Avital 4105L and 2006 Ford Fusion

I need to tap into the expertise of this forum in a bad way. My son got an Avital 4105L for Christmas. We will be installing it in his 2006 Fusion. I've looked at the wiring diagram and done some Google research but am not ready to dive right in. He has a third key and I was thinking a 556U bypass would be cost effective and do the job. I really would be profoundly grateful if I could get enough help/advice on this post to help me get the job done without taking his car out of service for more than a day. I have never installed a remote start so I'm a newbie. I did some basic electronics in the Air Force many years ago, have a certain amount of common sense, perseverance, but lack the knowledge to give me the confidence to dive in without leaning on someone more experienced. Please spare no detail...D Hall

OK, here is the info... First, you want to check to see if the Fusion has the Factory Alarm system. There will be an additional wire connection to make if it does. Second, you should consider a bypass module in place of the 556U with a working key inside. A 556U goes for about $12. A Directed 1100F bypass module can be found on EBay for $20. It's a few more wires to run and some programming steps but it provides better security and more reliable cold weather remote starts. There are other bypass modules out there but the 1100F comes pre-loaded with firmware and very easy to program. Please remember that the 4105V is designed for vehicles with automatic transmissions and should never be installed in a vehicle with a manual transmission. For the actual installation, you should have a computer safe, 12V LED tester. A Digital Multi Meter will also work but requires some knowledge to setup and operate. You should locate and verify all the vehicle wires before making any connections. Next comes bench prep. This is where you pre-configure the 4105 and bypass module. All of the un-used wires can be cut short and bundled together, etc. This will make vehicle installation easier and much neater.

You will need two working, non-clone keys to program the bypass module to the car. On the 4105, besides setting the Parking Lights to (+) output, you should make these programming changes : Menu 1 Feature 1 to Option 2 for Horn beep confirmation. Menu 2 Feature 1 to Option 4 Tach for more reliable remote start operation. You will have to perform the Tach Learn process detailed in the 4105 guide. That's about it.Soldering is fun!

Thank you! I have a couple of questions. 1. Do I connect 2 VIOLET/WHITE TACHOMETER INPUT WIRE..........................NOT GRAY OR BLUE/WHITE AT ANY INJECTOR OR COIL if using the tach learn feature? If so, does this wire run through the firewall to access an injector or coil line? 2. Not sure about locating the Fusion transponder plug but Google should help me with that. Thanks again KregD Hall

Yes, if you are running in Tach Mode, you want to connect the 4105 Tach wire to a good Tach source. You will have to pass these wires through the firewall to get at the engine and the F.I.'s or Spark Plug Coil. You will have to run the Hood Pin wire through the same firewall hole. If you decide to obtain R/S +12V power directly from the battery, that will be the third wire heading through the firewall. As for the vehicles transponder plug, it is a part of the ignition switch. Here is an install guide for another brand / model of bypass module that has some detailed graphics on that area of the car :     http://cdn.fortin.ca/download/22301/evo-one_ig_reg_bi_for_b_22301.pdf          It is a 4 Pin connector. Soldering is fun!

KREG. My son and I got started on this project today. We located all of the wires and hope to finish up tomorrow if school is cancelled here (snow). I have two questions. from above: R/S 5 Pin 1. BLACK/WHITE (-) NEUTRAL SAFETY SWITCH INPUT........Chassis Ground through kit supplied switch (I do not see a supplied switch in the Avital kit. Am I missing or overlooking something? Can I just attach this wire to chassis ground since the car is an automatic or do I need to attach it to something else (such as emergency brake switch as stated in my instructions? 2. We can't locate the wire on the 4105 to connect the DEI 1100F Blue/White GWR wire to. The instructions above say to connect it to the 4105 Blue/White @ pin 4 of 4. There is no corresponding pin. There is a -200 mA status output on the Satellite harness which is blue. The instructions above also says to connect the DEI1100 Blue/White wire to the RS 5 pin Blue/White wire. Am I making a 3 wire connection and, if so, where is the "Blue/White pin 4 of 4 you're referring to? Please advise. DennisD Hall

1. If there is no switch included in the kit, you can connect the Black/White Neutral Safety wire directly to chassis ground ( if it's an Auto Trans vehicle ). 2. Sorry for the confusion with the GWR wire. The 1100F control input is called GWR. It goes to the 4105 output called (-) Status Output. If you are not using the Blue/White wire for a Defroster control, you can use it as Status Output. I suggested it that way because you are not using any other wires on the 4 Pin plug with the Blue Status Output and could omit that harness all together if you use the Blue/White wire as Status Output. Either one is OK, you don't need to use both.Soldering is fun!

Thank you for the info. All good except now I’m wondering if I should hook up the defrost wire. Any words of wisdom on how to accomplish that too?D Hall

It might be possible to add the rear defog to the install, however I have no info on the actual vehicle wire needed. Perhaps another forum member can chime in with this info. Either way, you could connect the 4015L's 4 Pin harness and use the Blue (-) Status for the 1100F and reserve the Blue/White wire for use with the Defog.Soldering is fun!

Im not sure if its the same but on the 09 its white/orange coming off the back of the EATC head. You would have to test to see if its a pulse or steady trigger.If i Can't Install it    I Don't need it   Joe

Agreed, white/orange pin 10 at the climate controls, or pin 16 at the smart junction box: http://www.revbase.com/BBBMotor/Wd/DownloadPdf?id=123356My ex once told me I have a perfect face for radio.
