After consulting with the owner of the saw, a new Stihl ignition module 0000 400 1300 was purchased. FYI the price of that module was $79.11 pre tax from a local Stihl dealer. The new module is bare bones see photo. No connection instructions. The IPL for an 029 that uses this module shows a wiring harness (see diagram), which this old 028 never had. The kill switch wire (orange highlighted) can be reused and I can make that separate ground wire (red highlighted). I can make the blue highlighted spaghetti too. However I don't know where I would connect that open ended spade socket (see blue ?). I'd appreciate info on where to connect that open ended spade socket. Is it even needed for this cross fit onto this old 028, which had a points-condenser ignition? A photo or diagram would really help sort out the open ended spade socket puzzler. The last photo shows this existing odd connection on this 028 that seems to be linking the handle section to the main chassis. Will that connection need to remain as is? Might that open ended spade socket need to connect to it someway somehow?
