I am doing an LS 6.0 with a Richmond 6 speed in my 67 Camaro. I Need some feedback from those who have used aftermarket wiring harnesses. Not necessarily which is best, but rather what you have used and how they turned out for ease of install, how well made, how happy you are with the product and support, etc. Thanks for your input in advance!

I highly recommend using Modern Vintage Systems. 317 224-6689 John is a great guy with exc quality and cust service. He will rework a stock harness or build one from scratch. Will build the harness to your specs. I have used him for years, and probably 7 or 8 harnesses.

I used speartech on my ls2, harness was perfect,car fired right up, and his customer service and tech support is top notch!

I'll check these out.... Completely rewiring my second gen during the swap and restoration. Thanks for these.

i got one from street n performance when I swapped from a v6 to a v8 in my firebird. The made the VCM connector section longer so I could put the computer inside the car. Been on the car for almost 8 years now with no issues. Easy install and everything was well labeled.

My father in law rebuilds hot rods and he has been using a lot of PSI harness's as of late for LS swaps, and thats likely who I will go with when I put a ls3 in my 71 camaro.
