Hey guys, 

So I know the headlight issue has been beaten to death at this point on GTR's but don't think I've seen this happen and I'm at a loss at this point.

The parking lights, interior lights, and tail lights ( when not on the brake) have all gone out. However, my headlights, high beams and turn signals all work.

The park lights setting on the switch does nothing, as well as the fog light button ( its wired to act as another park light button ) 

I've checked all fuses under the driver footwell, all are intact, tested with voltmeter and good to go. Also tested the relay under the hood as well.

Being the noob I am when it comes to electrical stuff and reading so much about the faulty switch and possible burnt out wiring, I went ahead and replaced both the interior light switch and harness to rule out. No Dice Same issue. 

Ive traced out some wires off the interior harness. it appears there are 3 wires / separate circuit for park lights?

Im going to guess the Green with Red wire is battery feed? It also looks like its split into the fog light button which is making me believe is the issue.

Has anyone had this happen before?

You really need to start with some basic checks with a multimeter, that will tell you if power is getting to the switch and from the switch....there are too many places for this to fail after 30 years without knowing that

So just to clarify. 

Ive checked all fuses in the engine bay as well as under dash with multi meter. all good. tested terminals fuses are in as well to check for power. all good.

I do NOT have a fusible link as my battery has been previously relocated to my trunk and on a breaker ( currently good to go) 

I have traced the wires on the interior switch. The park circuit appears to be 3 wires / plugs on that switch, 

a red wire with grey specs, a black wire with grey specs and a Green wire with red stripe. 

I'm assuming that the green wire with the red stripe is supplying battery power as im currently getting nothing from said wire and it appears to be split/spliced into the cars fog light switch ( also acted as park lights switch ) 

 

To answer the above

Lowbeams, highbeams, dome lights and brake lights work. I have a dvd player and yes it works/ plays. 

My park lights, taillights , and dash lights do not ( triple gauges out and haltech ic7 will not flip to night mode )

9/28 update.

 

so I had a lil help and re traced and tested everything possible. 

all fuses intact, power to fuse box on all slots. 

 

Determined that the wiring in the dash for the headlight switch seems to be the culprit. 

The green wire with red appears not to be getting any voltage what so ever. 

also was able to backfeed on separate wire to test, all lights worked when doing so.

does anyone have a clear wiring diagram? my example sucks and cant seem to find any better....

need to find where this wire goes.

Being this happened about 4 years ago, i honestly forget exactly what is was, but I wound bringing to Simon at SR Werks when he was here in NY.

He was able to properly diagnose and repair. I believe it had to do with the harness behind my dash.

Yup. Mine was behind the dash. I guess after my IC7 install, the OEM cluster connectors were push into the dash, and the terminals (which are on the exterior of the connector so it contacts the traces in the cluster), contacted the chassis which caused my tail lamp fuse to blow. It also messed with my wideband. Taped them up and that fixed it.

    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
