My car has the early blue/ yellow wire instead of the red/ white at the TTS.
Someone has spliced the blue/yellow TTS into the red/ white at the CSV.

As i understand, the blue / yellow wire on the blue bulkhead connector (pin 24) should be wired to the TTS blue/ yellow, and the starter blue/yellow. Mine only goes to the starter.

Will this affect the circuit? Should i unsplice the TTS back to the blue connector?

My TTS may be ok , not exactly sure.
Between the 2 connections is 75 ohm, hot or cold.
Pin 1 to earth is 75 ohm.
Pin 2 to earth 0.5 ohm.
When heated they both go open/ to infinity.
Any help appreciated, going to try and fix the wires tomorrow.

When the TTS is COLD one of the pins should show continuity to ground while the other pin should show about 30 ohms. Does yours do that? If not, it's either hot (open to ground) or burned out.

Sorry I don't know what to tell you about the wiring.
