  Hello Dave,

  Thank you for writing.

  I have attached a link to the Ford Mobile Radio Installation Guidelines:
  http://www.fordemc.com/docs/download/Mobile_Radio_Guide.pdf that should help
  you with your mobile installation and ignition noise reduction. The RFI
  Suppression Beads may help with your ignition noise. Often it is the fuel
  injectors that cause the ticking interference and beads have helped in some
  cases. Also, the coil or spark unit maybe treated with beads. Each case is
  different, so you will need to do some experimenting on mobile noise
  suppression. Bonding the engine and the hood to the frame with tinned copper
  braids may also help.

  The DX Engineering RFI Suppression Ferrite Snap Beads were designed to offer
  the best coverage of the high frequency range. They come in 2 split-ferrite
  halves, in plastic case. So you can clamp them on any cable assembly. We
  have various sizes available for different cable diameters:
  &SecID=152&DeptID=42. Larger sizes are capable of taking multiple turns of
  the wire or cable. Each doubling of the turns of wire through the snap bead
  increases the interference suppression by a factor of 4. However, it may be
  that in your situation, you need more than one bead per line.

  We appreciate your interest in our products!

  I am very interested in learning how using SNAP-ON Ferrite Beads will
  eliminate ignition noise in the Ford Sport Trac truck I drive. Where would
  I install the ferrite beads?
