It has been three years since the car drove but i have finally rebuilt the engine and reinstalled it. Now i'm trying to wire it all up. Too bad i didn't keep a record of where everything went.
I'm looking at the relay board diagram and most of the wires are accounted for except a few oddballs don't seem to match. The car is a '74 with a 1.8 on Webbers Wires in italics are not accounted for I think these wires go to the area outlined in red on the Relay Board Diagram (to be posted) Here we have the following wires: Green w/ Red Stripe Green w/ Black stripe Green (2) Grey w/ Brown Stripe Black w/ Red Stripe Black w/ Purple Stripe White Thick Yellow which turns into Red |

You are correct that the wires from Post 1 go to the red connector and those from Post 2 go to the green connector. As mentioned, you should really try to procure the plastic connectors that these wires go to. Put a WTB: ad in the classifieds for the 2 connectors.
Use your voltmeter to check all wires to make sure you get the right ones. Don't go by what I tell you. Check these wires yourself to be sure. Show some pics where the other ends of the wires in question go and we should be able to help figure this out. From Post 1: Thick yellow which turns to red: I don't know what this means that yellow turns to red, but the thick yellow wire from this connector could be to pin 6 which goes to the starter. Here are the wire colors and connections from my 74 schematic from my Haynes manual: Pin 1 GR/RD Oil Pressure Pin 2 GY/BR Backup Light Pin 4 GY/BR Backup Light Pin 5 BK/PU Tach Pin 6 YW Starter Pin 7 BK 12V to Coil Pin 10 GREEN Heater Blower Pin 11 GREEN Heater Blower Pin 12 BK/RD Supplementary Air Valve From Post 2: Here's what my schematic says: Pin 1 YW Starter Pin 2 BL Alternator Light Pin 3 GY/BR Backup Light Pin 4 GY/BR Backup Light Pin 5 GR/RD Oil Pressure Pin 7 BK/PU Tach Pin 8 BK 12V to Coil Pin 9 GR/WH Heater Blower Switch Pin 10 BR Ground Pin 11 GR Heater Blower Pin 12 RD Battery Pin 13 BK/RD Fuel Pump Pin 14 RD Battery |
