Subject: Scytek Astra A15 into 2018 Nissan Versa
Date Posted: September 15, 2020 at 6:58 PM

I bought the Scytek Astra A15 alarm with remote start and keyless entry from eBay and there is no installation manual. I found a manual for a different Scytek Astra model. The wires seem to be the same... red, white, brown, blue w/white, white w/red, orange, brown w/white, black w/white, blue, gray, yellow, black, purple and green. Red goes to constant 12 volt power. White says, "Parking Light Output (+/-) relay. Connect the White w +12V or ground only when the parking lights are on and set the internal the proper polarity. For parking light circuits exceeding 10 amos, a relay independent left and right parking light circuits, diodes must be installed NOTE Do not connect the WHITE wire to the vehicle's headlight circuit."
I have a 2018 Nissan Versa sedan. I have no idea where to connect the white wire. I have no idea what polarity my parking lights are. In fact, I have no idea where to connect any of the wires except for the red one. I know how to connect that one to a constant power in my fuse box. Can someone please tell me where to connect the other wires? I'll attach screenshots of the other models wiring diagram. Thanks in advance!!!

I accidentally posted the wrong pic. I did buy 4 relays in case I need them for my power door lock upgrade. Here's the other wiring diagram. Thanks! posted_image

The White wire at Pin 2 of 14 can be set to either a (+) or (-) Parking Light Output via an internal jumper. Set the jumper to a (+) output for your Nissan Versa. It can handle a 10 Amp circuit, so no external relay will be required. You will directly connect it to the wire shown below after testing and verifying it with a Digital Multi Meter ( set to 20 V DC ).

Versa
Parking Lamp (+)   RED ( or Blue )   DRIVER KICK PANEL GRAY 16 PIN CONN, PIN 4
or
Versa Note
Parking Lamp (+)   RED   DRIVER KICK PANEL WHITE 24 PIN CONN, PIN 3

did you also buy a bypass module? I assume the 2018 nissan versa requires one.. (however being in the states, it's not law to have immobilizer)

I did not purchase a bypass module. I'm not really sure what it is or why I would need it. I'm a high voltage (Alternating Current) electrician. I can light up a whole city! I thought with my knowledge and experience this would be simple! This low voltage (Direct Current) has me baffled!!! I can use all the help I can get with this. Do I absolutely need a bypass module? Where would I need to put it? Or why do I need it? Thanks a million!!!

Hello!, Thanks for your help and your reply! As I stated in another reply, I'm a high voltage (Alternating Current) Electrician. I can light up a whole city! I thought this low voltage (Direct Current) would be easy. I've been proven wrong! I have a new respect for low voltage techs! So basically, I find a gray 16 pin connector in the area of the driver's kick panel. I then find pin 4 - I have a sedan (not a Note). Pin 4 should be red or blue. I test it with my multimeter set on 20v DC for polarity. If it's + I connect directly to pin 2 or pin 4? If my polarity is - then I use a jumper to change the polarity of pin 2?
I'm a little confused about pin 2's polarity cat be changed with a jumper, but it's pin 4 that I'm testing... What do I do if pin 4 tests negative? And what do I do if pin 4 tests positive?
I'm not trying to be a burden. I'm a fairly intelligent person that's a little confused. Thanks so much for your time and assistance!!!
Thanks!!!

Wait a minute...
You said Pin 2 of 14,
and then you said Pin 4 of a 16 pin connector...
Are the 14 and the 16 two different connectors?
Thanks!!!

Update:
I couldn't find a 14 pin connector in the driver's kick panel ("The White wire at Pin 2 of 14 can be set to either a (+) or (-) Parking Light Output via an internal jumper.").
I did find the 16 pin connector. I'm attaching 3 pictures. The first shows markings on the gray plastic. A #1 which I marked in red, a #8 that I marked in green and it also has an h4 marking that I labeled with blue. I think the h4 marking is insignificant. The second picture shows the other side with 7 and 16 embossed on the gray plastic. I labeled the 7 with blue and the 16 with red. The 3rd picture is going from the 1 marking to the 7 marking numbering each wire. If I'm correct, pin 4 is red with a silver dot. Is this the one I check for polarity? Or is this the one I splice into? Or both? Thanks a million!!! posted_image posted_image posted_image

depends if you want the car to start or not.. try this, wrap the head of the key in tin foil and see if it starts. If it does you don't need a bypass module.. if it doesn't you need one. I am 99% you will need one. Only cars that i can think of that don't have an immobilizer in the states is hyundia. (key start ones)

Sorry for the confusion. The 14 Pin connector I was referring to is the one on the Astra R/S unit with the White Parking Light output wire, not the Versa DKP.

From one of your photos, it looks like the Red wire at Pin 4 is the correct one. Just test it with your DMM. Should go to +12V when the Parking Lights are ON.

Oh... Ok!!!
I understand now...
Yes, the Astra's 14 pin has a red at 1 which goes to constant 12v power and the second pin (white) goes to the parking lights and can be pos + or neg -. This was half of my question... How to tell if I need positive or negative? And the second part is where do I connect it to? So if I put my digital multimeter on the red pin 4 of the Versa DKP and I get +12v, that's where I connect it? I cut that red wire, strip the 2 cut ends, join the white wire of pin 2 of the Astra and solder all 3 wires together?
Thank you for all your help!!!

To silvercivisir,

I'm still very confused!!! And I apologise for my ignorance. The alarm is not installed yet and the key fobs that come with the alarm/keyless entry/remote start isn't working yet. My car is a base model Nissan Versa. It has manual/standard transmission, manual door locks, hand cranks for the windows and regular keys to open the door and start the engine. I do not have a Nissan key fob for my car. Once the alarm is installed I'll have a Scytek Astra key fob. I bought power window actuators/motors and power door lock actuators. I'm going to install it all, but starting with the alarm and door lock actuators. I'm still curious about the bypass module. Being that I don't have a Nissan key fob, how else can I tell if I need the bypass module? What exactly is a bypass module for? What does it do? Where does it connect to? Thanks a million for your help!!!

As mentioned by Kreg, verify with your meter that this wire has 12 volts only when the parking lights are on. If so, you will use a positive output on your Scytek. You don't need to cut the factory wire, just strip it back enough that you can connect to it.

Wrap the head of your ignition key (not key fob) in several layers of aluminum foil and try to start the engine. It should fail to start. You may also notice a key icon flashing in the instrument cluster letting you know the car doesn't "see" the transponder. This is a factory anti-theft feature and is pretty standard on most newer vehicles.

The bypass module will allow the engine to start by replicating the signal the system receives when you start with a key. It does this one of two ways: either digitally through the vehicle's databus wires, or by using another programmed key and running a loop of wire around the end of the ignition switch. The second option usually involves placing a key inside the bypass module, although you can make your own with some wire, a relay and a diode.

You can check the websites of the three main manufacturers of said bypass modules to hopefully get a better understanding:

https://directechs.com/
https://fortin.ca/
https://www.idatalink.com/

I've even purchased and successfully used universal "key-in-the-box" type bypasses from the local auto parts store in the past.
