I have a 6.0 that im installing in a 93 chevy and when i bought the engine the harness was cut, It was cut on the rear right side of the intake. its about 19 wires...dont see a MAF plug, transmission plug, vss, or 02 sensor plugs.
can anyone help me out here and tell me what these wires go to.

kind of a double post, its in my intro but figured it belonged here.
anyone???:(
I'd recommend using a volt meter and looping the wire to the PCM connector and marking each wire from there. It will take about 15-20 minutes but you'll know for sure where each wire goes.
to complicated, im lazy. besides dont have a wiring diagram.
figured some one here would know what it goes to, i guess i'll just have to go to a dealer and look under the hood of a used ls truck.
We can help you with wiring diagrams but if you'd rather look at another vehicle go for it.
You're up sh!t creek without a paddle unless you're willing to help yourself a little. NITROUS knows his wiring and I can help too but we need help from you to help you, dude.
Too lazy? Wanna buy fuel for travel or a plane ticket for someone that can help?
Let us know.
lol, just pushin buttons to get a response.:LOL:
Yeah i need a wiring diagram, pretty good with reading em too.I've heard ls engines are pretty easy to wire yourself. so i've read anyway.
Before i get into this harness i have a question. Will the ecm i have work with an older 4l60e (93 rwd)
the ecm and engine came out of a 2002 2500 series 4x4
dont know if the connectors or wiring would be the same as an 4l80 or 60.
done see why they would be different connectors
you are gonna need to get a pcm pinout for the truck the motor came out of and trace those wire back to the pcm and see which pins they go to and go from there.
i have pretty much a whole harness at the shop so whatever plugs u need i prolly gotem
4L60 and 4L80 have the same connector just a different pinout. Also the 80 has a second VSSQuote:

so should i be searching for another harness, and ecm if i want to run a old 4l60e. Would an ls1 with a 4l60e harness/ ecm work?
the ecm i have is for a 4x4, guessing 4l80
see how many wire go in the trans plug, then let me know and ill see how many are on mine, if its for an 80e i believe it has 2 less wires
there are 19 total wires in that bundle. Dont know how many of those are for the trans. Im guessing 5 for the MAF, then that leaves 14 wires.
how many wires do the 02 sensors use, are they 3 wire sensors???
and is there an extension for the rear 02's or are they still part of the whole harness?
thanks for the help
o2 sensors have 4 wires i believe on these trucks
The fbody/ls1 harness will be a lot of work to use on a truck setup.
why's that? wouldn't it be the same, actually easier to wire in electric fans...You have more experience, so i would trust your opinion better...just curious.Quote:

I am using the stock intake manifold and accessories, I can solder the old connectors from the 6.0 harness to an ls1 harness.
Are there any other connectors that are different other than injectors.
I have a pcm, serv # is 12586242, am i able to use this since my 6.0 is cable and not fly
MAP most likely, maybe have to change out the alt connector. I'm installing a LS1 style aftermarket harness to a 5.3L right now and its all going good but I'm not too sure what a factory harness would consist of change-wise to work on the truck engine. The PCM should work but if you're getting a tune anyway, trade up for a 411 PCM. The Fbody PCM program has the benefit of being able control both fans independantly with multiple speeds.
cool, i know i keep asking this question but, will that pcm or one that ran a 4l60e in a fbody run my old 4l60e???
Are those the last numbers on the pcm,411?
yeah, its the last three numbers of the part number on the PCM. Your PCM is going to need tuned no matter what, at least to turn off the VATS, rear 02s and various smog option such as the fuel vapor solenoid, plus tuning for tire sizes, gears and anything else that is different than stock. I'm not sure but there shouldn't be any reason it can't run the old 60e. I don't think it will last long though.
yeah i figured get rid of all the emission crap and vats, just wanted to make sure it was possible.
I did a search and found people using the lt1 4l60e on the ls1, so im assuming it works.
Oh and yeah i know it wont hold very long, but just wanna get it rolling for now. I only have a 90 day warranty on the engine and want to hear it run and make sure i have gook oil psi.
