i need help sending new wires from my vss to my ecu i know that B10 is my signal but i dont know where to send the other 2 wires power/ground? my ecu is an obd1 p28 and my engine harness, sombody removed my vss wires reasons unknown just trying to get everything back to normal thanks.

 

BLK/YEL ---> 12v Ignition
BLK ---> Ground
BLU/WHT ---> signal out (goes to ecu and/or speedometer)


Edit: Your signal wire may be orange.
