I Am Currently Building A Couple Sleds For Myself And Friend. First Off I Am Putting A 2000 800 Psi Bigblock Motor In 440 Iq Chassis. If I Am Running A 2000 Motor In A 2006 Chassis What Wire Harness Should I Use. Should I Use The Stock One On 2000 800 Motor? If So Headlight Were Different And So Are The Plug Inns. That Is Problem So Far. Any Advice. Also Convertin A 2004 440 Proxr Chassis To Fit 700 Bigblock And Have Same Problem With Wiring. Bassically Convertin New Chassis To Run With Slightly Older Motor And Need Wiring Tips. Thanks For Any Input.
