I have done an engine swap. I have a 1996 S10 2.2 automatic. I bought a complete 1994 truck running 2.2 manual. I used the 1996 wiring harness, but the 1994 coil pack. I don't have original 96 engine or coil pack. I was told the ignition modules are different. Can anybody tell me the difference? Also how many plug in to 1996 coil pack? Thanks Mike
