Hey lads

I was just turning over my new motor and have a bunch of codes relating the new 90mm LS2 throttle body. I have the wire adapter to covert it and have look at the connections, re-seated, etc and all looks fine. Any thoughts?

thx

Apparently this could be because of the Adapter harness I am using being wire wrong...any one have the schematics on the se Casper conversion cables ?

Its the Silver LS2 My issue looks to be resolved. The brown and yellow wire were swapped in the Caspers Harness. Everyone be sure to check this !!!

^ I had a issue with a harness a little while back. Im impatient lol and summit has them to me next day so instead of troubleshooting the harness lie you, i called summit while i was in the engine bay and ordered another one lol. After the car was up and going, and i wasnt going to get frustrated, i looked the harness over and on of the wires was just so slightly pulled free from the connector, but still in the pigtails, very weird.
