Hello all, my name is Cole and I am having difficulty with a 4103 install on a 2004 Mercury Mountaineer. I have all wiring hooked up correctly (I believe) and verified with a volt meter. I am using a 556u bypass with a dealer coded and cut key placed inside. The vehicle start fine using the ignition, but does nothing when the remote start button is pressed. I currently have the brake wire switch hooked up correctly, the hood switch and neutral safety switch are both grounded, and the following wiring is hooked up as listed below:

Vehicle Battery Positive Wire (+): Yellow connected to H2/4 and H2/6 red wires

Vehicle Ignition Wire (+): RED / Green connected to H2/1 pink wire

Vehicle Accessory Wire (+): GREEN/ Light Green connected to H2/3 orange wire and H2/5 pink/white wire

Automobile Engine Starter Wire (+): Red Connected to H2/2 purple wire

Car Key Sense Wire (-): GREEN/ Violet not connected

Car Neutral Safety Wire (+): WHITE/ Red currently run to ground

Car Tachometer Wire (-): Pink/White connected to H3/2 violet/white tach wire

Car Speed Sense Wire: Gray/Black   not connected

Car Parking Lights Wire (+): Brown   connected correctly

Car Horn Wire (-): Yellow/Light Green    connected correctly

Satellite harness 4 pin connector; blue status output wire to blue 556u bypass wire

hood pin switch wire connected to ground

also normal grounds are hooked up correctly

The strange thing is that when i ground the H1/4 blue/white input activation wire the vehicle still doesn't crank, or even send voltage down the purple wire connected to the vehicle starter wire.

i don't have either + or - keysense wire hooked up as from what I have read it is not needed. I also don't have the pink wire from the 556u bypass hooked up ( +ignition input)


What do i do with the H1/3 wire that is listed as "+ignition out to alarm"? not sure its needed or where it goes.

Thanks in advance for any help, just to clarify after a long message... the remote fobs lock/unlock the doors, but the vehicle will not crank with the fob or the input wire grounded???

Also, after not getting anywhere after 8 hours of checking and rechecking, I did try another 4103 brain and bypass module just to make sure mine werent bad out of the box... no change at all.

Remove the gray hood wire from ground. If it's grounded it thinks the hood is open and won't start.
