    newbie swap question

    I have an 87 C10 I'm wanting to do an LS swap. I'm wanting to do a 6.0 with 4l60e. is there an aftermarket harness to achieve this? I'm new to LS. or is there a donor vehicle I can find with this combination. also I'd like it to be DBW.

    Nelson performance will have the harness you will need. Get a tune from them as well so your setup will work.

    You could also use a stock harness. The modifications aren't hard to do. There is info on the site as to how to do them. I've done several and can help answer questions as they come up.

    Correct me if I am wrong, but couldn't you just use a harness from a vehicle with a 5.3l/ 4l60e? I didn't think there were any harness differences between the 5.3l and 6.0l?

    Just build your own, it's super easy. Lots of videos on YouTube about it also. You can also extend your wires and hide your pcm wherever you want

    very few donors with that combo, SS p/u, Cadillac Escalade but they were AWD, best bet if your going to do harness yourself would be get 6.0L motor, then buy wiring harness, computer, for a 5.3/4L60E, with the trans, but you will still need computer flashed for 6.0l motor. Just depends on how much you want to tackle.
