97 Expediton, 4300 Avital with DEI 556u Bypass

I have a 97 expedition im trying to install a avital 4300 in here is what i have please correct anything if it is wrong and do i need a 451m relay module i also have the dei 556u bypass module.

Primary harness H1

armed output   orange to ground
light flash    white to brown at switch
remote start activation       white/blue to blue on the 556u
dome light    optional?       black/white to ?
door trigger -green to blue/white
multiplex    needed?          blue to
door trigger + needed?       violet to
ground        black to ground
empty
siren +     brown to + of siren
2 channel validity        red/white to ?

auxiliary harness H2

factory disarm              light green/black to dark green/purple
factory rearmgreen/white to ?
programmable channel 4      necessary?
programmable channel 5      necessary?
wait to startnecessary?
second unlock output        necessary?

door lock harness 3 pin

green to   pink/lt green
blue to   pink/yellow
I'm having a hard time finding these only can find them at the switch.


remote start ribbon

output primary ignition pink to blue/green
high current 12v        red to other yellow
output to secondary ignition           pink/white to black/green
high current            red/white   don't cut

the car does have a 3rd ignition labeled as to transmission   do i need this?

remote start harness   H3

2nd status rear defogger              blue/white to necessary? blue on 556u ?
hood pin switch        grey to hood pin switch
brake shutdown        brown to light green at top of brake pedal
tach    violet/white to necessary?

12v constant            red to yellow or other 12constant
status input            blue to white/blue   on primary harness
true ignition input     pink to ?
ground   black to ground
key sense input +       violet to ?
key sense input   -     green to ?

or would it be better to use the alternate wiring and the 3 wire plug.


thank you in advance for any assistance.

Does the truck have Factory Remote Keyless Entry? no = need 451M
Does the truck have a chipped key? yes = need 556UW

Soldering is fun!

high current   red/white to light green/purple

where is the green/purple wired located    

thank you

It should be at the main ignition switch harness. Typical Ford trucks have several Yellow and
Light Green/Purple wires there that will test as +12V constant. Always verify and test with a
Digital Multi Meter before making any wire connections. If you find multiple +12V constant wires
at the ignition switch, it is best to split the Viper R/S load between them.

Thank you for your quick response so when i wire up the relay for the 3rd ignition the car behaves as if the key is in the ign in the acc position. As in car stereo is on power windows work without key in ignition. And on the 556u bypass is that all the wiring i need or do i need to use the ring as well?

The 556U is controlled by the R/S system to turn ON during R/S run time. A working key is placed inside the 556U, in a coil the reads the chip. The 556U's antenna wire is run up to the ignition cylinder and placed in a position to radiate the chip info sent to it from the 556U to the cars antenna, as if a key and chip were in the cylinder. So, yes, the 556U antenna must be used and located properly on the ignition cylinder.
