SO here is my situation rn. NO running lights, dash light. I do have brake lights, headlight, front, rear, and side indicator lights.
First, I went and checked the fuses located at the driver's kick panel. Check the tail, stop, and hazard fuses using a power probe and found 12V at each contact point of the fuse. Does this mean that this junction box is receiving 12v from the fuse box located in the engine bay?
Second, I went to the 60-amp BTN fuse, located at the engine bay fuse box. found 0.4 ohms. Did a voltage drop at the contact point of the fuse, and found source voltage. Next, I went to the 120-amp fuse. found 0 ohms
At this point, I was thinking maybe the headlight switch? So I pulled the TNS relay to see if I would find ground at the bottom right contact of the relay. Found ground. Next, I wanted to see if I would find 12V at the bottom left of the relay, and found no voltage.
After finding no 12v at the relay, I did some physical damage checks on the wiring loom located at the fender liner and fusebox, and found no signs of damage. WHAT DO I CHECK NEXT!? I'm CLUELESS

 

Page Z-58 in the wiring diagram shows the circuit. I'm not sure about your top/right or bottom/right contact labeling, but with the relay removed it looks like two of the sockets on the relay connector should have 12V power. That power comes from the White/Green wire, which connects via connector X-08 and gets power from the 15A TAIL fuse in the kick panel. If all your fuses look good, I would find the X-08 connector and make sure it's connected. The drawing isn't as clear as I'd like, but the location looks like it's near the dash and driver side footwell.

 

Would the wiring harness for an LHD FD same as that for an RHD FD?

 

Pull the TNS relay, put a jumper between the two terminals that have the thicker gauge wire (WhiteGreen & RedBlack). Do the marker lights work?
If "BTN" and "tail" fuses are both good you should have 12V on the White-Green wire at the TNS relay.

From the LHD '94 wiring diagram, I don't know if RHD is the same.

 

All the marker lights work. I think it's kinda pointless to jump the 12v circuit from the relay, no? The problem is that I am not receiving any 12V to the relay. So even tho I have switch to ground, there is no 12v passing through the 12v circuit, that's why I am not hearing any relay clicking??? Correct me, please. My problem now is that I don't have a service manual for a JDM FD, so I have no clue where everything is...

 

If ANY of the side marker lights work, the TNS relay is clearly not your problem. Note that all the lights in that schematic are on a parallel circuit, and power to all passes thru the TNS relay, so if ANY of these lights work, the TNS relay is good. BUT groups of these lights ground to different ground points as shown on the diagram, and on the hot (+) side of the circuit, power to some of the groups of lights needs to pass thru JB04, and JB03 or JB02. Specifically, which lights don't work? Focus on tracing ground & power to those bad lights per the schematic - the ones that don't work will either have a broken path to ground OR a broken path to the + side (via the associated JB connectors) as applicable .

WRT electrical schematics, the LHD & RHD should be the same functionally, but there may be some differences WRT the physical locations of components and perhaps wire colors - not enough to stop you from troubleshooting with the schematic you have.

 

As Pete mentioned, you haven't presented your actual issue clearly. Initially you said no running lights or dash lights, and then stated you have side markers....which are running lights.

If by no running lights you mean interior illumination and the cluster lighting, make sure that that the instrument harness that runs along the dash bar is plugged into the joint box at connection JB-02. If that connection is solid your dimmer switch may have failed, pull it out, unplug it, switch the lights on, and run a ground jumper between the RedGreen wire and the chassis, the interior dash and cluster lights should illuminate at 100%. If the dimmer has failed, none of the dash/cluster lighting will operate.

Side note, a poor connection at ground point #6 will prevent the dash/cluster lighting from illuminating as well. If the dash has never been removed and the instrument harness has not been touched, the issue is probably the dimmer switch.

....Make sure the dimmer is not rolled all the way down to zero as well.

 

I think I confused the side marker as the indicator lights on the fender? sorry about that😅

 

The TNS circuit is your problem then. The turn signals are not on that circuit.

 

Been trying to find X-08 connector for the tns circuit but found out that it's for the fuel pump circuit 💀. here is the jdm version. So here is what I found at the X-11 connector W/G wire. any idea what could cause the wire to melt? I don't have anything tap into the circuit that could cause this..
