the jumper wire goes to the egr temp sensor on the harness if i remember correctly, its a 2 pin connector. youll probably need to clear the code as well , you can just disconnect the battery for that
Didn't need to use the BBs or the block off bolt as I pulled everything (the kit is designed to leave all egr components in place, but obviously you don't need to...) @theglobb the connector in the kit goes into the one that you showed in your last pic. No codes after installing it.
