Viper 5806V, 2011 Ford Crown Victoria

Not sure what is going on.   For the Viper to be outputting power constantly on it's Violet Starter wire is strange and the issue. First let's review the Viper and its' connections. 1. The Viper has four fused Power input wires. All of these wires need to get +12V constant power. I would connect two of them to each one of the C.V's Light Green/Violet wires at the main ignition switch harness. Remember that the Viper description of these +12V supply wires in the 10 Pin harness pertains to what it supplies, not to where it should be connected. 2. Your C.V. has one Ignition wire. It is Violet/Orange. The Viper thick Pink wire is the only wire that should be connected to this wire. 3. The C.V. has two Accessory wires. One is ACC1 and is Gray/Yellow*. The ACC2 wire is White/Violet. The thick Viper Orange wire gets connected to the Gray/Yellow wire. The thick Pink/White** Viper wire goes to the White/Violet wire. Again, these are the only wires connected to the C.V.'s Accessory wires. * Please note that there are two Gray/Yellow wires in the main ignition switch harness.    One is ACC1 and the other is Keysense. The Keysense wire will show +12V when a    key is inserted into the ignition switch and 0V when the key is removed/not present. ** Default Viper programming has this wire output set to IGN2. Change the Viper programming for this Flex Relay to Accessory and mentioned previously 4. The C.V.'s Dark Green Starter wire is cut. As noted, the Viper thick Violet wire goes to the vehicle side of the harness and the Viper thick Green goes to the ignition switch side of the cut wire. Again, these are the only Viper wire connection made to this vehicle wire. As stated several times, only the thick Vipers wires in the 10 Pin harness and the fused Red Input power wire in the 6 Pin harness are connect to the C.V.'s main ignition harness. None of the thin wires in the 24 Pin harness are connected to the C.V's main ignition switch harness (even if the Viper name sounds good). These thin "ignition" wires are all (-) signals used to control relays and are never directly connected to a vehicle (+) ignition wire. Additionally, if these (-) wires were connected to a (+) vehicle ignition wire, it could damage your Viper and cause the problem you are now experiencing. While not previously mentioned, here is the Viper 6 Pin harness connections. 1 RED (+)12VDC CONSTANT INPUT              to C.V.

thanks, just in case I have another viper 'brain' on the way but in the mean time went back over my install, particularly given the revelation that the install guide is describing what the viper is supplying on that pin (rather than as I had been viewing it, what the viper needed to connect to). this seems to have turned some of my connections against me though so I'm going to try and clarify with a new description of what I'm finding as regards the 10 pin connector since my car is a police p7b model, it has no smart key / chipped system and only 1 ignition circuit. for the vehicle's ignition wiring this is what I show with the DMM: wire color: key out/key in: ACC1: Run WHI/Vio        -     -     .....   12v   12v    LG/V #1        12v / 12v:     12v   12v LG/V #2        12v / 12v:     12v   12v Gry/Ylw (thick) -   / -     .. (.9mv) 12v Gry/Ylw (thin) -   / 12v:     12v   12v Viol/Org        -   /(126mv) (134mv) 12v The reason I post that after double checking is that if pin 5 (red) supplies 12v ignition 1 input, then I shouldn't have it hooked to a LG/V wire (is that correct?). It seems that it should possibly be spliced to Viol/Org as the "ignition 1" circuit (*instead of the thick pink wire, pin 10).    Unless this is not correct and pin 5 doesn't supply 12 volt it instead needs to connect to 12 volt constant (in which case LG/V would be a source of 12v constant). I know I'm confusing this and making it worse than it needs to be ... but is it accurate to change the wiring for the 10 pin to the following: 1. no connection 2. red/black - ?   (per the install, this supplies 12v accessory/starter input 3. not used (flex relay input) 4. pink/white - white/violet (*change viper programming as per previous instruction) 5. red - ? as above, since this supplies 12v ignition input ... change to V/OG "ignition 1" circuit? 6. green - key side/starter wire 7. violet - car side/starter wire 8. orange - 'thick' GY/YLW vehicle wire (*however, my DMM shows that this wire has no 12v in the first position (ACC) for the key - only the thinner GY/YLW wire has power in that position) 9. red/white - ? supplies 12v input, ignition 2 flex relay (so if it supplies that, shouldn't be connected to the current LG/V circuit) 10. pink - supplies ignition 1 input/output ? I'll understand if you give up on me ... i'm about to give up on myself but really want to understand this thing!    And finally, thank you to all who sacrificed on this Memorial day - the service members, their friends, family, and our great Nation.   Thank you Grandpa 2011 Crown Vic Police P7B

