    Lambda Relay Socket Wires

    Can someone help me out and show me what wires go into the lambda relay socket? Mine is not used due to EFI, but after cutting it out, my fuel pump no longer works (no power to fuel pump relay but power to fuse 7). I am wondering if two wires were joined at one of the lambda sockets and I broke that connection when I cut it out. Thanks in advance!

    I think I remember the brown power wire going to the lambda relay before going to the RPM relay but that's just a vivid memory.

    Two wires do meet on one of the terminals in the lambda socket and one of those wires goes to fuse 7. Mystery solved.
