Rhd cluster harness

Hey guys I bought a previously built track car that I’m taking on as a time attack project. I pulled the dash out to find the cluster not wired. I only have these 2 blue clips (in picture) and behind the cluster I only have this harness (picture) I also think I’m missing my center clip

All the plugs that go to the back of the cluster are white. Not sure where those blue plugs need to go.

It looks like you have a royal pain there to sort through.

There's some threads with pictures of the various harnesses with what each connector is, you will need to go through that and figure out wiring. Someone hacked up that wiring big time so you're going to have to be methodical and figure out what they did.

What market is the car originally from? What year?

Hmmm, must be different for different markets, two of mine are white, two are black. Pretty sure it was a black and a white 12 pin, a black 10 pin, and a white 8 pin.

its wild because I opened up the whole harness behind the dash and there isn’t one single cut wire

I presume with the past history, heater, etc is deleted, maybe that's why you can't find anything. Other than that, those blue plugs commonly join separate harnesses, instrument to front, or dash to emissions would be likely candidates, also seem to remember a blue one under the steering column. If you get better pics of the connectors, might be able to narrow it down via Au market diagrams.

Zacman is correct, both black and white connectors on the instrument cluster of Japanese cars.

The car was imported from Japan, there is still a blue / yellow connector you speak of mounted under the steering column and another 2 blue ones (in picture) is it possible that I have the wrong cluster harness for the car? Would the correct one possibly have blue connectors to join to the ones on the chassis harness? I’m out of town for the weekend, but when I’m back I’ll take more pictures

Here’s some more picture of the dash harness, it’s a 93. The missing clip on the center of the cluster.. is that suppose to come out of the chassis harness? And the one lone white connector splitting from the left and right connector on the cluster where the helldoes that go? I have no where on the chassis harness that has a matching connector like that, just the two blue connectors…

Okay I figured it out, I have the dash harness which is what’s seen on pictures here.. I’m missing the instrument panel harness (yellow on diagram) does anyone know where I can acquire one or someone who can make one?

I have the same mess going on, but why a Telephone in the trunk ?

Ok as far as I know there is no telephone in the trunk of my 92 RHD JDM FD. However, I do have a fuse in the X-02 box labeled (TEL) , just like that in brackets , bottom left 20 amp fuse. Traced it to the right kick panel , and it runs out through the right sill.

While I am here, I have also traced the yellow wire (single faded pink stripe) from the recall fan control, left side that also ends up going out back same place, right side sill. It's one of many wires on that control box, but what it interconnects with out back ????

Any help on finding the TEL fused circuit function would be great. Thanks

What is your VIN? There were quite a few changes from Version 1 to Version 2, and then to Version 3 in Japan (all are Series 6), and each have their own set of wiring diagrams which all "stack" together. Quite a few of these changes may not be reflected in the North American wiring diagrams either. It's been awhile since I look at the North American diagrams, so I can't say from memory what was changed. Either way, a VIN number would allow me to run a Build Sheet on it which will eliminate all the guesswork so you can get the proper info from the start. Isn't it great that there's people here who can translate Japanese?

Anyway, I just checked the 11/1991 diagram and the 20A TEL (Telephone) fuse is constant power and goes directly to the TEL Adapter on a Brown wire. From there, an oldschool brick cell phone could be wired in. This is the circuit's only use. The Eunos Cosmo has a nearly identical setup in it. These devices usually operated on NTT (Nippon Telephone & Telegraph) service. NTT is actually a cousin to AT&T, having taken over for their post-WWII operations in Japan in 1952. They have a subsidiary service provider in the US, NTT Docomo USA, since 1999.

BMWs in the 90s have a similar setup, such as that from my E38. I'm pretty sure they used Deutsche Telekom as the provider in Germany. I can only guess that the service provider in the US was either AT&T or Voicestream Wireless (later called T-Mobile) at the time.

Helpful to see if you can get the wiring diagram book(s). Usually one or two on ebay for about $100.

The electrical troubleshooting manuals are also worth their weight in bitcoin.

Interesting intel about the TEL circuit. I gonna have to hook up a phone now.

Moshi, moshi!

All long since NLA. Best bet if patient, probably Yahoo for an exact match if nobody has a wrecker locally. Probably have more luck finding complete car harnesses out of a later car nowadays.

There have been a number of complete dashes on YAJ/Buyee lately. Shipping might be impossible. Find one and give the auction number to Jesse Streeter and see if it is something he would do. Shipping would likely be about C$1200.

It may have been touched on already, but two of the plugs for the cluster run off the instrument harness direct, and another two connect to the instrument harness through a subharness (possible the one pictured above)

People often refer to the emissions harness as the engine harness. The emissions harness connects all those pesky solenoids and is usually fried to death.

A curiousity is that the emission harness has a branch that runs back to three or four sensors in the area of the transmission (back-up lights, etc.). On scrap "emissions" harnesses, I have seen, this branch is often cut off, leaving a mystery.

As far as I am aware of, there is no specific diagram for each harness. You are left to puzzle that out on your own (please tell me I am wrong).

We had quite a chat about instrument harnesses, etc., in this thread:

They are calling it the dash harness, but they show a tag saying "30E" which would, in fact, be the instrument harness. Dash harness would be "40". Unless they are in fact both there.

Price is fairly consistant with recent pricing (even for ebay).

You want to google search for F100-67-030E for that particular harness pictured.

If you want to DM me your cars VIN, I could likely look up the number for the exact harness you are puzzling with.

The final version of the parts manual for JDM version one cars shows that that ebay F100-67-030E is from a manual transmission FD with VIN number between 100070-100927 (so made in 1991).

Your short instrument harness F100-67-03ZA seems to have been used in all JDM version one cars, which does not give us a clue which "030" applies to your car. There are about 40 different "030" harnesses listed for the full run of Version ! cars.

I suspect F100-67-030E would have most of what you are looking for. The differences usually correspond to options such as radio, cd player and or sunroof.

F100-67-030E came on cars with neither cd player, base radio or sunroof. (Types S, R, Y and RZ could have come with such components not included.)

Probably save yourself some trouble to just grab that 030E.

The ebay listing says the harness is "new or near new". The condition of the foams certainly would bear that out. It is a rare find indeed.

Agreed. It's kinda silly to proceed without a VIN when one can nail it down to the correct part and eliminate any guessing with the proper information. Vnila4, either post or PM your VIN to either Redbul or myself. Otherwise, this is all an exercise in futility.

It would be good to save the peeled harness as a tool to trace all the wiring around. I am essentially doing that with a scrap emissions harness.
