Ok so I'm 95% complete with remaking my engine wiring harness, I know which sensors get grounded at the left shock tower connector, but I need to know which sensors are grounded at the thermostat and whether or not the grounds coming out of the left shock tower 14 pin connector from the ecu also get grounded there. Unfortunately I can't go by the old harness the wires were broke at the ground connector.

What chassis are you working on ?

 

93 del sol s with a 1995 b18c1 gsr engine

 

All yellow/black wires on the left shock tower are 12v... NOT grounds.
