What cables will I need to hook into the GS2 SF1 signal to run my Insight with Direct Command Strip Till this fall in a 8430 auto trac ready tractor? No one at the local dealers seem to know what is needed.  I found the link below to a post about it, but wtf, is it really that complicated?  Thanks for the help! Ben
