Wiring for early GTI system

[roccodingo]

OK, the power going from the ign switch ( 50) to the starter solenoid (50) has a take off, going to the cold start valve, and in parallel to the thermo time switch. ( shown as red with black trace ), this allows power to warm up the thermo time switch bi metallic strip,

The other side of the cold start valve goes to earth via the thermo time switch..ie when the time switch has sufficiently warmed up, then it breaks the earth flow for the cold start valve.. ( from memory something like 5 or 8 seconds..)

HTH, ..

Good to hear you dropped in on Bill, how is he going working for himself ??, its a big move..
