If you still have same problem with new ign sw it indicates that in spite of cutup/spliced wires ign kill side of safety sw's is still connected to kill circuit to eng and that possible orig problem still present.You have two choices.
1-get into a full blown troubleshooting job of checking operation of safety sw's & associated wiring for shorts/shorts to chassis.As a quickie check BEFORE disconnecting any sw's/wiring,check seat sw operation with an ohmmeter(connector for sw disconnected from sw),if there is a jumper in seat sw connector remove same,seat sw is start of ign kill circuit for safety sw's,a bad seat sw or jumper in connector for same will send signal to eng nobody sitting on seat,kill eng ign when cranking eng,seat sw functions same way as ign sw in stop/off position,completeing ground to ign kill circuit.
2-if you don't want to be bothered with troubleshooting/flustration of same & can live without safety sw's,then remove blue wire from connector where you did before as it is apparent that connector is after/downstream of safety sw connection into ign kill circuit.Disconnect tractor wiring harness where it connects to eng wiring,with ohmmeter go between blue wire in connector at eng end of tractor wiring harness connector & blue wire you removed from connector & mateing blue wire still in connector,on one of these wires you will get a 0 ohm reading,splice/butt splice a new wire to wire you got 0 ohm reading on long enough to get to ign sw,reconnect tractor wiring harness to eng,at ign sw locate blue wire in plug connector for sw & confirm that it goes to magneto(M)terminal at sw,if it does seperate blue wire from rest of wires in plug as far back as possible & cut,take end of new wire you added to ign module lead & slice/butt splice to short blue wire tail in ign sw connector,this now bypasses all safety sw's in ign kill circuit.

Today's Featured Article - Oil Bath Air Filters - by Chris Pratt. Some of us grew up thinking that an air filter was a paper thing that allowed air to pass while trapping dirt particles of a particles of a certain size. What a surprise to open up your first old tractor's air filter case and find a can that appears to be filled with the scrap metal swept from around a machine shop metal lathe. To top that off, you have a cup with oil in it ("why would you want to lubricate your carburetor?"). On closer examination (and some reading in a AC D-14 service manual), I found out that this is a pretty ingenious method of cleaning the air in the tractor's intake tract.
