Exclamation Electrically F*cked

I need some MAJOR help

i'm just going to get right into it

earlier today i hardwired a valentine one into my buddie's e46, used a brown ground wire and green and blue power wire from the universal transmitter pre-wire, to attach the v1, worked perfectly

i had already planned to wrap my selector rod with solder for a cheap weighted selector rod as detailed on understeer.com

here:

http://www.understeer.com/cheapwsr.shtml

so i figure what the heck might as well do my valentine one as well, since i already had a project planned

get home

first thing i do is try connecting the v1 to the sunroof switch via black/yellow wire which i believe to be power, and brown ground wire

when i turned on the valetine, the sunroof opened

i'm thinking in my haste i tapped the wires after the switch not before

basically then the sunroof wouldn't close or do anything, it seemed like it was dead, so i get my allen wrench out and close the sunroof manually

then i think oh well i'll take that into work(bmw dealership) tommorow and figure it out probably not a big deal

so then i searched google got a thread from bimmerforums that said use the purple and white hote wire from map/dome light assembly and brown ground wire

so i try that with the wire tap crimp connections

still nothing

after i tried that the map/dome lights don't work

i figure ok done with that do the selector rod

so i do the selector rod

put the car back down

i go to start the car, car starts and immediately dies, basically my life is over is what i'm thinking lol, icv stuck closed? who knows, maybe it's not getting power because of all the electrical problems,

the engine will stay on if i keep the gas pressed in

but as soon as i take my foot of the gas it dies

also during this whole dieing situation, obc read tailight failure, and the driver's side taillight and parking light weren't working, but the turn signal was

then i checked windows they don't work either, and niether do the vanity lights? above the sun visors

so here's where i'm at now:

1)engine turns on, dies immediately, will stay on however if i stay on the gas
(i'm assuming icv isn't getting power with the elctrical mishaps, just assuming)
2)sunroof doesn't move at all
3)windows don't move
4)driver side tail light out
5)driver side parking light won't come on
6)vanity lights out
7)map/dome light out

basically if all else fails i'll have to tow it to my work and hope my boss can hook me up, doubt it though, but i'm definitely going to talk to someone at work tommorow

basically i need help, i rushed something, and continued to rush things, until i thouroughly screwed myself over, and well just looking for any help at all

thanks in advance

I would start by taking it back out and getting the car back to OE. Then recheck all the fuses, make sure to check the power distrubution box under the hood as well. Sounds to me like you have blown one of the major fuses under the hood. General rule of thumb: If you install something and something else stops working, take out what you installed and see if everything starts working again.

Good luck,
Paco

+1 to Paco's reply, i would check for blown fuses and i will also try to put things back together as they were before, that might solve ur problem.

Hope everything works out fine.

well apparently 2a.m. in a dimmly lit garage when you're exhausted and upset isn't a good time or place to check for blown fuses, because i checked the fuses last night multiple times and didn't see anything wrong, got it into the sunlight today, saw 3 clearly blown fuses, switched em out, everything works fine, just have to figure out how to CORRECTLY hardwire a v1 to an e36 now

thanks to everyone for the help

Disconnect the Battery First. That way nothing can short.

I would run a seperate power wire from a known switched power source, to a known ground. Look at the bently manual stickied here. Dont run a power wire from the vanity light. It comes on even when the car is off. You want something that comes on when the ignition turns on. The sunroof is good because you wont overload that circuit, the sun roof isnt always opening and closing, plus i think it is switched. If ALL else fails just hookup a relay to a known switched source to the main power that comes into the fuse box. It will be alot of wiring but you end up creating your own circuit, and it is hard to crew anything up that way, however it is a bit unnecessary.

Ill try and find a DIY for you, hope it goes well. O and remember to fuse your new circuit so u dont catch your car on fire. That would be bad.

Use the sunroof feed....

Yeah when I wired my V1 I used that black hardwire plugin thing that comes with the V1 kit and wired that to the sunroof power feed (it is definitely switched power....) and drilled a pass-thru hole in a non-visible spot in the headliner to pass the power cable through. I just stuffed all the excess wiring inside the sunroof headliner area, fits in there Ok. Then clipped the V1 to the passenger side visor to keep it kind of hidden and out of the direct sunlight. Works like a charm and never had a problem with any of it.
