The ignition harness from my '73 is fried but I found a harness in my spare parts that needs a few minor repairs, but cleaned up pretty nice.
This may have come out of my old '74 VW bus but is identical to the fried harness with the exception of the size of the yellow wire running to the starter. The wire on the good harness is smaller (probably 2.0/14 gauge) compared with the original harness. I can't find wire sizes on the '73 wiring diagrams, but the '74 diagrams indicate a 4.0 mm^2 wire which would be about 11 gauge. Would you replace that wire? Seems like this one might be size critical. I'm thinking of replacing with 12 gauge. I think 10 gauge might cause fitment problems at the 12-pin terminal. Or is it fine like it is. What do you think?

Thanks again Jeff! I guess a PO had replaced this harness in one of those other 914s with a '72. That doesn't surprise me. But I now see this harness fits the '72 schematic. I didn't mention that the largest casing near the connector is bunged up and will be replaced. So replacing the yellow wire shouldn't be difficult "while I'm in there". And I'm glad my first instinct to remove the brown and green wires wasn't wrong after all. Another difference is that this harness was missing the jumper between pins 10 and 11 to send power to the heater fan relay. I transferred that jumper over since it was the only wire not scorched by a shorted tach wire. This will be a proper '73 harness before I'm done. (IMG:style_emoticons/default/beer.gif)
