749 with P/H - Third Generation F-Body Message Boards

Will change from 730ECM to p/h with a 749 and wonder if I got this right

1. Wire up the 749 like sy/ty
2. Change inj drivers and sense resistors
3. Add a "internal" jumper between C10-C14

Injectors connects to
1,3,5,7 to C11 and C12
2,4,6,8 to C10 and C14

jumper wires between D5-D6 and C13-C15

Edit.....
Also make sure to remove D7.......

I switched from -165ECM to -730ECM ($8D) and then to ($58) and then I did the p/h injector mods for the -749ECM and I didnt get the fueling to work properly so I checked all the wiring and found that I had to remove D7 from my ECM to get p/h to work correct, so now its only tuning left............
