dude your plug wire routing looks killer! looks like you have TTI headers? do you mind showing me how you ran your # 5-7 and 4-6 wires? i want to run mine similiar to how you have yours but they will lay right across the pipes.
This is what I used from Summit. I installed this on the water pump. The A/C wire on the relay was ran to a switch on my shifter to turn on/off manually.
