So without knowing _exactly_ what the EVS I upgrade included, I ordered it anyway. :-) At least I knew it had a shock sensor, which is good enough for me right now. In case anyone else is wondering what the kit includes, here's a picture of it unboxed. :-)



So in the box, you have (generally going clockwise):

- A 4-door installation manual addendum, the original installation manual (includes courtesy light stuff, which most people don't have), and a user manual to configure the unit (sensitivity, horn sound, etc.).

- The unit itself, with two fuses and a cover.

- A hood switch (labeled as a Ford part).

- A relay for the horn.

- Some extra wiring.

- The harness.

- Window stickers and a little flashing light for the dash.

Here are a few observations...

The hood switch appears to switch a ground when the hood is open. This ground wire is passed through the firewall and connects to the white harness wire ("Door Trigger Connection" on passenger side). So I'm guessing that when the hood is opened, it looks to the unit like the passenger side door was opened - I guess.

In the harness, there are two wires going to the passenger side lock/unlock, two going to the driver side lock/unlock, one going to the driver side parking light wire, and another one going through the firewall for the horn relay.

The horn relay wiring leads me to conclude that the wire coming from the EVS I harness is a ground. It provides a ground to the relay, which then switches the 12V from the battery. This 12V wire is connected to horn wire under the TIPM module.

So the two wires going through the firewall -- hood switch and horn trigger -- are both grounds.

Since my horns are located in front of my radiator, I'll probably mount an additional horn under the hood, exclusively for the EVS I. That way I won't have to splice into a wire under the TIPM module.

Hey JS

Why not go the other way and get car alarm w/t all the bells and whistles

I got a viper 5900 w/t
Shock , hood , tailgate car starter and motion detector and instantly notifies
Me if it goes of or even if just the warning goes off

 

Also has door un/lock and shows what happened

 

No need. All I wanted was to upgrade the alarm system with a shock sensor.

I might add a radar unit and window break later on. They're about $10 on eBay.

I also installed this setup some time ago and like it. Did not find a need for the hood switch (which is not mentioned in the manual) as the shock sensor is sufficient to trip upon any hood movement.

 

let me know how you like it

ive been pondering the idea of installing this on my Rubi as well
