Hello all!!. Need Some HELP!!!! I have a four wire 02 senser and a auto meter a/f ratio guage that i want to hook up in my 72 ford f100. With that beeing said there is no ECU. The auto meter guage has three wires off of it one black,one red and one violet. The 02 senser has four wires one gray,two white,one black. There has got to be a way to hook this up?? I may need to get a diferant 02 senser and that is not a problem i just need to know what to do. SO any help would be nice.

Thank you all
