Fast wiring harness help needed

[bloibl]

Guys I have a 67 Nova that we are replacing a wiring harness in. We purchased the Fast system and the biggest issue we are running into is what to do with all of the extra wire?????? It's driving me crazy I can't fit it under the dash with the AC system.

I am at the mercy of the board. Does anyone have suggestion what to do with all of this extra FK wire!!!!! can I buy a termination kit and do it my self??
