    Relays are basically electrically-operated switches. Usually they have (4) wires. Sometimes 5.
    (2) of the wires would be the high current circuit, the other (2) wires are what activate the switch.
    Wire 1 = 12v high current into relay
    Wire 2 = 12v high current out of relay
    Wire 3 = 12 low current to activate relay (trigger wire)
    Wire 4 = ground to activate relay

    Most relays have a diagram on them that should describe the circuit and which legs do what.

    You "feel" the difference because you want to "feel" the difference. Since you just spent money on the upgrade you "have" to feel the difference

    I'm looking to eliminate the double pump process I have to follow right now to get the pedal hard

    See if the PCM isnít actually sending a ground signal instead of a positive to trigger the relay.

    Never heard of a 3 legged relay? Like stated a four or five.

    Only three things I can think of assuming the relay is in fact good. (Iím trusting you swapped with another)

    1) a 100% bad range selector switch or wiring from it to PCM. However Iíve never seen one fail in both neutral and park positions.

    2) a bad PCM but doubtful

    3) a broken ground in the starting circuitry.

    How many tabs are on the actual relay? It wouldnít be the first Iíve seen where the wiring came loose and dropped inside the fuse box. Iíve seen it at least twice on cooling fan relays that got a tad too warm.

    You could really use the help of alldatadyi.com and itís easy to navigate diagrams and definitely a powerprobe.
