so orinally had a 5.3 4l60 swap to go in the 91 shortbed. ddecided to use to use it for another project. ended up piecing together a 6.0 w harness computer dbw pedal from a 2009 express van. purchased my fuel sytem from race parts solutions, i decided i would go with -6 ptfe with a aeromotive 340 and EFI regulator and all the fittings and adapters for the factory rail. im ready to drop it in so far and measure drive shaft, install fuel system. still missing a radiator and fans as well as the WIRING! i ahve the express van harness and computer as well as the factory harness for the tbi 305. Does anyone have a link to how to wire this harness. i have found alot on 2007 and under but not to much about the newer harnesses. Im trying to retain the factory air and cruise control as well as the gauges. i have the harnesses stripped and cleaned ready to change and remove wires. Im trying to do this one myself to grasp a better idea of how the wiring works. thanks for any input and more pictures to come from the install. first LS swap for me but byfar not the last.
