Default Parking lights cluster lights and tail lights stuck on

All of my lights are stuck on and will not turn off, disconnecting the battery is getting old and annoying! The clock is dim usually until the parking lights turn off at random when I reconnect the battery to go home from work

Start by unplugging the Combination Light Switch, if the lights go out, replace the switch, if not you have a short, [cross] between your park/dash lights wiring, [red/black] and a constant power lead, [there are a number of constant power leads].

Is that your car in the pix Hondadaturbo posted?
If so, check out your local bone yards, [PicknPull] to see if you can find an undamaged dash harness. 94

Yes I had to make a new profile ...but I did some poking around ...I ended up pulling that ecu fuse under the hood and all of those lights turned off ...so my next question is ..is that wire to the Ecu 12v constant ...and does that wire run under the dash to the fuse box because now I know there the parking lights are shorted to...and I'm assuming the previous owner wired it to something behind the fuse box

Yes the ECU/ECM power lead must run into/under the dash as that is where the ECU/ECM is.

However, the "short" can still be in the engine bay as both that power lead and the park light circuit leads are also in the engine bay, [enter/exit the pass. compartment at the same point].

Also, on most Honda/Acura, the ECU/ECM memory fuse, [constant power fuse] is also memory for the stock radio.

If you have an aftermarket stereo, pull it and check the red/black lead, [illumination, and not used for most aftermarket HUs] and the white/blue, [or white yellow] lead [memory and will/should be connected to the aftermarket HUs yellow constant power lead]. 94

Yes the yellow constant power lead is connected to the radio the red/black lead has 12v constant power and white/blue is constant as we'll even when the car is off

Is the red/black lead, [at OEM radio harness] connected to anything?

What is the white/blue OEM lead connected to?

What is the stereos yellow lead connected to?

The red/black is an illumination lead and should not have power on it, yours does because the park/dash lights are staying on. 94

It's running through the radio harness ...white/blue is going to 12v constant on the radio (yellow) red/black goes to orange white on the radio harness ...not oem radio

Try disconnectint the red/black and orange white, or to test just unplug the stereo. 94

Then you will have to find where in the wiring harness the red/black and white/blue are making contact with each other.

Start where the white/blue runs from the under hood use box into the car.

What is the MM&Y, [and trim level] of the car? 94

Hey, mine is also a 94RS.

I will look up the wiring on Mitchel after lunch, maybe I can see a possible spot for the "short". 94

Okay sounds good! I just have to find that kill switch I think that's what's messing up everything

"Kill switch"?

That 7.5A powers the ECM, TCM, radio, clock and maintenance reminder unit.
The clock will also have a red/black illumination lead, try unplugging the clock. 94

Yes kill switch the car has one to where the car won't start unless the parking lights are turned on I can't seem to find it because I know that's where the short is ...I pulled the ecu fuse the 15a under hood fuse and all of the lights turned off but triggered a solid CEL

It seems as though the previous owner grounded out the ecu circuit to that parking light switch...but I doesn't work anymore

The park light circuit is not connected to the ECU/ECM in any way, unless the PO did so.

You said, "...I pulled the ecu fuse the 15a under hood fuse", exactly what fuse is that, there are no 15A fuses for the ECU/ECM.

Fuses for ECU/ECM are...

Fuse 18 - 7.5A, [hot when cranking to start only] under dash fuse box, [blue/white]
Fuse 32 - 7.5A, [hot at all times] engine bay fuse box, [white/blue].

Also, looking at the pic you posted of your fuse box, the fuses used and locations are not what Mitchell indicates, wrong size fuses in some spots and fuses in spots there should be no fuse.

Also, what is the white lead "plugged" into what looks like fuse 11, [not used in an RS] or it may be fuse 23 - 30A, [should be a 15A] for stereo/cig. lighter???

Having higher amp. fuse in locations meant for lower amp ones can result in damage to wiring, and is a fire hazard. 94

Under hood fuse says 15a FI E/M then 7.5A back up (radio) that's from left to right

I pulled the fi e/m fuse and all the lights turned off I haven't touched anything on the fuse box since I got the car since i don't have an accurate enough fuse box diagram
That white lead was a temporary use for a wide band on the dyno

The 7.5A, radio back-up, [memory] is also ECU/ECM memory for the ECU/ECM and the clock.

The 15A fuse, [fi e/m] is the main power input to the PGM-FI Main Relay, [fuel injector relay] pulling it will get you a CEL even though it does not directly power the ECU/ECM.

The output of the fuel injector relay not only powers the fuel injectors and some engine solenoid/valves/sensors, it also is IGP1 and IGP2 inputs to the ECU/ECM.

Drop the PGM-FI Main Relay, [just above hood release] and see if any wiring is connected to the harness, the 15A is on the yellow/white lead.

There is no illumination wiring, [red/black] going to the PGM-FI Main Relay.

How about that white lead running to the under dash fuse box, what is it for? 94

That white lead was for a wide band sensor at the dyno temporary power.

I'm not saying that there's a wire that feeds to it ...I'm saying that the previous owner wired it up like that

When the killswitch worked you would turn the key to on ...
The fuel pump does not prime ..it's just a solid check engine light

Until you turn the parking lights on then the check engine light turns off and the fuel pump turns on then you can start it...

If the car is running and u turn the parking lights off the car dies

But it doesn't work anymore

For temp. or extra powers you can use the free pins, marked red/white and orange on the first pix I posted.

So what it sound like is happening is the "cut" was installed on the 12V constant for the
PG-FI Main Relay, you need to drop the PGM-FI Main Relay. 94
