Hi all, I have a question. My boyfriend would like to know...

When he is gonna install the alarm (Viper 791xv) for my car, when it comes to the door locks and the trunk release, does he have to install a relay for them to be work with the alarm system?



One other thing that is off topic but kinda on topic, this one the stereo. He want to install a custome fiberglass system in the trunk, but I dont want to change my headunit. Does the stock stereo have RCA outputs, or does he have to get a line converter to run it off the amp?


Thank you for your help in advance.

1) just install whatever comes with the box. You also need a bypass module to get around the immobilizer function if you want autostart

2) No RCA outs in stock radio

Thank u!!

Moved to ICE & Electrical :wink:

You need something else for the trunk release.

The alarm treats the truck as another door. Or at least that's how my alarm (Clifford Matrix 3.5) treats it. Three clicks and both doors and trunk unlocks. The Clifford Matrix 3.5 and Viper 791VX are pretty much the same alarm.

Now if you want the alarm to pop the trunk up when you unlock it, you will need another piece of equipment. But for ust the basics, the alarm and the bypass module is all you need.

What bypass module? dont i have to just diable the stock alarm by hitting the unlock button on the key and thats it?

I think he is talking about the bypass module for remote start.
You would need something like: http://cgi.ebay.com/ebaymotors/Remote-Car-Start-Universal-Transponder-Bypass-Module_W0QQcmdZViewItemQQcategoryZ33724QQitemZ8016454031QQrdZ1

right but i thought that you only need transpoders on like american cars. Cause i got a tiburon and i installed like 5 of these alarms for buddies of mine and i didnt have to get that transponder b/s.

Now im not completly sure if she needs this, im not 100% familiar with this car. Can someone get me a defite answer if she needs this or not.

You need that for remote start because the tC has a engine immobilizer.

thank you ricexizxgood, im see if i can get one from the dealer, i know someone who may be able to help me out.

Now does anyone know bout the relays for the locks?

I'm not sure which relays you are talking about. But when I got my Viper 791xv installed, I didnt need anything else, just what came in the box.
I just bought a module for remote windows, but thats something else.

Well i know in my car (Tiburon) it need relays for the door locks and the hatch to open.

You have no idea if they installed relays for your door locks. I know that extra thing for the windows to go down, but she doesnt have that/ nor need it. Do you think theres a possibilty you can check to see if you do need em (relays that is)?

Well my reciept only shows one row for labor and doesnt have anything under parts.

iight cool man. at least i know that i have to get that stupid transpoder thing.

you all have been very helpful, and im sure my girlfriend will be happy with her remote start.

i have the factory alarm but want the viper 791xv - do i have to remove the factory alarm before installation of the viper or it will bypass it. thanks. also will the buttons on my key work or i should only use the viper's buttons?

I just installed my Code Alarm remote start system. No extra relays needed for door locks. The trunk is pointless, since it is unlocked w/ the doors anyway.

I did need a relay to bypass the clutch when remote starting - but if yours is auto, there is no need to do so.

As I said earlier, you don't need a relay for the door and trunk.
You do need a bypass for the engine immobolizer if you want remote start. It only costs $40 or so. You will also need to sacrifice your valet key.

I wanted to use my full remote and not the valet key but it wnot' fit. I'll have to ugprade to a keyless one.

you know you realy dont need a relay for the clutch. all you ahve to do is either jump the 2 wires for the clutch switch or have one open. no relay nessacery their.

Its not necessary, but its the "correct" way. Otherwise, you can always start the car w/out pushing the clutch in. It may just save you in cases of a dumb valet guy or something.

yes tru, but i would never let anyone drive my car. I put over 12k into it so far, and that gets me a bit paranoid

When did Code Alarm (audiovox) make a remote start for a manual tranny?
The CORRECT way would be to put in a remote starter for a manual tranny.

I have a bypass that does not use a key.
It also works on any newer toyota.

I'm using the Code Alarm 670 model. Had it on the IS300, now this guy. Works very well. Plus when you get it at cost + free install, you know you have to.

What transponder did you use? On the site, anything for scion TC listed says you need a key.
