Samuelx Posted May 14, 2017 Share Posted May 14, 2017 Hi All, Awhile back, I installed a Denali split sound bomb and added some additional running lights. In order to get switched on power for the relays, I tapped into the positive tail light wire (brown/black wire). I cut the wire, added some connectors with an extra post, and then connected the relays to the post. Shortly afterwards, of course, I found that there is a 3 prong connector just a little ways up the wire from where I had cut (DOH!). Being that I still have some more electrical accessories that I'm planning on adding (extra brake light and maybe some driving lights), I'm going to do what I would have done from the get go if I had just done a little more planning/researching (so I wouldn't have had to permanently modify/damage OEM wiring). I got some Sumitomo connectors from this website: http://www.cycleterminal.com/hx-series.html and am going to add an extra section of wiring with easy access posts. Note that there are two versions of this connector - one with a wide "snap lock" and one with a narrow one - I ordered the wide one. Here is the connector (just following the wiring from the tail light towards the gas tank): Here is the new section I'm going to put in: FWIW, I've never been a fan of the snap lock style splice connectors - I've always felt that using those would sever a few of the strands of the wire I was tapping into. So, if you're OCD/quirky/stupid about that like me, adding a fresh section of wiring might be a reasonable alternative... Link to comment Share on other sites More sharing options...

Member Contributer Rectaltronics Posted May 14, 2017 Member Contributer Share Posted May 14, 2017 If I were to tap into OEM wiring I'd go for Posi-Lock stuff instead of those snap-on connectors you describe. If you're just a sunny day rider far from any oceans it doesn't matter as much but I'm also a big proponent of using marine -grade wiring and crimp connectors. The hookup wires use finer gauge strands that hold up better to vibration, and are tinned for weather resistance. The connectors include heat-shrink tubing that is coated inside with weather sealing material. Also give some thought to making sure that all the wiring is tied down or tie-wrapped sufficiently to keep vibration down. Link to comment Share on other sites More sharing options...

Have spent countless hours repairing other folks goofs when they have decided to work on their bike using them. Is yours a std us model or the dlx? If it's the dlx then there is a plug you can plug into. On your new piece of wiring I would strongly suggest you put some insulation around the piggy backs as they will pop a fuse if you touch something. A double bullet connector would have been a safer bet. Link to comment Share on other sites More sharing options...
Samuelx Posted May 14, 2017 Author Share Posted May 14, 2017 Thanks RT and Fink! Yes DLX and I actually have a question about the accessory plug - gonna start a new thread in a bit asking for help. Yes, definitely will insulate! Link to comment Share on other sites More sharing options...
