I have a 1971 super beetle vin 1112500000 and it has a wiring spider web under the hood. I have look at the samba page on this and have some of the wiring figured out. But, the wiring loom doesnt match the color codes?

The pass through wiring is a question as all I can find is higher vin numbers which dont wash... Also the past owner took out the t blocks for some reason so all I have is wires... Trying to get it back to stock wiring and it a spider web.

Any idea's anyone?

Pics of your trunk area behind the dash might be a starting place. Focus on the wire colors coming from the different harnesses of wires and the trunk side of the fuse box. There are basically the following collection of wire in sleeves:

Main harness running between the dash area to the left rear seat and the engine.
Lighting harness running along with the main that contains the rear lighting wires.
Left front lighting.
Left front brake switches and horn.
Right front lighting.

Identify these different groups of wires and the wire colors in the sleeves.

Post pics of how the wires are junctioned if the T-connectors have been removed? Are they just taped together?

Which wires are specifically not the same color as the stock wiring diagram? Post pics of these wires with comments of what the wires are connected to.

I grouped the wire colors you posted into logical groups of wires that typically collect inside sleeve(s) to become a harness of wires. All wire colors align with the wiring diagram above. If your wires have been replaced they may not match and you will need to transpose the wire colors.

Right front lights
Gray wire - Parking/marker light (from fuse #1 OUTPUT)
Black/green - Right turn signal from T2 4-way junction (four black/green wires)
Yellow/black - Right low beam (from fuse #3 OUTPUT)
White/black - Right high beam (from fuse #5 OUTPUT)
Brown - Ground wire for headlight and parking/turn signal assembly. Grounds just after the wire enters the trunk.

Left front lights
Gray wire - Parking/marker light (from fuse #1 OUTPUT)
Black/white - Left turn signal from T2 4-way junction (four black/white wires)
Yellow - Left low beam (from fuse #4 OUTPUT)
White - Left high beam (from fuse #5 OUTPUT)
Brown - Ground wire for headlight and parking/turn signal assembly. Grounds just after the wire enters the trunk.

Left front brakes & horn
Black - Brake & Horn power (from fuse #10 OUTPUT) to T3 where it splits into Black wire to MC switches; Black/yellow to horn (+)
Black/red - OUTPUT from MC brake switches to rear brake lights via T3. A single wire runs to the rear where it splits into a left and a right.
Red - OUTPUT from MC brake switches to Brake Warning lamp
Brown - Horn (-) wire to turn signal switch assembly via T3. When this wire is grounded the horn sounds.

Ignition switch (D) - In the wiring diagram the entire steering column appears as a single device, but it is made up of the ignition/starter switch (D), the turn signal & headlight dimmer switch (E2) and the horn button (H). That is actually 5 switches inside three assemblies (ignition switch electrical, turn signal switch assembly, horn button).
Red - #30 constant battery 12v+ INPUT (from fuse #8 INPUT)
Black - #15 ignition switched OUTPT (to fuse #11 INPUT)
Red/black - #50 OUTPUT to starter solenoid via T5 where it turns into a solid red wire
Black/yellow - #X OUTOUT to headlight switch X terminal. This powers the headlights.
Grey - #SU OUTPUT ground to door buzzer via door switch while key is inserted

Turn signal switch assembly (E2 and H)
Black/green/white - INPUT to turn signal switch from flasher relay #49a
Black/green - OUTPUT from turn signal switch (RIGHT) to T2 4-way junction (four black/green wires)
Black/white - OUTPUT from turn signal switch (LEFT) to T2 4-way junction (four black/white wires)
Brown - GROUND wire for dimmer switch
Brown/white - dimmer switch OUTPUT to headlight dimmer relay S terminal
Brown (or sometimes Brown/blue) - Horn contact on face of switch. Connects to the horn (-) wire coming from the horn and the horn contact ring on the underside of the steering wheel.

Main Harness
Red - #30 constant battery 12v+ from VR B+ to fuse box (to fuse #9 INPUT). This single wire powers pretty much everything.
Red/black (or solid red) - Starter solenoid #50 from ignition switch to starter solenoid.
Blue - #61 terminal on VR from GEN lamp. The VR grounds this wire to turn the GEN lamp ON.

Engine / Rear lights - These are in the main harness but once the main harness reaches the left rear seat these continue on into the engine compartment
Black - #15 ignition coil power to ignition coil #15 (+) (from fuse #12 INPUT)
Blue/green - OIL lamp, switched ground from OIL lamp to oil pressure switch below distributor
Gray/black - Left rear parking light from fuse #2 OUTPUT
Gray/red - Right rear parking & License plate lights from fuse #1 OUTPUT
Black/green - Right turn signals. From black/green T2 4-way to rear
Black/white - Left turn signals. From black/white T2 4-way to rear
Black/red - Switched single brake light wire from MC switches to rear brake lights. Wire runs to left rear T4 before splitting and running to right brake light.

VR-to-Generator - Wires between VR under rear seat and generator
Red - heavy gauge D+ wire
Green - DF "field" wire
Brown - (D-) Ground wire between frame of VR and body of generator

Reverse lights
This circuit starts from the ignition coil #15 (+) with a black wire. It runs to an inline 8A fuse before wrapping around the right side of the fan shroud and passing thru the firewall tin to reach the reverse switch at the front of the transmission. The return wire (still black) comes back into the engine compartment before splitting into a right/left side. These black wires run to the rear light T3/T4 junctions where they connect to the solid blue wire in the taillight assemblies to power the reverse lamps.

In general, most of your wire colors appear to match the wiring diagram. There were only three (3) wires I wasn't sure of:

Green wire (Back harness #5) - You did not note the presence of a blue/green wire in the main harness running from the OIL lamp in the speedometer to the oil pressure switch below the distributor. So I'm thinking your green wire could be for the OIL lamp?? The only other common solid green wire is the short wire running between the points/condenser on the distributor and the ignition coil #1 (-) terminal.

White wire (Ignition switch #7) - The white wire you describe from the ignition switch sounds like the grey SU wire from the ignition switch to the door switch and then the door buzzer. When the key is in and the door opened the buzzer relay is grounded. The only other solid white wires are:
Power wire between E-Flasher switch (+) to the flasher relay (+). This powers the flasher relay.
Left front high beam wire
Short white wire running from the headlight dimmer relay F to the fuse #6 INPUT

Blue/white wire - This color is common for the High Beam indicator lamp in the speedometer. It is powered from fuse #6 when the high beams are ON. Also, the license plate light wire running from the right parking light wire (grey/red) is sometimes blue/white between the right rear junction and the license plate lamp.

There are lots of other wires not covered above but these are not in a harness. They are loose and run between different devices. Use the wiring diagram to identify and wire these.
You will also note in the wiring diagram many short wires that end in an orange circle with a number of symbol. These are the diagnostic plug wires. All run back to the diagnostic plug in the engine compartment and terminate with the indicated number/symbol.

Ashman,

thank you for sorting this, i just needed someone's help to sort this as its a bundle of fun. My Super Beetle is very early in the serious and don't want any fires from miss wiring It is not rocket science but can get confusing when diagrams don't match and didn't have the pass through straight wiring. Thanks again for the help. HayBob VW71

If you plan to work on the Beetle electrical system you really need to get comfortable with the wiring diagram.
