Hey all, new to the forum here, but reading through, lots of good info 8D
My questions are this:
I got a viper 791VX, but couldn't find an installer around my area, so I decided to take apart my car and install myself (I got a 94 Mazda RX7). There some things about this alarm I am not familiar with, such as the satellite relay w/ a bunch of 8 or 10 gauge wires. I am not going to use the remote start, but I wanted the alarm originally for the keyless entry. I bought an actuator for the doors and had that mounted, but do I need a relay(s)?? Or does the alarm come with it in one of the black boxes?? If I need the relay, do I mount the relays in the door or by the brain?
Please help, I want to install this alarm ASAP so I can drive my car again
The fastest way is to get it done professionally. One hour of your time which you will never get back.
What do you mean you can not find an installer? NO BOX STORE around like BEST BUY....etc. in your area? You will need relays, actuator...
Why don't you take a look here to see if you can find yourself an installer.-------------
Be careful whose advice you buy, but be patient with those who supply it.
Anyone done the install on this Viper unit? Out of the box comes some things I am not familiar with....satellite relay with thick guage wires, a metal switch, and a tiny black box with wires coming out of it (not sure if its the relay for the door lock), but this box has the harness for the door locks that plugs to the brain
I started taking my 94 RX-7 apart a week ago to start my alarm install, I have connected all the wires but I get no input from the alarm. Since part of my engine has been taken apart, I can't completely start my car yet. I got a Viper V791VX and the alarm comes with 10 harnesses.
1. primary harness:
2. secondary harness
3. door lock harness
4. remote start (primary)
5. heavy gauge inline
6. remote start (secondary)
7. led
8. valet
9. antenna
10. shock sensor
here is what I have done so far:
primary harness:
orange - 500mA armed output - DID NOT USE
white - light flash output - connected to RED / black wire (fuse panel)
WHITE/ blue - remote start act input - DID NOT USE
BLACK/ white - 200mA domelight supervision - DID NOT USE
Green - (-)door trigger - connected to Blue/White (-)
Blue - mulitplexed input zone 4 - DID NOT USE
Violet - (+) Door trigger input zone 3 - DID NOT USE
Black - ground to chasis
Brown - siren output - connected to red wire of siren
Red - constant power - connected to BLACK/ green wire
RED / white - (-)200mA channel 2 validity - DID NOT USE
Secondary Harness - DID NOT USE
light blue - second unlock ouput
WHITE/ black - programmable channel 5 output
violet/black - porgrammable channel 4 output
GREEN / WHITE - factory rearm
gray/black - wait to start input
light GREEN/ black - factory disarm
door lock harness: DID NOT USE YET
green - (-)Lock (+) unlock output
blue - (+) Lock (-) unlock output
Remote start primary harness - DID NOT USE
pink/white - 200mA (-) programmable IGN2/ACC2 relay turn on
yellow - IGN input to alarm
pink - (-) 200 mA IGN relay turn on
orange - (-)200mA Acces relay turn on
purple - (-)200mA Starter relay turn on
ORANGE / Black - antiground/ground when armed output
blue - (-) 200mA status output
Heavy gauge inline connector:
purple - (+) output to start (start side) - cut starter cable, connected BLACK/ blue wire closest to firewall
green - onboard start kill (key side) - other side of starter cable, connected BLACK/ blue wire closest to steering wheel
red - high current 12V input - connected to BLACK/ green wire
orange - output to accessory output - connected to blue wire
pink - output to primary IGN - connected to BLACK/ white wire
red - high current 12V input - hooked up to the other red wire on this harness
pink/white - output to second IGN - connected to BLACK / YELLOW wire
RED / white - high current 12V - DEI connected back to red wire/harness
remote start secondary harness: DID NOT USE
blue/white - (-)200mA 2nd status/rear defogger
gray - Hood pinswitch input
brown - brack shutdown wire
violet/white - tach input wire
BLACK/ white - neutral safety switch
valet: plugged into brain
antenna: plugged into brain
LED: plugged into brain
shock sensor: plugged to brain
siren: red - connected to brown wire on main harness; black wire- grounded to chassis
I got some of my information from here:
https://www.the12volt.com/installbay/detail.asp?info=alarm&year=1994&make=Mazda&model=RX-7&ID=18333&type=Alarm
I did not use any resistors/diode, the door lock comes with a relay, but again I have not installed the actuator or ran the wires throgh the door jam. All the fuses are good and connected.
Can anyone see I what have done wrong or am missing?? I do not care for the remote start or even the starter kill, really got it for the keyless entry and since this was a discounted price at bestbuys, I bought the unit....only no install from them.
I would appreciate any help from anyone, I would like to drive my car around again.

how own your mind, control your life.
MECP certified. always use a DMM
Do I need to install this harness for just the alarm to work?? i didn't get the alarm for the R/S, mainly just the keyless entry.
the problem is that when i hook the battery up, the alarm doesn't arm and when I press the transmitter, the transmitter chirps, but doesn't arm or disarm.
Did I wire it up right?
The frist step I am trying to take it getting the alarm to work, then the keyless entry...but can't get the first to work
I have a 94 Mazda RX-7 with a Viper 791VX. I am wondering what harness do I need just to have the alarm work and are the connections I made correct. If so, do I need to program the transmitter or should it work out of the box?
the alarm is not arming and the transmitter only beeps when I press the arm button.
Sounds like that alarm is out of your league. I think you should put the car back together, and find an installer that knows alarms that can install it for you. You're going to create a headache for yourself. I don't think anyone on here can walk you through a complete alarm install.

Rookie of the year that is...
Don't let the smoke out of your equiptment..it doesn't go back in.
99.9% installer in my area won't do the install unless I had bought the alarm from them (warranty issue). the other smaller percentage wants to charge close to the cost of the alarm retail. the last shop quoted me $400 for the install. Now I am kind of stuck
