash ... even if it didn't come with a tachometer originally

* For North America there are only two different tachometers: type H62 (1974-1975) and type H72 (1976-1978).

to check the year of your USA B210, check the door tag which has the build date. The underhood ID plate doesn't have the month or year, although the emissions sticker will state the model year

i don't know the difference in the two tachs as both appear to have the same wiring at the back of the tachometer. Three wires: BW signal wire, B ground wire, and a hot wire (R or BG)

These three wires plug into a mini harness with 3 wires on one end, and on the other a 6-pin connector. The harness includes the two lamp sockets that snap into the back of the tachometer

Are there variations of the mini-harness?
Are there variations of the dash harness? dunno

I have checked the VIN and ID number and the car is confirmed to be a 1976 Datsun B210 Coupe (USA). Would that mean that it should have a locking connector? And if the white 8-pin connector is a locking connector, then why would it be so close to the fuse box and not where the tachometer goes, like in the wiki? I just want to make sure that if I buy the tach I mentioned in the first post, that the wiring will be there in my dash.

* early B210s had simple rectangular connectors
* late B210s had locking connectors

going by your GX steering wheel, you have a 1976-1978 USA Coupe?

seem to recall the wiring colors and number of wires differed too

The tech wiki states that "All North America (and perhaps all LHD) B210s have the tachometer wiring right there in the dash". It then gives the image below of the part that connects to the tachometer.


After taking of the dash cluster and looking for an hour, I couldn't find anything similar. The closest things I was an 8 pin connecter like the one in the picture, but white, located near the fuse box. It also didn't have any of the same colors or even same number of wires.




I'm worried that if I buy the tach, this won't be the wiring I need, and I don't have the knowledge necessary to make my own. The tachometer I wanted to buy is on ebay, and It really doesn't look like the same connector to me. Ebay Tachometer

Also, I couldn't find any connector with the right color wires as shown in the wiring diagram from the mechanics manual, which I have attached. Is there something I'm missing? Does the wiring exist in my car like the wiki says? I want confirmation with someone with more knowledge before I purchase anything. Below are a couple more pictures of the wiring around the dash area. I can take better or more specific pictures if need be. Thank you so much for any help you can give.







PS: I know she's looking rough right now but she's a work in progress. One day she'll be good as new.
