has anyone used their wiring adapter harness they make for LS1 installs..or if there has been anyone that has had some experience with them???

 

Did you try searching for speartech???? There are tons of people that use them, and will give insight to the customer service and quality of parts. Do a search on here, then go do a search on LS1tech.com. Which is where you should be looking around anyway if you are doing an LS1 swap. Tons of posts that will mention speartech...

Edit...So I dont come across as a total you know what, I will tell you that John at Speartech is a great guy to deal with. Their harness is great. I didnt use one...I made my own. But I did call and speak with John and even though I wasnt a customer he still took time to help me out. You wont hear any complaints about speartech...

 

ya i hear ya..sorry about that...what i have in mind is a 5.3 engine out of a truck with maybe my 700r4 behind it if its possible..otherwise the 4L60E..and ive got a tbi car.and dont wanna hassle with the wiring ya know just plug and play!

 

Go with the 4L60E, send the harness to Dana at LT1350.com he does awesome work and labels everything to where it is basically plug and play.
