Soft Close Trunk Retrofit NOT Possible
 

Just for the record, since there isn't much info on this anywhere..

I pulled the servo lock, big rubber bump stop, and GM3 (general) module off a junk car to try to retrofit soft close to my 4.6is. As it turns out, the wiring harness is not the same, and there are 2 wires for the soft close that don't exist on the pre-facelift models.

These wires are part of the car's main wiring harness and run all the way up to the general module behind the glove box. So unless you want to rip your whole car apart for the soft close feature, then it's not going to work.

Disappointing, but putting it out there for anyone else who is thinking of trying.

Just more FYI:

I want to do it.
Anyone done it?
Need part numbers or pictures for what's needed.
GM3 module is not hard to find.

me to i wont it i have added springs so it auto opens on the press of the button , but now i wont the auto close , so jcorreanyc you saying the wires are there in a facelift but not in a preface lift as mine is a facelift do you have pics of the bits you pulled.

If you have a facelift then you already have the soft-close actuator.

so we talking about if you dont shut it fully and it pulls itself in shut , rather than it closing from fully open.

Correct... the soft-close function works only to lock the hatch without slamming it.

No E53 ever had the fully electric open/close tailgate. You could possible retro-fit such a feature but I've not seen anyone do it.

Something like this might work... https://www.autoease.com/product/liftgate/

i love how he ties to look cool back kicking the car to shut the tailgate in the promo video :rofl::rofl:

Looks really nice. I emailed them. They emailed back saying it doesn't fir X5 2002 :(

Unless of course your 17 year old daughter doesn't understand the concept of "just set it down honey, it will pull itself closed" - "SLAM!!!!" - anyway... :(
