I would usually post this in the electrical section, but it doesn't get viewed as much as this section does. I just installed a set of jdm gauges, everything plugged right in; however, now my lights for the a/c, radio controls, hazard light button, and steering wheel controls don't work. I have done some searching to no avail, but I do have a little help if we have any electrical engineers on the forum. I have the service manual from the usdm fit.

Sorry for the size, I wanted you to be able to read it. Down in the bottom right it says the red wire is for illumination of all the things I mentioned. (and I believe the 1 means pin 1, but I don't really know how to read these fully). Anyone know what I would need to do to get that to work again? Anyone have this same page for a jdm fit? Any help would be great! Thanks!

 

Finally installed em eh? Hope you get this figured out man. I just gave up and lived with it sadly..

 

Yep, took 3 minutes. Fastest install ever!

 

98 views and no one else knows how to read a circuit diagram either? Bummer

 

As i read it, the 1 means pin 1 on the cluster and is carried on the red wire in the harness/plug. The diagram shows that basically the illumination brightness control is a mosfet to ground. I'm not sure if its working as a switch or a resistor (probably depends on the illumination brightness dimmer switch position), but either way, the new gauge cluster isn't doing that.

I assume you've run pin 1 on the 32p connector to ground to verify there's no problem with the wiring? I'd be surprised if there were, but its worth being sure, as its easy to do. (pg 22-255)

Either way, the equivalent page from the JDM book is really what you need.

 

In theory, you could probably figure out a way to bypass the control gauge cluster and just tie the red to ground either directly or through a resistor to get it at the preferred level of brightness, but you'd want a switched ground so that you don't drain the battery. That's up to you to find though, there doesn't appear to be one on the other wires coming into the cluster.

 

i'm just glad you can read it! i wasn't totally sure what i was looking at. i tried pm'ing jdm dave to see if he has the jdm manual. i'll keep my fingers crossed! thanks again for the help!

 

Does the jdm cluster have actual pins in all 32 possible pin spots?

 

I will have to take it back out to look. I know on the usdm, they don't use many of the top pins (1-16).

 

You guys with the red JDM cluster mod.

There should be a JDM wiring diagram in the esm? I'll double check it, I was reading some if it this week and as a side note, there is a way to retain the MM & odo settings but only the dealer can do it with the HDS.

 

The JDM cluster doesn't have a MM. And the Odometer isn't being retained but re-written. Now if only we could get our hands on the HDS.

J, I should have sent you an ESM disc with the cluster.. I think it'll be a pin swap if it's fixable, but not 100% positive on that.

If worst comes to worst you could just take your headunit apart and change the color and on the buttons too. Then it won't be as bright and they'll match!

 

You have the jdm esm, or is there just one? You can just send it down with the headlights. Ha.

 

Jamy you're right... re-written not retain. as for the HDS... working on it.

@jnesselroad... I think there's only one. The one Jamy's referring to has the LHD/RHD diagrams (not like I know how to read them).

 

They already went. Lol Apparently headlights with black trim that don't fog up are a hot commodity on this forum.

I can send you an ESM anyways though if you want it. It's a "one disc covers all" I'm pretty sure.

Sorry slightly OCD lol.

HDS? For reals? How much?

 

LOL... its all good I'm a little OCD too... as for the HDS, well I won't be able to buy it but possibly have unlimited access... working on it thru a few different service guys/managers.
I'd be happy with the TPMS solution (might still try the ATEQ). Side note; about to order the pulsar, thanks for the idea (been wanting that since I saw the Civic SI LED module). ---> 43 LED Brake Light Pad!! - 8th Generation Honda Civic Forum

GL with the gauges, post up any results/info. Always wanted this mod. I'm thinking it might be a relatively simple re-pin as well. What was the issue with de-soldering the old LED's and replacing with new red LED's? Forgot why that wasn't feasable on our GE8's.

 

That'd be awesome if you could!

 

i'd need the whole circuit, you only have the one around the gages,
That said, I believe you have lost the ground connection for the gages. Thats the little erath symbol with the wire connected to the right of the fuel meter.
Try getting to the gages ground wire and temporarily clipping a connector wire from the gage ground wire to the chassis and see if they function. If they do you'll have to trace the ground wire. Be aware that the disconnect can be at the gages - and others - not just the ground cable. Worse, if the grounds in your replacement gages are in series, meaning one after another then a bad connection in a gage could be the culprit. and for that you need a volt-ohm-meter.

 

Well, given that two different people report that the jdm cluster drops the illumination, I'd guess that its not a bad ground but that the jdm cluster just works differently. Unless jnesselroad got his from jamy, in which case ignore.

 

Yeah he bought it from me after mine got totaled. Was a real pain in the ass sneaking that part out of the junk yard..

 

Why do you assume that because the jdm drops illumination, its not a bad ground?
