Installed an improved wireharness for headlights and foglights, routing battery power directly to the bulbs with 4 individual relays. Did the Marinco plug modification to bring out the block heater to an outlet in the front bumper. Simply plug in an extension cord. 3-Gauge A-pillar pod with EGT, Transmission temperature and Boost pressure. I can highly recommend www.dieselmanor.com. Their installation kit was super complete and the instructions were well illustrated and exquisitely detailed.
