September 28, 2013
I used this harness on my 68 Camaro. At first, I thought I would save time and money by re-working the original one from my donor Camaro. 3 Months later after trouble shooting nearly every day for trouble codes I decided to look for a harness at a reasonable price. I used this particular one and could not of been happier. Everything about it is perfect! It is very well made and I have been enjoying my car ever since. Do not make the mistake I did and try to save time and perhaps a little bit of money by attempting to create your own. The only regret I have in regards of my swap is not having read a review like this when I was planning out my swap. You will never regret going with this fine LS1 swap harness.
Pros:
  • it is wired for automatic as well as manual trans
Yes, I recommend this product.

All of the gagues in my swap are from Autometer. They are all electric and with the proper senders, they all plug right into the harness. Autometer costumer support will help you with selecting the the necessary senders as some gagues already come with them. The harness does come with prewired for manual and automatic tranny. Just tuck away which ever one you don't use.

This harness contains a signal wire for any programmable electric speedometer. The senders for the water temperature and oil pressure gauges should be installed directly into the block by making use of our sender adapter fittings, part numbers 1822277 & 1822268. This harness has all necessary wiring to make use of the 4L60e transmission.

NO, no ECM is included with the harness. Try Ebay or wrecking yard for the computer.
