Also need about 10-15 ft of 18AWG wire and if you want an enclosure for it and
the flex tubing to
cover the wires for asthetics. Also you might want to add connectors in between
the circuit and
what connects to the car in case you want to pull it out for any reason.
RadioShack should have
everything needed but they are definately not the cheapest. Norvac by washington
square and maybe
FRY's or Wacky Willy's would be your best bet IMO. Depending on where you get
the stuff i would
estimate spending between $10 to $25, but even at $25 its way cheaper than
caspers or the others
going for around $100. All credit goes to BackInBlack on the ClubGP webpage for
coming up with
the original, i modified it according to how i built it with readily available
parts.
