GM factory LS3 ecu and harness. What is it worth?

[markaaron80]

I bought a new factory GM 495hp LS3 crate motor. I have decided to go with a Holley Terminator X-Max. So I will not be using the ECU or harness. It's new and unused. What's it worth. Not trying to get top dollar, just a good fair price for it.


Thanks in advance.

New theyre like 1900 so id say 1300-1600 should be easy to get rid of

They are not worth it though. The wires are too long in some areas and short in others. For a Camaro, I had to cut and re-pin almost every wire to get a clean install. I would never pay $2k for it! The fuse box is from a Astro, just get one from the junkyard.

if I were to offer on this harness, $500…

The fuse box is from an Astro van, but just the shell. It is not pinned anything like the ls3 harness. So in other words, you couldn't pull one from a salvage yard and use it as is for your swap.

I beg to differ. Like I said, I re-wired a whole GM harness. I even added fan relays and other circuits to it.

So did I, but the average builder could not source the terminals and wire it up to use it/ modify it. Hence our business wiring custom cars.

I really like using this box for the compactness and versatility. And one of my cars has a terminator x.
