This is awesome!I have a Ford Ranger which doesn't have power windows/locks...etc. Many years I have been unlocking the truck with the key and it can be a total PITA if it's raining or one has their hands full. I can deal with manual windows, but keyless entry is almost a must. I found two door actuators in my "stuff" pile and decided I had enough and wanted to tackle putting in a keyless entry. There are MANY sites/forums that help you with wiring. So please don't let the bunch of wires scare you. For the cost of this unit it was a no brainer to do in my opinion. This is not hard to install.. It will probably take you longer to take apart your vehicle and mount the acutators, run the wires, solder everything and then test...etc..I wanted to use the progressive unlock feature. This means, I push the unlock button once, and it will unlock my driver's side door. Push the button again within 15 seconds and it will unlock my passenger side door. Since I have a truck and I drive it 99% of the time, I didn't want the passenger side to unlock everytime.This is how to wire it up accordingly: NOTE. You will need another relay to operate the second door actuator (passenger side)[B+ is the POSITIVE 12v source from the battery]H1/9 violet UNLOCK 87 = B+ Hot at all times (fused)H1/7 violet/blk LOCK 87 = B+ Hot at all times (fused)Hq1/17 brown/blk UNLOCK 87a = GROUNDH1/6 wht/blk LOCK 87a = GROUNDH1/8 blue/blk UNLOCK 30 = DRIVER actuator UNLOCK wireH1/5 grn/blk LOCK 30 = BOTH actuators LOCK wire(s)(obviously you will need the 12v constant,ignition, and ground, not depicted in the above diagram, as it's self explanatory via the manual)Now you need a relay for the PASSENGER UNLOCK (2nd unlock)30 = PASSENGER actuator UNLOCK wire87a = GROUND87 and 86 = B+ Hot at all times (fused)85 = 2101 H1/2 blue 2nd unlock wire.Hope the above helps as I searched a LOT for the progressive unlock feature and not a lot was coming up.I also ordered a small buzzer so now when I press unlock/lock it sounds of a chirp instead of the horn beeping. I found the horn beeping to be very annoying especially if you are getting into your car often or it's late at night.For the total cost of under $40 and I now have keyless entry on my truck I couldn't be happier! Mind you it might be a little more expensive depending on your door actuators and if you need to purchase, wire, relays..etc But if you are tackling this type of project you MOST likely already have the necessary items and supplies to complete the install.In summary:All I wanted was a way to unlock/lock my truck remotely. Avital is a quality brand! Great price. I now have progressive door locks. The unit chirps just as an OEM system would, and my parking lights flash just like OEM. The unit has many options including unlock when you shut the vehicle off (3 seconds) and lock when you turn the vehicle on (3 seconds). I'm ecstatic that I did this and even happier at the convenience of not fumbling with a key anymore.
