adding actucator to the trunk lock

I am not positive i understand what you are asking. Mainly if you are using an add on aftermarket solenoid that will require a high current 12v source. It is best to use just a single relay since more than likely the output from your remote start unit is low current. They are also usually negative outputs. Wire that like this Pin 85: Negative Output from remote start Pin 86: 12v Fused Pin 30: Positive input to solenoid Pin 87: 12v Fused Then the other side of the solenoid should go to ground. If the truck has a carpeted cover you can use one of the support structures inside the truck lid, but be sure any ground screws wont penetrate the outer sheet metal. If it is open simply run the ground along with the power wire down inside the truck and ground to the body somewhere out of site. Now if you are using an OEM release solenoid that only has a 1 wire input, it likely grounds itself via the mounting bolts and only the power wire should be run to it. The relay should still be used as shown above. Hope that helps! -James

The third section answered my question, so the oem solenoid, ground itself out? I already installed the relay

If the oEM solenoid has two wires, one will get grounded and the other to the relay...Mike M2

the oem solenoide has one wire input.

That is correct a 2 wire solenoid needs both run to it, a single wire solenoid grounds itself and only needs 12v to activate.

thanks for answering my question

take it off and bench test it.
