Right now I have my speed sensor on a separate ground from my reverse lockout solenoid... I want to add a temperature sensor wire but all 6 pins on my weatherpak connector are taken up. Can I tap the speed sense ground into my reverse solenoid ground to free up a spot on my connector? No interference issues?
 
Vss is grounded to ecu. It's actually hi and lo signal

The car was driving and working fine with my autometer speedo... One wire to ground, the other to the speedo. Both of my T56 cars are wired like this. Im just wondering if you think I may pick up any interference sharing a ground wire with the solenoid. I would think no since its just a square wave signal (right?), but Ive been wrong before :tomato:
 
Just to update this, I have the VSS sensor grounded with my reverse lockout solenoid and it works fine. No speedo spikes or anything odd when the solenoid is activated
