DIY - E36 window switch retrofit

[CarsSuck]

Done - light comes on - all buttons work. I used stock e30 wires to e36 blue base pins. (switch without the e36 harness part)

So there is no need to splice wires? Just plug and play?

[BDSax]

i doubt it, they probably sell the connector but not the wires.

Anybody know exactly what colors need to be matched up with what? I'm using the blue base.

[BDSax]

oh my god.......... look back a couple pages, i listed every one!

[franco90]

so do I wire them with no wires

[EMPWRD]

:ohsnap:

[franco90]

yet i call BMA and they said harness are goingto be $$$$$$$$$$$$$$$$$$$
so does any one have extra harness they want to sell

[franco90]

i went through the shit load of e36 switch i have gotten and figured out what did what.

E30 Switch:

Window Up 1 - Black or (Black/Grey)
Positive (+) 3 - Green/Grey
Negitive (-) 4 - Brown
Negitive (-) 5 - Brown
7 - Black Yellow (i had this, it did nothing)
Window Down 8 - Purple

The e30 switch is very confusing...... there are tabs that come from the up and down leads and its always touching, im guessing it has more resistence the more it is pushed down.
I tried to go from Power (Green/Grey) to the down lead (Purple) and it blew the curcuit. so im guessing it controlls the amount of voltage? thats what im confused about.

E36 Blue Base:

Negitive (-) 1 - Black/Yellow
Window Down 3 - Blue
Window Up 4 - Black
Positive (+) 5 - Green/Grey
Negitive (-) 6 - Blue/Green

I think that the blue/green ground is the stupidest thing i have ever seen


There are 3 different White Basee switches that i had, please check your colors. the Numbers on the switches still all lined up.

E36 White Base #1:

Negitive (-) 1 - Brown
Window Down 3 - Black/Yellow
Window Up 4 - Blue/Green
Positive (+) 5 - Red/Brown


E36 White Base #2:

Negitive (-) 1 - Brown
Window Down 3 - Purple/Grey
Window Up 4 - Black/Grey
Positive (+) 5 - Red/Brown


E36 White Base #3:

Negitive (-) 1 - Brown
Window Down 3 - Black
Window Up 4 - Green
Positive (+) 5 - Red


I havent tried hooking up any switches yet, but i tried the Green base switch. it didnt work except the bulb lit up.
Every switch i went through had a blown bulb. so if your bulb isnt working its because its blown. im going to change mine to LEDs, i think these little POS bulbs suck. i will be installing mine soon. i hope this helps some people
