I'm not a big Avital user, but if the 5303 install guide I'm looking at is correct, the unit does not have built in lock relays and
it's a "push/pull" type output. That means external relays for the locks or a DEI 451M door lock module. The 451M kit
includes the required 1,200 ohm resistor. If you are using external relays, here is a link to the Bulldog diagram for the locks :

Not positive because there are other slight differences but if your Tribute has the Factory alarm system, you could try it
the way shown in this 2005 - 2007 Mariner Pictorial :
https://www.the12volt.com/installbay/forum_posts.asp?tid=135376You should place 1N4001 diodes in the 5303L's lock and unlock output wires due to their "push / Pull" type output, band
toward the 5303L.
Here is the Ignition wire harness ( looks the same as the Pictorial ) :
Heavy gauge relay satellite wiring diagram
H/1 PURPLE STARTER OUTPUT (STARTER SIDE) * TAN/LIGHT BLUE (+) @ IGNITION SWITCH HARNESS
H/2 GREEN STARTER INPUT (KEY SIDE) * TAN/LIGHT BLUE (+) @ IGNITION SWITCH HARNESS
H/3 RED (+) HIGH CURRENT 12V INPUT Connect to BATTERY
H/4 ORANGE OUTPUT TO ACC CIRCUIT BLACK/ LIGHT GREEN (+) @ IGNITION SWITCH HARNESS
H/5 PINK OUTPUT TO PRIMARY IGNITION CIRCUIT LIGHT GREEN/ PURPLE (+) @ IGNITION SWITCH HARNESS
H/6 RED (+) (30A) HIGH CURRENT 12V INPUT Connect to BATTERY
H/7 PINK/WHITE OUTPUT TO 2nd IGNITION CIRCUIT not used
H/8 RED / WHITE (+) (30A) HIGH CURRENT 12V INPUT Connect to BATTERY
* cut the Tan/Light Blue wire
These are thin wires but you can still use the 5303L's thick wires for the connections.
For the transponder bypass, the Pictorial shows the transponder plug location and the RX / TX wires. For the PKALL
here is the wiring :
PURPLE / White to Tribute RX wire Transponder Plug, Pin 4, RED / Black
Yellow/Black to Tribute TX wire Transponder Plug, Pin 3, BROWN / Orange
Blue/White to 5303L BLUE (-) 200 mA STATUS OUTPUT
Pink to 5303L thick Pink IGN1 output wire ( which goes to Tribute Light GREEN/ Purple wire )
Think you can get +12V and Ground using the 4 Pin D2D harness to the corresponding port on the 5303L.
Soldering is fun!
