Will this work on a 2008 Silverado?

I used it on a older truck but it did have the electronic throttle body so as long as your original harness is for a 4l60e I wouldn’t see why this wouldn’t work but you do have to run the wires for the extra speed sensor because the 4l80e has two speed sensors not just one like the 4l60e.

Cheap junk

Harness was advertised as “plug and play” but was only so after I had to de pin the connectors, re wire it and then it worked. Caused issues and confusion when I first tried to drive with p0758 and p1810 codes. After spending hours researching wiring diagrams, I found more than half of the wires were misplaced. Cheap Chinese garbage. If I wanted to de pin connectors I would’ve just used my factory harness connector. What a waste of time and money. This trash company should stop selling altogether before they mess up someone else’s vehicle.

Did not work

Main harness for trans adapting did not work, threw all kinds of codes. Unplugged it, repinned factory connector and all issues went away. Parts sat too long in prep of swap to return, in the trash it goes. $43 for a 2 pin connector was definitely not worth it
