Here is a picture of the engine compartment Relay Board of my '73. Will someone post a picture of what this should look like?
I've had the car for a short time and am learning about all the wiring work arounds. Note the car is running carbs. Three things I'll point out in this picture are: 1. The ignition harness coming off the board has a red crimped connector in it. Might need one of Jeff's new harnesses (?). 2. The brown (ground) wire on the left bottom is unconnected. Where should it run to? 3. Bottom right of photo is a blue wire coming from under the dash - will deal with in a later posting. Not in the photo, the ignition key has been bypassed with a push button installed on the dash. Still needs key in and on to start.  |

Looks like someone was trying to do the correct thing and use the stock fuel pump location and wiring for the new low pressure carb fuel pump. In which case that brown wire should be connected to ground. http://www.914world.com/specs/SirAndyCarbFuelPumpRelay.php Not sure which terminal that goes to on yours, kinda hard to see and i'm not sure if all of those 4 terminals work the same way, but if you follow the link above it shows what i did on my carbed 2056 to retain the stock fuel pump wiring when converting to carbs.

Jeff, I'm doing carb conversion on my 73'. Does the ignition harness need to be modified? or some pins not used? |
