Installing Avital remote start model 4115L on a 2006 Volvo XC90 for first time. Has anyone done this before and if so can shoot some pointers my way? Installation appears straight forward but need specifics on which wires to tap under the steering column,etc and also practical advice on bypassing the key/chip issue since I understand there is a key chip that must be in the ignition in order to start the vehicle. Thank you
Even though you are using a one button R/S system, I would use a bypass module that would handle the key wrap
bypass and also handle the locks, disarm, trunk release plus supply the Brake, Tach and Hood Status. It will make
your job easier. My choice would be an FLCAN flashed with the DBI-AL(DL)-VO firmware. This would allow D2D
communication between the 4115 and the FLCAN. You should be able to find a seller that will flash the FLCAN
for you prior to shipment for around $60. Here is a link to the install guide :

As for the rest of the wires here is a diagram of the main ignition connector :
Please note that Pin 3 is Keysense and mandatory. You can power it as IGN2 (+) but will need a relay.
And here is a diagram for the Parking Lights :
You will need four 3 Amp diodes to split the 4115's lone (+) Parking Light output. Make sure the 4115's
Parking Light jumper is set tp (+).

Soldering is fun!
Thank you so much for posting some advice......clearly I really need it!! Struggled all,weekend and still notHing to show for it.
Hopefully these pics will,come thru explaining what I’ve done so far .....but it ain’t working yet.
I read up on the d2d and it sounds like this makes all connections needed except the power and ground? Am I reading too much into that? As you’ll see I assumed many wires could be left out (for now) and that the thing would work as long as I didn’t lock the car and left the key in ignition or near ignition so it reads the chip and would not need an immobile bypassing device...
This is definitely not easy and I’m usually pretty good with stuff like this, or so I thought....but the directions suck. Terrible help from the manufacturer too...

Yep, those pic's are a bit hard to read. Just fill in the below list.
