What is Simplest Magnetic Tow Bar Lighting Solution for Tow Vehicle that has 7-Way  

Good evening Jameson. Nice to hear from you....thanks for picking up my question. First - I actually like to "Heavy Duty" tow light set and wouldn't mind cutting of the 4-way connector and splicing back in the 7-pole (PK12706) if there are some specific instructions along with some diagrams or even better some video click with close-ups to follow so the splicing job would be almost "dummy proof". If that's not possible I will certainly be OK with purchasing the "Basic" tow light kit (PE26UR) along with the ease of using the 7 Pole to 4-way Adaptor (PK12716). Let me know ! Also, I do notice that the "Basic" tow light kit is only 20 ft. long. The 1991 YJ is about 12 ft. long which only leaves about 8 ft. to connect to the rear of the RV. Is that long enough for turns, etc so the connector won't pull out of the RV receiver ?! I'm gonna assume a design engineer already made all those calculations and ran a couple of practical demonstrations ?! Getting back to the Basic Tow kit.....does it come with its own storage box as does the Heavy Duty Kit ? Almost done....I hope you can look this up easily....When I recently bought the Tow Bar assembly for my YJ did it include the 2 safety chains? If not, Give me a couple of suggestions/options. I would rather get safety chains which are about 1.5 times the recommended strength....so if the specs for towing a '91 YJ call for (lets say) 5,000 ld. rated safety chains I think I'll get 7,000 lb. rated chains.....something like that. OK....I'm done for the night and I appreciate your time and energy !! Last question, if I get the Basic tow kit....do you sell the plastic sheeting/covering/casing that goes over/wraps around wiring for a little added protection from the elements? OK....that's it !! I appreciate you time and energy. David Hollis
