Bill,
    its a matter of wiring up a double pole double throw switch. theres 
nothing special about the later ECU's versus the early ECU's in this 
regard.  One pole of the DPDT triggers the injector, the other pole does 
the cold start function. You could retrofit this feature with a new 
switch and one extra wire run.
