I was fixing my alarm hood pin switch and interior piezo siren today. After doing that, I reconnected my battery and bam I discovered that there's a million things not working.

The dome light does light up anymore when the doors open. I even manually pressed in and out the factory door pins. If I switch the dome light switch to the ON position, it would light up, but when switched to the DOOR position, it's completely dead.

Now when I arm my car, it doesn't lock and unlock the doors anymore.

The remote trunk pop stopped working.

The secondary alarm sirens stopped sounding.

Usually whenever my alarm fails me, I can use the OEM Honda remote transmitter to lock and unlock the door. I just tried it, and it does not work anymore.

I think there might be a blown fuse somewhere, because a whole bunch of stuff stopped working at once. Is there a Honda factory fuse that controls the dome light door open indicator?

Any guess as to what may be wrong?

 

wire the car up like it was when it was working and then diagnose your problem
reverse engineer ...kinda

 

put it back to how it was before..
just hooking up a hood pin switch and a siren shouldnt do anything. but im guessing you wired it incorrectly someplace...

 

the stock keyless entry and the dome light are controled off of the radio what year and what kind of car is it

 

1993 EX coupe

I didn't do anything to the wiring at all. All I did was remove the electrical tape wrapped around all the wires. When it was on, I would move the wires with my hand and get a signal for the electrical sometimes.

Now that the covering is off, nothing. No electrical to the fuel pump relay, no radio, no CEL, no nothing.

I'm about to just buy a multimeter and start checking continuity.
