Hey Eddie, I made a list and it is on my CD inside the Wiring Folder. Here it is.

Relays=>
---------------------------
Center Console -
Marker lights
Headlights
Roadster Round Fog
Roadster Rectangle Fog
Hazard - powers flasher supply>4 diodes to each light.
Door Lock
Door Unlock
Interior Light
Gas Door Solenoid (did not use on the Roadster)

Power Windows 4 relays > left up, left down, right up, right down. I used relays so that pulse could be sent to the window relays without going to ground if I were to use only the window switches. (Both up and down on the window switch remain NC to ground)

Heater Controller - I used 11 relays to protect the switches only.

Dash Area-
Starter (to protect micro switch on clutch pedal)
Brake lights
Headlight dimmer> (30 from headlight relay#87 > Dimmer Relay 87A Low Beams > 87 High Beam)
Horn

Rear Above Gas Tank-
Fuel Pump

Left Rear Above Battery-
AC Condensor Fan
Left Fan
Right Fan

That Totals 32 Relays.
I added an alarm system and had to convert positive to negative 2 more relays needed. Total 34 relays.

I did not use a relay on the reverse lights or wiper system.

----------------------------------

I used 10 gauge wire for battery supply to ignition switch, all rad fan wiring, frame grounds.

14 gauge wire for all electrical devices that used a relay.

16 gauge wire for all the gauges and idiot lights.

I have discovered that BMW has a relay module hidden under the left rear seat. I have access to two of them with the wire harnesses. I sorted the wires out and I plan on using them. It allows me 24 usable relays, the cool thing is the load wires (87) are grounded when not in use. This means I can run power door locks and windows without any problems.
They also take up alot less room.

Jim

Starting bid is $15.00 (equals 12 relays) not a bad deal if it fails in the future.

On the alternator there is an 'L' molded into the plastic wire connector. I believe it is even on that connector.
I am color blind so I never used color to identify the wire during the whole project.

We looked closely and there are no markings on the connector. Greg, take a look at the connection point on the alternator. I don't think I looked at it.

From what I gather without seeing the alternator again it is the GREY wire in the above picture.
Do not connect it too the computer wire harness lead. Just tape up that wire from the computer.
I have a picture on my CD in the 'Wiring and Drawings' folder called 'Alternator Wires'.
This shows how to connect it to the dash light and that is all you need.

I was a little scared when I pulled this harness out of the box, but after I layed it all out it wasn't that bad. Of course it has nice labels the say "Light group"

I only see two wires to each door. You will need to add a few more.
I have this list on my website that may help you. This list shows 13 wires to each door (1 spare) with their minimum gauge size.

It looks very nice but you need to think of where the wiper motor is going to fit.
The real deal has a velcro carpet panel is the passenger foot box. They are mounted on the upright wall at the passengers feet.
