Thank you for the info!I don't have a video but the black piece on the right will go onto the steering shaft with the original nut. Then the silver piece on the left will get bolted to first black piece. The remaining piece gets bolted to your steering wheel.
My NRG hub has an opening for the horn cable. I don't see one in the DF hub (black piece on right) so you'll probably have to add a hole for the cables if you want the horn to go through the quick connect.
Just went through your entire build and did not see how you did yours, what page is it on?My build thread shows how I did mine if you choose to use it.
