help!, major elctrical issues

[amnash]

i have a ton of electrical issues that i need to get fixed before i try start the engine.

i accidentally put the battery leads on in the wrong order and there was a pretty big spark. when i went inside the car i smelled a slight burning rubber smell.
after waiting a bit i turn the key to see if everything was ok but nothing was..

3 out of 5 of my auto meter gauges didnt have the back-light working. the mechanical ones seem to work fine

i had a look behind the cd player/gauges and above the pedals for any damage but couldnt see anything obvious

so heres the list of problems
-electrical gauges dont work - fixed
-gauges make sounds now..didnt before - fixed
-the greddy boost controller doesn't turn on now - fixed
-turbo timer just flickers when i push power
-none of the warning lights in cluster work(should all come on for a sec every time i turn ignition)
-electric windows/mirrors dont work
-non of the exterior blinkers work(headlights work but there aftermarket hid's) - fixed


also, i dont think these are extremely important but can anybody tell me what this ground is for? and these two plugs behind the head light theres a set behind each light(the lights are all hooked up)

i hope i havnt just fried like 1500 in electronics

so im looking for guidance in what to check cuz i know no clue about electronics.
theyre must be something in the system to save everything from a surge no?

Start with fuses and hope for the best. If you're lucky all the fuses blew and none of your electronics were damaged.

If you're unlucky well....putting a battery in reverse is VERY bad.

There may also be standalone fuses on the wires themselves depending on how you're setup.

well this sucks then because there was actually no blown fuses. i was told that i could have fried my ecu and pretty much everything including the engine harness..
also was told there is a main in line fuse that could have saved me? do we have these

[DarkCaporaL]

GTRs do not have a main fuse.

GTS' should have a main 75A fuse in the engine compartment.

My gts has one but my gts4 doesn't. I would say get out the multimeter and see which ones are still getting current and which ones aren't. Also did you check on the inside for fuses or in the engine bay? Or even both I guess? Make sure all the fuses are fine and then go from there first.

[amnash]

all fuses are fine. ill have a look for that 75A fuse today.
was talking to an aircraft electritian today and he said i wont blow a fuse putting power in the wrong way only from a power spike. and my fuses are fine so that makes sence.
im going to attempt to run the ecu for codes today hoping my ecu has led lights.
even if my ecu is fried it should still be able to pull codes no?

[amnash]

also, all of my coilpacks read 0.0ohms any opinions on that?

Edit: fixed

thanks for that, i found the fuse and it was blown.

so that fuse fixed 4 out of 7 issues.

but the ones remaining are the most important..

i took a video of what going on with the cluster. im thinking the windows and the cluster have somthing in common. i meterd the cluster harnes and theres a couple pins getting 12v so it does have power. i found two grounds behind the driverside kick panel that wernt the greatest so i cleaned up with dremel then contact cleaner, no change though.

could someone tell me where in the engine bay these thing plug in(or if they do at all)
or even just have someone inside the car watching the cluster and you start unplugging stuff keeping an eye out for change, then let me know which one!!

heres a small vid, i think my timer is f@%ked

Once it stops pouring rain i'll go take a look for those plugs on my car..
