2010 ford fusion, viper 5901

Hi guys. I have a Viper 5901  I am installing it in a 2010 Ford Fusion. I have found a good spot to mount the main unit and thought I'd start with the Heavy gauge remote start (H3) 10 pin wiring harness first. The Viper harness diagram is as follows for the harness:                                                                                                            o H3/1 Pink (+) Ignition 1 Input / Output 

o H3/2 RED / Wh (+) Fused 30A Ignition 2  / Flex relay input 87

o H3/3 Orange (+) Accessory Output

o H3/4 Violet (+) Starter Output  (harness side of starter kill wire)

o H3/5 Green (+) Starter Input (key side of starter kill wire)

o H3/6 Red (+) Fused 30A Ignition 1 Input

o H3/7 Pink/Wh (+) Ignition 2 / Flex relay output

o H3/8 Pink/Blk (+) Flex Relay Input  87A key side (if required) of flex relayo H3/9 RED / Blk (+) Fused 30A Accessory / starter inputo H3/10             N/C       not usedThe Fusions ignition switch harness has a 7 pin plug. There are 6 wires in the 7 pin plug. The wiring diagram shows what 5 of them are. I'm not sure of the sixth.    Here is the fusion wiring diagram: 

	Battery		BLUE/RED		(+)		IGNITION SWITCH HARNESS
	Ignition 1		WHITE/ ORANGE		(+)		IGNITION SWITCH HARNESS
	Accessory 1		VIOLET/GREEN		(+)		IGNITION SWITCH HARNESS
	Starter 1		BLUE/WHITE		(+)		IGNITION SWITCH HARNESS
	Anti-Theft Type		FORD PATS® OR SECURILOCK® VEHICLE IMMOBILIZER
	Anti-Theft Descript		THE KEY SENDS AN RF SIGNAL TO THE BCM MODULE THROUGH AN ANTENNA LOCATED AROUND THE IGNITION CYLINDER
	Key Sense		BLUE/GRAY		(+)		IGNITION SWITCH HARNESS

I have tested and verified the function of the wires on the ignition harness. I'm still trying to figure out what the sixth wire is. The terminology that Viper uses is a little confusing to me and I am hoping you guys can steer me as to which wires from the H3 go to which wires on the ignition harness. Have no idea what a flex relay 87 is for. I believe I have to cut the Blue/White starter wire and use the Violet and Green wire from the H3 on it. I'm not certain on which accessory wire to use on the H3. I will run a wire from the battery for 12 volts if that is the best method. Hope to hear from you soon!

Oh, I forgot to mention I can't believe how small the wire gauge is on the Fusion ignition harness. I have installed two Bulldog systems years ago and the wires were a lot bigger on those cars. The Vipers harness wires look twice as thick!

I have tested the unlisted wire in the diagram.2010 Fusion- Ignition Harness-7 pin plug - pin number 3 is 12 volts constant. It appears to be grey with a brown or possibly black stripe. Don't know why its not in the diagram. Still hoping to hear from you guys on the wire connections on the H3 harness. Thanks

Thanks Chev. I didn't think to check it after changing gears. Sure enough, 12 volts when in park, 0 in the others. I would have thought that it would show 12 volts in neutral also, but it doesn't. It will start in neutral though.

OK. Since I haven't gotten any responses on the remote start heavy gauge wiring, here is what I am thinking is correct. If you guys could, does this sound correct to you.   Viper H3-1 Pink to Fusion pin-1 ignition 1 WHITE/ orange.......Viper H3-2 RED / White not used......... Viper H3-3 Orange to Fusion pin-6 accessory violet/green.......................Viper H3-4 Violet to Fusion starter side of cut wire pin-7 blue/white........................Viper H3-5 Green to Fusion key side.of cut wire pin-7 blue/white...............................Viper H3-6 Red to Fusion Battery or pin-4 blue/red...............H3-7 & H3-8 Pink/White - Pink/Black  not used................Viper H3-9 RED / Black to Fusion Battery or pin-4 blue/red.......................This is how I see it. If any of you guys with install experience see it different please let me know. I'm probablt going to start my wiring this weekend. I thought I would post my progress and installation pics as I go along to possibly help someone else doing a Fusion / Milan. Thanks in advance.

Afterthought:  I think that even though the car has an immobilizer, If I cut the starter wire and wire up both sides of it, it would prevent someone from starting the vehicle even if they have the key, IF the alarm was activated. Still probably won't wire it that way though. If they have my key they probably are going to have my remote too.
