How do I convert it to a 1 ICS system though, if the clip is gone? I'm assuming I also have to repair this broken wire too?ICS will be a single wire on the Aftermarket carb. Hook that to the Green wire that went to the old two-wire ICS (should get 12V on the green wire with key on/engine off).
Yes, one-wire ICS is grounded through the carb body.
The Vacuum switch for decleration won't function now because it uses switched ground to function (through the emissions computer), with the two-wire ICS, which is no longer there.
Sell the switch if it's working; they're NLA.
Forgive my lack of bananas.
