I'm gathering all the parts for a 411 pcm transplant into my 1989 K1500- this is not a LS swap. Currently running a 7747 based EBL with port mod, 385 TPI with 700r4. 24x reluctor from EFI Connection installed and will be using vortec distributer for cam timing. Question is more wiring related regarding AC controls (ecu commanded or separate controller in dash), 700r4 lockup options and VSS type, guages. Have the 411 pcm and truck harness in hand to mod or have you purchased a harness that worked out well- I'm talking to a vender on thirdgen (I don't know how close our wiring is to the f-bodies of this era).
