After doing many Hot Rod LS Swaps in the 2007-11 JK/JKUs and trying different power components, relay boxes and supply circuits, we have designed , what we beleive to be as close to a DROP IN power and control circuit wire harness system as we can. Remember the switched ignition circuits on the JK OS are CAN BUS controlled and do not energize until the CAN BUS system is 'woken up' through the Wireless Node Module. When you LS swap it, the WNM no longer triggers the IGN Circuits. This can cause issues and gremlins with your LS Swap.
The core of the POWERPLAY Harness is a compact, covered and weather resistant fuse and relay center, we call the PowerBox. The PowerBox mounts on a custom bracket in the battery tray. A protected single main power supply cable connects to the battery and powers the distribution center. From the heart of the PowerBox, the main harness runs across the engine bay over to the drivers side, splitting into 2 trunks, [1] going into the interior and the other [1] to the ECU tray.
On the POWERPLAY Harness, the cable run that terminates at the ECU Tray has connectors on the ends of the wire groups that will directly plug directly into you LS Engine harness if RED ROCK did your Stand Alone Harness Modifications. If you built your own Stand Alone with the help of our LS GUIDE BOOK Series on the swap, the mating connectors and terminals are supplied to make the connection.
The POWERPLAY Harness has circuit provisions for tying into your factory body harness to get all the indicator circuits and fuel sender signals into the tub and up to the dash. We install a connector on this trunk of the harness and the mating end has flying leads for each circuit for ease of installation.
The POWERPLAY Harness has (2) FAN Circuits that run from the ECU Connectors to the passenger side of the engine bay, If you are keeping the STOCK JK Fan, you are going to use our WeatherProof High Amp Relay Kit to run the LOW Speed function of the fan. For the HIGH Speed function, FAN 2 Circuit will tie into the activation trigger line for the HIGH SPEED FAN Relay.
Included with the POWERPLAY Harness System are wire and connector diagrams to show you where to splice into the factory JK harnesses to get the necessary circuit signals.
The Standard POWERPLAY Interior Harness has 25 wires that pass through the firewall. These wires include circuits include for everything you need for reliable a LS Swap and to connect to your gauges.
Interior Wiring Circuits:
- ECU Signal Circuits- Speedometer, Tachometer, MIL Light, Terminated Serial Data
- Gauge Circuits- Oil Pressure, Water Temp
- Cruise Control Circuits- Set/Accel, Resume/Coast, On/Off
- AC Request, Brake Light, Terminated Key Start, Ignition Relay Trigger
- Chassis/Dash Indicator Tie In Circuits- Left Turn, Right Turn, High Beam, Fog Light, Running Lights, Fuel Level
- Power Circuits- Fused 12v Switched and optional 12V Constant
- Locker Activation Circuits for Rubicon Editions
- [2] Extra Circuits.. that termiate at the battery tray... just cause a few extra wires always comes in handy sooner or later!
