Ok so im in the process of swapping from a ls1 intake to an ls6 intake. Well when i finally got the intake off i some how pulled the two wires out of the connector going FROM the main engine harness TO the knock sensor harness. Does anyone know how i should go about fixing this?? thanks.

 

You can get the new harness for around $30 from the dealer I believe. Mine did the same thing when I swapped, but my wires were brittle looking so I figured why not.

 

Thanks for the reply. How did you wire the wiring back into the main harness?

 

^^^ditto on the replacment harness at any GM Dealer^^^^^

Connector diagram attached.

 

my wiring harness looked like poop...........should have changed it out.......but it was a sunday...and my car is a DD....now i have codes for the knock sensors
