Sales People (be careful!)::
Everyday, we get dozens of requests through
our chat & ticket support system, request for forum passwords,
questions on installation problems or questions. We can only focus on questions from our customers. The questions are simple..
the answers are simple - but these people, because they did not
buy from AUTOTOYS.COM cannot get an answer. Dont make a mistake
by buying through auctions, fly by night operations or new pop
up websites who are just a voice over the phone (a sales person)
with absolutely NO EXPERIENCE.
No experience installing in cars, no experience what-so-ever!
They barely know the products they sell! Don't make that mistake!
Make sure your purchase is from autotoys.com. These articles are
proof we know what we are doing and that we WORK IN CARS! We work on the newest cars with
the newest products.

Doorlocks in 2002+ Nissan Maxima, using a PAC TR7
If you are putting in an aftermarket alarm or keyless entry in any 2002+ Nissan Maxima, you may need a PAC Tr7 (found here for sale, or search under TR7 in our storefront)
OVERVIEW: Although most alarms have double pulse unlocking as an programming option, we have found through our installs that the timing on those double pulse unlocks are sometimes just too long. This vehicle requires a double unlock pulse to unlock the doors. The second pulse (negative) duration if too long will tell the car's cpu that you want to roll down the window. The doorlock system functions as UNLOCK then if a ground still exist (ie: key still in cylinder in unlock position), then the windows will start to roll down. What happens with some alarms which are wired directly with double unlock pulse turned on,t he doorlocks will unlock, but the extended ground pulse is read by the car incorrectly, hence the front windows roll down JUST SLIGHTLY. The customer has to ROLL BACK UP the windows each time they disarm/unlock the car with the aftermarket alarm or keyless entry. With the TR7, the pulsing can be adjusted, but we found it to be "JUST RIGHT" and it did the job without rolling down the windows. IT IS PERFECT. We highly recommend it for your alarm installation. |

Since the car uses molex plugs and wires need to go into the driver's door, one option is to run the wires on the outside.

This is where we mounted the LED for the car alarm. |

This is the PAC Tr7 unit we used. |
