Did a 2005 Sport Trac recently. Here is what I found :
There are four Red +12V constant 25 Amp wires at the ignition switch harness.
Starter = RED / Light Blue ( 16 gauge )
Ignition = Light GREEN/ Violet ( 12 gauge )
ACC = Gray / YELLOW, Brown and Pink/Black ( all 16 gauge )
Remote start 10 pin heavy gauge connector
H3 /1. Pink Ignition1 input/output Light GREEN/ Violet
H3/2 RED / white Fuse30a ignition2 flex relay Red #1
H3/3orange. Accessory out put Gray / YELLOW
H3/4 violet starter output RED / Light Blue Cut wire - car side
H3/5 green stater input RED / Light Blue Cut wire - ign switch side
H3/6 red. Fused 30 a. Ignition1 input Red #2
H3/7. Pink/white ignition 2 flex relay output Brown Set To ACC
H3/8pink/black flex relay input 87a Not Used
H3/9 RED / black. Fuse 30a accessory /stater input Red #3
Extra 30/40 Amp SPDT Relay for ACC3
Relay Pin 85 to Viper H2/22 ORANGE (-) 200mA ACCESSORY OUTPUT
Relay Pins 86 and 87 to Sport Trac Red #4 through 20 Amp fuse
Relay Pin 30 to Sport Trac Pink/Black

Soldering is fun!
H2/22 Orange (-) 200ma accessory out put to relay pin86. And pin87 to acc pink and black red #4 trough pin 30 correct

Well...
Assuming that your 30/40 Amp relay does not have internal coil quenching and you didn't want to follow standard
relay wiring conventions, you could connect the Vipers (-) ACC output to Relay Pin 86.
Assuming your removed Relay Pin 87A or completely insulated that wire, you could run the +12V supply wire to
Relay Pin 30. ( Also assuming you are using the more common SPDT relay suggested and not a SPST relay that
does not have a Pin 87A )
Finally, you have nothing connected to Relay Pin 85, so it won't work. You would have to connect a +12V constant
to Relay Pin 85 for it to output the +12V ACC signal you want on Pin 87 during a remote start.
Still like my suggestion ( which includes a fuse ) better, but it is your vehicle.

Almost...
85 h2/22orange(-)
86 12 volts red #4
87 acc sport track pink and black
30 12 volts red #4 through 20 Amp fuse
If relay has Pin 87A, ensure it is well insulated.

86 from ignition NOT constant and a 1N4004 diode across 85 and 86, band to 86.

Amateurs assume, don't test and have problems; pros test first. I am not a free install service.
Read the installation manual, do a search here or online for your vehicle wiring before posting.
