I Love this instruction. I drove about three months with the needle of my fuelmeter on zero. I hated this. My volvogarage repared this problem three times and still after one year the problem came back. I never heard a clear explanation from the garage about the cause. Now I know. In my case TWO wires were broken.
Watch out when you solder, the plastic housing tends to melt when you heat the connector where the wire fits in.
Thankyou Thankyou Thankyou!!!!!!!!!!
