What we have found when there is an issue with running lights but not other lights when installing the Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit # RM-15267 is that the problem is almost always due to an issue with the diodes. So if the wires are not properly routed with the diodes, or there is an issue where a wire was somehow crimped or damaged then the running lights would not work.

You need to create a jumper wire and attach the diodes that way, which may have been the problem so you should check to make sure you have your diodes properly installed.

I have added a link to a help article on installing diodes on a dinghy with combined wiring that I recommend taking a look at.I have also added a link to a video install of the wiring kit on a Jeep Wrangler for you to check out.
