Viper 4806V in 2006 Ford E350 24 pin harness

My first install - I'm a 20+ year mechanic and have no problem with wiring but some of the terms I'm not familiar with and could use some help. 2006 Ford E350, gas engine if it matters. Has factory keyless entry but no alarm. Some of the 24 pin harness I don't know if I need or not. Not using any of the aux outputs - only using the system to lock, unlock and start. 1 pnk/wht (-) 200mA Ignition 2/Flex OUTPUT *don't think I need this 2 blu/wht (-) 200mA 2nd status/rear defogger output *not used 3 RED / wht (-) 200mA Trunk release output *not used 4 blk/yel (-) 200mA Dome light output *undecided if I'll use 5 dk blue (-) 200mA Status output *dont think I need this 6 wht/blk (-) 200mA Aux 3 output *not used 7 wht/vio (-) 200mA Aux 1 output *not used 8 org/blk (-) 200mA Aux 4 output *not used 9 gray    (-) Hood pin input *used 10 blue        Factory horn input *not used 11 wht/blu     Activation input *??? 12 vio/wht     Tach input *#1 inj 13 blk/wht     (-) Neutral Safety/Parking br *grounded 14 grn/blk     Factory alarm disarm output *not used 15 green       (-) Door input *not used - automatic 16 empty 17 pink        (-) 200mA Ignition 1 output *do I need this? 18 violet      (+) door input *not used - automatic 19 vio/blk     (-) 200mA Aux 2 output *not used 20 brown       (+) brake shutdown *used 21 vio/yel     (-) 200mA starter output *do I need this? 22 gry/blk     (-) diesel wait *not used 23 orange      (-) 200mA Accessory output *not used 24 grn/wht     (-) 200mA Factory alarm output *not used The ignition and starter output are the ones I don't understand. Do these need to be hooked to anything for proper function? If I understand correctly, I do not - these are for triggering other functions or accessories. Thanks in advance for any assistance.

Your E350 does not have a PATS system. **** The Activation input is a way to initiate a R/S instead of using the R/S FOB's. Bulldog Security lists these ignition wires : 12 VOLT CONSTANT LIGHT GREEN/ PURPLE (+) @ IGNITION SWITCH HARNESS     STARTER WHITE/ PINK (+) @ IGNITION SWITCH HARNESS       IGNITION 1 PINK/LIGHT GREEN (+) @ IGNITION SWITCH HARNESS     IGNITION 2 BLACK/ LIGHT GREEN (+) @ IGNITION SWITCH HARNESS     ACCESSORY /HEATER BLOWER 1 GRAY / YELLOW (+) @ IGNITION SWITCH HARNESS     ACCESSORY /HEATER BLOWER 2 RED (+) @ IGNITION SWITCH HARNESS Test your ignition switch wires to see if it has the same setup. If there is an ACC2 wire, the Viper can not directly support it and you should never connect one R/S ignition output to two vehicle wires. The extra relay will keep these two ACC circuits isolated like the factory system. Relay wiring below : Relay Pin 85 to Viper Orange (-) 200mA Accessory output Relay Pins 86 and 87 to +12V constant through 20 Amp fuse Relay Pin 30 to E350 ACC2 RED (+) @ IGNITION SWITCH HARNESS Relay Pin 87a not used - insulate Soldering is fun!

Thank you very much. Do I need to hook up the ACC wires if I am not using any accessory outputs?Knows just enough to be dangerous

I believe that the thick Gray / YELLOW is needed for the heat / AC fan motor. Personally, I like to duplicate what the key does during a normal start up so I power both ACC circuits.Soldering is fun!

Good enough for me - I have relays standing by and will use them. Thanks again!Knows just enough to be dangerous

No red wire in the ignition switch harness, so no ACC2 I've gone into overthinking mode and now am doubting some of my other planned connections.

Soldering is fun!

Hopefully these are the last questions: I do not want the honk output - neighbor has that on the RS on his Camaro and it annoys me. Do I need to connect that for the RS to function? When you said split the load between the three light GREEN/ purple wires on the ign switch - (there are three), did you mean I should take pin 1 on the 8 pin harness and connect to all those three wires *or* use the other two light green / purple wires to power other 12v + constant inputs Thanks again and Happy New Year!Knows just enough to be dangerous

Horn is not mandatory at all. Can be a help with programming, etc. As in each Viper fused power input goes to a different vehicle +12V wire.
