[Diy_efi] Mystery ignition component

[Jeff Behrens]

Yes.  Does anybody know where to get the schematic for
how it hooks into the ecm?  I put a 1989 throttle body
injection setup onto my 91 Z71 and the middle two
wires were different between the two connectors.  I
just want to make sure it wont be a problem.