OK, let's go over the Viper 10 Pin R/S harness in detail. Remote Start, White 10-pin heavy gauge connector 1 No Connection 2 RED/BLACK (+) FUSED 12V ACCESSORY/STARTER INPUT The above wire needs to be connected to a vehicle wire that can supply it +12V constant. It in turn is used to supply the Vipers ACC1 and Starter wire outputs. The easy way to tell that it is an input wire is the protective fuse it has inline.   For your C.V. application this wire should be connected to one of the Lt. Green/Violet wires. 3 PINK/BLACK (+) IGNITION 2 pin 87a ( programmable - follows Pink/White setting ) This wire is used on very few applications. Typically on a vehicle that needs ignition switch isolation on the Pink/White wire connection during a R/S. Your C.V. doesn't need it. Some Nissans do. 4 PINK/WHITE (+) IGNITION 2 / ACCESSORY2 This wire is also known as the Flex Relay Output due to the fact that it is a programable output that can be an IGN or ACC wire, depending on Viper programming. For your C.V., program the Viper Flex Relay to ACC and connect this wire to the White/Violet wire in the C.V.'s main ignition harness. 5 RED (+) FUSED 12V IGNITION 1 INPUT This is another +12V constant fused input wire. It supplies the Vipers' Pink IGN wire output. It needs to be connected to one of the C.V.'s Lt. Green/Violet wires. 6 GREEN (+) STARTER INPUT (KEY SIDE) This wire is used in conjunction with the Vipers Violet Starter output wire to provide some selectable features like Starter Kill and Anti-Grind. If used, the vehicles main Starter wire is cut and this Green wire is connected to that cut Starter wire on the side coming from the key switch. The Vipers internal Starter relay is a basic 5-Wire SPDT relay and this is Pin 87a. During normal vehicle operation the vehicles Starter wire goes thru the N.C. pins on the internal Starter relay, in Pin 87a and out Pin 30, and everything is normal. When in use, the Viper controller can energize the Starter relay, opening the Pin 87a to Pin 30 connection, preventing a key Start signal from reaching the vehicles Starter circuit. 7 VIOLET (+) STARTER OUTPUT (CAR SIDE) This wire outputs a Starter signal ( +12V ) to the vehicle Starter wire to allow a R/S. It can be used in conjunction with the Vipers Green wire to add additional features. With your C.V. application, it is connected to the Dark Green wire at the main ignition switch harness ( if using the Green wire, this Violet wire gets connected to the vehicle/starter side of the cut vehicle Starter wire ).     8 ORANGE (+) ACCESSORY OUTPUT This is a Viper output wire that supplies the ACC1 vehicle circuit. For your C.V. application connect this wire to the C.V. thick Gray/Yellow wire.      9 RED/WHITE (+) FUSED 12V IGNITION 2 This is another +12V constant fused input wire. It supplies the Vipers' Pink/White flex relay wire output. It needs to be connected to one of the C.V.'s Lt. Green/Violet wires. 10 PINK (+) IGNITION 1 INPUT/OUTPUT This is another deceptive wire due to it's Viper description. Basically is it an output wire that is connected to the vehicles IGN1 wire. It has a double function as an input wire that the Viper monitors for theft purposes and possibly Tach programming. I.E. if this wire goes to +12V while the Viper alarm is armed, the Viper will energize the Starter Kill relay ( if programed and the Green wire is in use ) and turn on the siren. This Viper wire gets connected to the C.V's Violet/Orange Ignition1 wire. The Vipers R/S circuits are just 4 internal relays, Starter, IGN1, ACC1, Flex. Their Pin 30 outputs are Violet, Pink, Orange and Pink/White, respectively. The Pin 87 supply for these Viper outputs are Red/Black, Red, Red/Black and Red/White, respectively. As you can see the Red/Black +12V input wire supplies both the Starter and the ACC1 outputs but not to worry. This circuit will not get overloaded due to the fact that ACC drops to 0V while the Starter circuit goes to +12V ( during cranking ) just like the vehicle circuits work. Also notice that any Viper Red or Red/xxx wire with an inline fuse gets connected to a proper +12V constant source.Soldering is fun!

I installed the new brain, still had the seal strip over the 6 pin terminal and looks new. The blue LED is constant on, which seems to mean it’s in valet mode (?).    Since it’s new I don’t have any remotes paired to it yet. I tried to cancel valet mode using the ignition on/door open and press the control button but doesn’t work.   I’ll be doing more research At least it isn’t running immediately and still trying to start … but right now it doesn’t do anything except display a solid blue led I have gotten it to indicate garage mode on and off (based on the 9 short and 9 long parking light flashes) so I’m hopeful this brain is working2011 Crown Vic Police P7B

Well the door open- lock/unlock/ lock didn’t do it…. Sigh2011 Crown Vic Police P7B
