Banks Dual Heater and Billet Heater Upgrade Kit Installation and Wiring Diagrams

INSTALL INSTRUCTIONS
Part #s 42807, 42809, & 42830

Banks Ram-Air® Intake System 2007.5-2024 Dodge/RAM 2500-5500 6.7L Diesel

Please read through the following instructions thoroughly before starting your installation. If you have any questions please visit our Support Page.

The following diagrams show the recommended wiring layout for connecting an additional coil heater to your dual heat-capable Monster-Ram or bolting on a Banks Billet Heater.

Your heating kit will include either a thick or thin red connecting wire, depending on which upgrade heater kit you’ve purchased. For clarity, these diagrams are color-coded as shown below.

Only one coil heater should ever be connected to the end of a thin gauge wire, and no more than two coil heaters should ever be connected to the end of the thick gauge wire.

Throttle Delete Accommodation

If the throttle valve has been deleted, the supplied M6 screws will likely be too long. For proper thread engagement into the Monster-Ram, you will need 43mm plus the thickness of the throttle delete flange.

M6 screws are typically sold in 5mm length increments. If your required length ends in a 3, round down. If it ends in a 4, round up. Use the equation below to determine the length of screws required.

Corrected Screw Specification

M6 x 1.0 x L
L = 43mm + T

Example

If: flange thickness T = 12mm
Length = 43mm + 12mm = 55 mm
New screw spec: M6 x 1.0 x 55mm

Quad Heater Coil Note: Installing four coil heaters may exceed the rated capability of the vehicle’s heater circuit. This is not a recommended configuration, and any such installation is undertaken at the owner’s risk.

Dual Heater In Banks Monster-Ram

+12V (From Relay/Solenoid) – 1st Heater

Thin Gauge Wire – 2rd Heater

Wire the 2nd heater in series after the 12V lead via the thin gauge wire.

Single Heater In Banks Monster-Ram + 1500W Billet Heater

+12V (From Relay/Solenoid) – 1st Heater

Thick Gauge Wire – 2nd Heater

Thin Gauge Wire – 3rd Heater

Wire the 2nd heater in series via the thick gauge wire, and the 3rd heater in series via the thin gauge wire.

Dual Heater In Banks Monster-Ram + 750W Billet Heater

+12V (From Relay/Solenoid) – 1st Heater

Thick Gauge Wire – 2nd Heater

Thin Gauge Wire – 3rd Heater

Wire the 2nd and 3rd heaters in parallel with one thin wire on top of the Monster-Ram, and the larger gauge wire to the Billet Heater.

Wiring the 2nd and 3rd heaters in series through the thin gauge wire will exceed the thin wire’s current rating.

Tri Heater In Banks Monster-Ram

+12V (From Relay/Solenoid) – 1st Heater

Thin Gauge Wire – 2nd Heater

Thin Gauge Wire – 3rd Heater

Wire the 2nd and 3rd heaters in parallel with their own thin gauge wires.

Wiring the 2nd and 3rd heaters in series will exceed the current rating for the first thin gauge wire.

Dual Heater In Banks Monster-Ram + 1500W Billet Heater

+12V (From Relay/Solenoid) – 1st Heater

Thick Gauge Wire – 2nd Heater

Thin Gauge Wire – 3rd Heater

Thin Gauge Wire – 4th Heater

Wire the 2nd heater with the thick gauge wire, and the 3rd heater in series with the thick gauge wire. The 4th heater is wired in parallel with the 1st heater by the thin wire.

Note: This arrangement draws a nominal current of 250 amps, which may exceed the rated capability of the vehicle’s heater circuit. We do not recommend this configuration and any such installation is undertaken at the owner’s risk.

Wiring all 4 heaters in series through the thin gauge wire will exceed the thin wire’s current rating.

Tri-Heater In Banks Monster-Ram + 1500W Billet Heater

Configuration Not Permitted

Using 5 heaters will exceed the factory electrical system’s capacity, overload the heater relay, damage the vehicle’s electrical system, and risk a fire. This is not a permitted configuration.
