1. Radio installations in vehicles powered by liquefied petroleum gas must conform to the following requirements Radio installations in vehicles powered by liquefied petroleum gas with the LP gas container in the trunk or other sealed off space within the interior of the vehicle must conform to the National Fire Protection Association Standard NFPA 58 that requires that e The space containing radio equipment shall be isolated by a seal from the space containing the LP gas container and its fittings e Outside filling connections shall be used for the LP gas container e The LP gas container space shall be vented to the outside of the vehicle RUNNING CABLES To assure the feasibility of the cable routings you plan to use it is suggested that you run the cables before mounting the radio Be sure to leave some slack in each cable going to the radio so that the radio may be pulled out for servicing with the power applied Try to route the cables away from locations where they will be exposed to heat exhaust pipes mufflers tailpipes etc battery acid sharp edges or mechanical damage or where they will be a nuisance to automobile mechanics the driver or passengers Keep wiring away from electronic computer modules other electronic modules and ignition circuits to help prevent interference to these components and radio equipment In addition try to utilize existing holes in the firewall and trunk wall and the channels above or2. beneath the doors You may also use the channels through door and window columns where they are convenient for running cables unless you plan to install rigid or flexible conduit in which to run the cables POWER CABLE The Power Cable is supplied for negative ground systems only It consists of a fused red lead a black lead and a fused yellow lead ignition switch control To install the Power Cable run the red and black leads to the vehicle battery and the yellow lead to the ignition switch If an existing hole is not conveniently located on the driver s side firewall for the passage of the Power Cable through 5 the firewall drill a 5 8 inch hole and insert the rubber grommet provided If the battery is located on the passenger side of the vehicle the battery leads should cross the vehicle in front of the engine All attempts should be made to maintain as much distance as possible between the radio power lead and any vehicle electronic modules and wiring Be sure to keep these leads mounted so they cannot snag on any moving part of the engine Connect the red lead to the positive battery terminal and the black lead to the negative battery terminal Always locate the fuse as close to the battery as possible Coil up the surplus cable and secure it out of the way with the retaining strap provided Be sure to leave some slack in the cables going to the radio so that it may be pulled out for servicing with the power applied IG
