Doing a MPFI swap on my 1990 Standard Hatch. I understand that C1 and C2 move to B10 and B12, but am curious as to what I do with the lead that's already occupying B12? There's a white/red wire in there and I can't find a)what it's for, or b)what to do with it. I've searched, but cannot find an answer. Can anyone help me? Thanks.

So it's entirely unnecessary for my application. Thank you for your help 4drEF.
