S10 swap

[Programmer]

Thanks Al,

Kinda wondering which PCM to choose for the retrofit. I know I'll have to repin everything, and the ignition system could get a little dicey--Any input is always appreciated...

Lyndon.

  Lyndon, the 95 S10 4.3 Blazer with the VCM has a very different wiring 
  harness from the 7427 PCM vehicle. If your truck is auto equipped, getting a 
  harness and PCM from a donor vehicle is the way to go. Everything will fit 
  and your tranny will still shift. The distributor and ignition system are 
  also different. The VCM has a crank trigger on the timing cover and uses a 
  "High voltage switch" back there instead of a dizzy.
