Need a DIY for genV LT4 standalone wire harness
 

I'm looking for a resource with info on converting a zo6, or ZL1 genV LT4 harness to standalone operation. Stock harnesses are cheap, and all the vendors want insane money for a harness with the emissions controls wireing included.

Is everyone buying aftermarket standalone engine harnesses for Gen V LT4 and LT1 swaps? I need to rework a oem Zo6 harness to run as a standalone unit with all emissions equipment equipment. I will be reffing this swap in California, and will post it up to help others in California in return for a little help. Thanks in advance.

I want to swap a GEN V LT1 engine in a 2007 C6 Corvette that has a 6L80E automatic transmission?

Is the swap doable with a C7 LT1 engine wiring harness?

Will the factory Speedo, tachometer, fuel gauge, temp gauge and other gauges work with a reworked factory GEN V LT1 wiring harness and PCM?

Thanks for help.

It might be better to start your own thread rather than hijacking this one.

Take a look Swap Time on YouTube. His name is Mitch and his website is https://www.swaptimeusa.com. I have been watching his videos for a while now and seems to have a good handle on the Gen 3,4 and 5 harnesses.

By the way, the guy I referenced in the previous post is in located in Las Vegas.

Check with Mitch from Swap Time on YouTube or his website https://www.swaptimeusa.com.

Thanks for the info. Going to check it out.

that guy has a few threads on here. I believe his member is vannatta20

Thanks. I contacted them through the website they have. Not a DIY guide, but it gets me in contact with someone who seems like they will be cool to work with on this project.

The modifications to the factory harness are surprisingly not too difficult. You'll want to get one of those generic 7 circuit fuse blocks for all of the key on power circuits. My l83 has been up and running for about a year now after I did it myself, and I'm no pro. I found a 2015 Silverado wiring diagram online and used that to know which wires to splice into.

Thanks for the input. I already ordered a 2017 Zo6 harness, ECM through Swaptime, and paid Swaptime to handle converting it over to stand alone. I will post up results. Probably just start a swap thread here to document the FR-S LT4 swap.

Yes please report out on the harness, finding solid suppliers of those seems to be hit and miss..

This is the oem unit Mitch at http://www.swaptimeusa.com will be converting over to standalone operation.

This is the reworked engine harness. I should be getting it soon. I still need to get all the other components for the fuel, and emission systems.
