I need a pigtail or adapter harness to change an LS1 style map plug to the GM 12592525 style-it has a little larger male conns in it-the 12592525 fits in my LS3 intake-I already have a 2 bar there, I think, but I am using the Holley HP EFI and they have a dropdown to use the GM #
the one I have now I don't know the specs on
