93 Rx7 Dash,sidemarkers,blinkers wont light up
 

Hello hope you all are well, I'm new to the Rx7 world. I have a 1993 rx7 and I'm having issues getting the dash and exterior lights to work (headlights/motors work perfect). I read that it might be the TNS relay, so I check the relay box by the hood latch and come across this.

These 2 sections circled in WHITE arent connected to anything.(this is the Front Harness that is currently on the car)

I also have this spare front harness but this one only has 1 section (circled in white) that isnt being used.

Could this be the problem that might be causing my lights to not work? Thanks!!

Any input?

Cool brother thanks I'll post on there!

There's a 15A fuse that is on the circuit with the parking lights and dash. It is located in the fuse box in the driver's side footwell area. I believe the fuse location it labeled "TAIL".

I replaced that TAIL fuse and still nothing :/

These are the only light that light up on the dash and the blue high beam light on the dash also lights up when i pull on the light switch

Have you used the trouble shooting procedures in the shop manuals?

I have read about the dimmer switch causing similar issues.

However, I would just use the shop manual to isolate.

Check CPU #2, under the steering column. Might need replacement. Noticed mine was bad when my indicators suddenly decided they wanted to stop working. It was during the day, so, I'm not 100% if it had to do with the cluster lights.
