Have 68 C10 doing LS swap. Have engine harness and ecm from 06 Tahoe. Salvage cut up harness. Was non flex harness. Bought replacement harness. From 05 1500 but turned out was flex fuel. Question is, can I use flex harness and ecm by replacing pigtails from old harness. Wire colors on both harnesses same. Assume I'd use flex ecm. Any ideas. Thanks for any help!
