6.0L For Buggy

Guys i have found a LY6 motor for my buggy but it does not have the harness, ecm or the fly by wire stuff. It is at a salvage yard and they say the can fine another harness and every thing i need to do to swap. Will that work or is there a aftermarket harness and ecm and fly by wire stuff available. Thanks.

The drive by wire is easy to find.

Hit up the guys at turn key engine

They sell the harness and computer and can delete all the BS off of it that you may not want.
I have had a 6.0 in my last 2 rigs. Love it

The LY6 is a Gen IV motor and different from the earlier Gen III's. Make sure you get everything ECM and TCM if you have an auto trans. A reworked stock harness will be cheaper if they don't rape you on the prices. Most times its 500 bucks to rework them.

I would look at Speartech as well for a new harness if your going that route.

If you do rework your harness make sure you trust the guy who does it. I had the harness from my 8.1 reworked and it failed at the worst time going up the slabs on the rubicon at 2 am (when it started to snow). I tried everything I knew to try and couldn't track down the problem and had to be towed out of the con. Once we tore the entire harness apart it turned out to be the two wires on the crank sensor had been cut with a razor blade by the guy who reworked the harness and the two wires kept shorting out.

I had Pacific Fab make me a new harness and delete all unnessisary wires and fuses. I now run the entire truck on 3 relays and 6 fuses all mounted in a water tight panel on the dash. Plus they made me a color coded wire chart and where it goes so there will never be a question of what is powered of what fuse and what wires they are.

Hope this helps and doesn't scare you, but there is nothing worse than staring at a harness and not knowing what goes to what and what wires are abandon and what are live.

I'm hurt, you guys didn't even think about me for the harness/PCM/TCM stuff

LY6 is a VVT 6.0. Meaning you need another VVT harness. A 5.3 harness won't work.

...I'm sure I can locate all of the parts you need for a fraction of your cost (unless you have an in with the wrecking yards)....

Also, LY6 doesn't have a TAC module. So all you need is the harness, pedal and throttle body.

..You could also convert the LY6 from VVT if you wanted...And then you can use a 5.3, or whatever, harness.

Wayne, The newer 2009 or 10 and up 5.3L come with vvt as well.

You do harnesses as well or is that you buddy??

Go buy a harness, if you can, for a newer VVT 5.3 and see how much that fawker costs you! lol But 6.0/6.2 VVT's are more common, and should be cheaper. As well some of the connections probably won't match, namely the o2 sensors and the trans. The 5.3 will most likely have the 4l65 behind it, where the 6.0 will probably have the 6l80.

Yes, buddy does them, but it's still through me
