I dunno about a wire, but folks with the 87-90 Renix (non-HO) 4 liter motors one can install a high-altitude CPS.

I think it advances the timing a bit...

Pretty sure it's a Jeep dealer only item...the ones out in the Rockies or Sierras may stock them, I would have to special order one out here in the flatlands.
