New LS Standalone Harness - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Its a blue/red harness so its set for the early stuff on 411 pcms. Thats probably why its got the "DBC only" note. Wiring and connector need to be modded to work on the blue/green (late 02+) ECM's but will lack DBW control. If your using a cable setup, then be aware that some of the later GenIII Ecm's lacked IAC control to to DBC.

I may also be missing it, but in the pics it appears there is only a single ISS on the harness, meaning its setup for a 4l60e.

MFG doesn't show wire type either. TXL? GXL? Non rated? You have to be cautious with longevity of cheap wiring. Ask anyone who's bought an imported trailer lol.

I ordered for an LM7 with drive by cable and a 4l60e. My old harness was so brittle that taking the chance on this is worth it to me. Worse case is I have to buy a new year or two.

I know this is an older post, but any ecu that is capable of DBC can also do DBW . It's the Late DBW units that may not have Dbc circuitry
