1) Which cable caliber is the recommendable for connecting an Amperemeter Guage?? 2) An good voltage regulator??? 3) What kind of tape I need to use for protect/cover the cables against the heat in the motor section??? 4) How I could restore the plastic at side of rear seats, has something like depth scratches, please show the picture Thank you in advance.
O.K. on the first question it really depends on the length of the run of wire and load it will carry. Here is a chart that might help you.http://www.rbeelectronics.com/wtable.htm Any major name brand voltage regulator will work like Borg/Warner or a Motorcraft unit. No protection is necessary in the engine compartment as long as the wires are run away from hot items. A "wire loom" is nice because it gives some protection and dresses things up a little. The rear panels are a mystery to me and I won't give you any advice on them because I would be wrong.
