Hoping someone can help me out. I'm chasing the cold start injection (P1252) on my 97 Jetta and while I was looking over my wiring I noticed this particular plug was looking a little frayed. On closer inspection there's a black wire that was further down into harness that looks like it was cut. I'm assuming it's a ground (and hopefully the ground that's causing my issue) but I'm hoping someone can confirm it for me. It's the brown plug right above the big round plug on the side of the block. I couldn't find any other end that it might have been connected to.
