ProStart CT-3300 - Trunk Unlock

Hi All,

Newbie here - this is a great looking site - I'm glad I found you.

I installed a ProStart CT-3300 yesterday on our '92 Pathfinder. All went relatively well until I tried installing the trunk unlock (the Pathfinder has a rear window that latches).

The signal wire from the ProStart module sends a negative pulse, while the vehicle swith is activated on a positive pulse. So thanks to your great site, I learned how to wire in a relay to reverse the pulse polarity. This worked GREAT, except that once I press the "trunk unlock" button on my remote, the negative pulse from the module seems to be continuous - keeping the latch open. In other words, I can't relatch the window until I go and pull the (-) signal wire off of the relay. If I then reattach it, the latch opens again. Once I've done this a few times, it seems the signal goes away, and all is well (until I hit the button again).

So does anyone have any ideas? I thought maybe the length of this pulse is programmable, but I can't find any instructions on this. Besides this little inconvenience, the install went pretty well.

Thanks for the help.

Are you using the trunk release wire or an AUX channel ?

Hi Jeff,

Yes, I'm using the trunk release wire from the module. According to the install guide, it sends a negative pulse.
