1G sensor grounds together? sensor 12v together?

[compression]

Specifically CAS 12v and injector resistor 12v , and TPS ground with coolant temp sensor ground?

Can I tie them together? I've added 1 large plug to separate the wire-harness for my relocation and I want to condense wires.

The TPS and numerous other sensors on the car are only 5v. You need to keep your 5v sensor grounds separate from the 12v sensor grounds... .

Correct, bit i believe those are both 5v , I was referring to the pin on the ecu , "sensors ground" I assume since they both need to go there it would be ok to connect them, I just wanted to Make sure the ground wasnt like a trigger or something on one of them.
