I want to hook up the cruise control in my 91 Z to the 93 ecm after an engine swap. The 91 ecm pulsed at 2000ppm and the 93 pulses at 4000ppm to both the speedo and the cruise module( 1 wire output).

1. can I just hook it up and the ccm will only use 2000ppm?

2. will I need a filter to halve the pulses from the ecm?

3. what can I use as a filter ?

Thanks for any info,

Dean
