Default trunk release

I am in the process of hooking up my keyless entry and after searching I see that the door locks require a positive pulse. Does the trunk release also require a positive pulse?

Yes, the trunk release is a positive trigger. Most units supply a negative output to use for that particular channel, so you'll almost certainly need to use a relay to invert the polarity to drive the circuit.

Grab a SPDT relay from any electronics store...

connect as followed...
terminal 86 to constant power
terminal 85 to the negative trunk release output of the brain
terminal 30 to the black/white wire connected to the trunk release button, usually found low in the driver'* kick panel area
terminal 87 also tied to constant power

Or since most of the stores have jacked their prices on relays...

Visit a local yard and collect a few for your projects.
