RT wiring to flat four quick fix?

[Telgren]

So I was looking at converting the Spyder 9 pin back to flat four and without doing an extreme amount of mods I did some thinking and using an IC type coverter, thinking this would work:

So if one does that, and then uses the RT plug, would this not solve the whole problem for about $30?

In general, piggybacked converters do not work. The Spyder already has a trailer module built into its connector, so to use the converter, you would have to tap in prior to the trailer module. Not sure why you would want one, anywway. The Spyder RT trailer modules after 2010 already have 4-wire output. You just need the connectors to match. The connector you have shown is the wrong side...same as the one on the Spyder. You need the one with the locking ring. You will also need the sockets (pins), the blank hole plugs, a rear boot, and the special crimping pliers. Doubt you'll get out of it for $30. That is why most folks just purchase the 2010 trailer tongue harness or the 2011/2012 trailer pole harness to wire to their trailer or make into an adapter.
