DG,

First, THANK YOU!!

I found what looks like a broken solder joint on a pin with the solid brown wire. I checked this with a magnifying glass. It is the only pin in there that looks like it had a wire attached. If this is infact true, that brown wire leaves the box and goes to chassis ground right behind the box.

I have been fighting a restart issue, just changed fuel accumulator and its better. This purple wire might be that issue also!
