As some of you guys might know I have a 6.2 L86 Takeout with 6L80 trans that I bought for my 2014 Silverado 5.3 swap. Well I have decided to install it into a Geo Tracker that I got for free and it's in really really good shape. Anyway has anyone on here or know someone that has used Speartech for a new plug and play or reworked stock harness good or bad experiences welcome.

I looked at Speartech but went with PSI as the exact same setup I needed for what I am doing ( LS376-480 crate and 4L60E) was quite a but cheaper. Unfortunately I see PSI does not make a harness for you so that lessens your choices...

 

I used them on both of my trucks,had good luck, and good quality
