      After an engine failure this thing has been cornered for way too long... Techtonics helped me out with an engine build and now she is close to being back in business. Went ahead and rewired the tattered harness while the motor was out. Ordered a new carpet kit. It's coming along.

      Got the car started but the center gauges weren't working correctly. So one thing led to another and the dash came out. Dirkwright's disease set in and I went ahead and replaced the evaporator and heater core. Blower motor was tired so I found an NOS one and put that in. The stereo wire was a mess so I pulled it all out, removed door cards, and yanked all of that. Then proceeded to build new speaker supports, R and R the power windows and service, clean and grease power side mirrors and switch, and now I'm waiting on some butyl tape to build vapor barriers.

      Cleaned up tons of hacked wiring and I ahve it all figured out but one wire that seems really important but I'm not sure where it should land. It's a black wire that was hanging out by the radio. It runs back cluster on the black connector. A2resource says it's "Start/Run Power". Anyone have an idea what this wire is for?

      Also, the cluster has this flappy piece on the circuit board. Is that normal?

      Nice looking Scirocco. I guess you must not have the Bentley manual.

      T7c/7 goes to the ignition switch terminal 15.

      Haha Cut me some slack. I at least did the A2 resource effort and didn’t walk in with both hands out. 😃

      I do have a Bentley but I’m really struggling to interpret the wiring diagram. It’s killing me. I’m going to grab my Bentley and try to understand how you got the answer. May even see if I can pester you with a couple of other Bentley interpretations if you’ll oblige. Thanks for your help

      It's simple. The VW "Current Flow Diagrams" are the easiest wiring diagrams I have ever used. By far.

      The directions are in the first few pages of the electrical section but I will give you a quick down and dirty. The area at the bottom is called a "current track" the numbers are like map coordinates. They mean nothing in the real world much like there are no markings on the earth that correspond to coordinates on a map.

      Ground goes to the bottom to the current track in most cases. If they don't go to the bottom, they terminate in a circle with a number. You can look up where those grounds are in the index also.

      In most cases grounds the go to the bottom are identified by a circle with a number also. In cases where there is a thin line the ends at the current track, those grounds just go directly to the closest ground (like the engine block for a temp sensor).

      Power comes from the top except for the battery and alternator sources.

      The top grey rectangular area represents the Relay Plate (fuse box) and you will find most but not all fuses and relays there. You will also find power running through there.

      On the first page of each car's electrical diagrams is the index where you can look up various components. It also tells approximately where to find connectors in the actual car (but not in the current flow diagrams for some reason).

      I didn't use the index. I scanned the wiring diagrams until I located T7c/7.

      The Scirocco 16V has its own section for the Electronic Engine Controls. Do not use that section of the main current diagram. The ignition switch is common to both 8V and 16V and is in the main section.


      About A2 Resource, I hope you looked at a VW A1 wiring diagram instead of an A2 wiring diagram.

      You look up components in the index and that tells you what current track (or map coordinate) it's closest to. Most often you find the current track then go up from there towards the Relay Plate and find the component some place in between. If it's a relay, it's usually up in the relay plate area.

      There are also separate current diagrams for A/C, power windows, the stereo and possibly other options. That applies to all cars covered in the manual.

      So it's alive but the oil light is blinking. I narrowed it down to the one wire I couldn't find a landing point for. Mechanical gauge says I have oil pressure so I'm not scared but I can't stand the light blinking.
      Its this green/black wire

      Smashing baby, yeah!

      You have an absolutely gorgeous Scirocco. Well done. I like the eyebrow spoiler (if that's what they're called?), the leather seats, the bumpers, the headlights, wheels.. Mine is red and yet if you parked them side by side there's enough differences between the two. Yours is much more individualized of course, and I'm no purist. Big fan of what you've done with it.
      They say people don't believe in heroes anymore. Well damn them! We're gonna give 'em back their heroes. One Scirocco at a time.

      Thanks for the props man. Been a lot of work.
      I can’t take credit for the mods. I bought the car already setup around 7 years ago. Since then I’ve gutted the bay and rebuilt everything (engine, trans, wiring harness, fuel dizzy, etc). The car has fought me for a long time. It’s finally there though. Still needs an alignment and something on the ac blower is acting up. Future plans are old school, period, custom wheels, redo the seats, exhaust (since it’s sort of pieced together), and some coil overs to dial in the ride height. After that she will be perfection.

      It's supposed to go next to the fuse panel. The wire that plugs into it should be G/BK and 0.5 mm (the same color and size). One side goes to the Oil Temperature gauge in the console and one side to the sender.

      Oh, 126 just refers to the location on the drawing. It's like a map coordinate. It has nothing to do with reality. It's a way to locate things on the drawing. Read the "how to read Current Flow Diagrams" section. Easy as pie and by far the easiest wiring diagrams I have ever read.

      Ground is on the bottom of the page which is where 126 is located. The sender is grounded through the engine block. The numbers in circles are ground points. You can find their locations by looking them up.

      If you don't have the oil temperature gauge in the console next to the ashtray, then that is why that connector with the G/BK wire is not connected.

      I noticed you mentioned a mechanical oil gauge.

      None of my Sciroccos had a oil pressure gauge, just the oil temperature gauge. My '78, my '82 and my '88 all had an oil temperature gauge. No oil pressure gauge. Flashing low oil pressure idiot light only. The light comes on as you are starting the car just to show you the light works but it goes out after it starts.

      My 16V is a 1988 but I think other years were the same.

      EDIT: I see in your interior picture that you have a 3 gauge panel. If one of those is the stock Oil Temperature Gauge then that's where that wire is supposed to end up. The other side goes to the sender.
