Flat tow lights for towing my Goblin

    Here is how I did my flat tow lights for towing my Goblin. My motorhome has had problems in the past with driving incandescent lights. Incandescent lights draw up to 10 times the current when they are initially turned on as the filaments are cold. They would blow out some circuit board in the motorhome. I switched all the motorhome running/tail lights - there were 13 of them - from incandescent to LEDs several years ago and have not since had any problems (after previously blowing out 2 circuit boards). I did not wan this to re-occur so the LED tail lights on the Goblin were great. I also will have a high mounted center stop light. If you have a cruise control you will need to add a resistor so the BCM thinks a light is working otherwise the cruise control will not work I am told. Where the resistor is in the circuit will not matter. If I ever get cruise control (my car did not come with it) I would mount the resistor right near the BCM so the current would not travle through my small gauge wires.

    I thought this sounded strange that you'd need the Center High Mounted Stop Lamp (CHMSL) for cruise control to work so as an exercise, I thought I'd trace it out. Keep in mind this is from an '09 service manual. It appears that the light blue wire splits two ways after it leaves the fuse box on the X2 connector. One goes to the CHMSL and one to the ECM. These circuits are in parallel so you "should" be able to remove the stop light input without affecting the ECM input.

    Actually, can my previous post be moved? I think the "Discuss the first stage instructions" would be the more appropriate place?
