Installing a remote starter without cutting factory wires?

[yaris08ce]

Is it possible to install a remote starter without cutting any of the factory wires? Are there after-market harnesses available that would plug into the existing connections?

[yaris08ce]

Any help would be appreciated, thanks.

most of the time you do not cut the wiring. you simple strip the covering back and twist wire around and solder and tape the connection. or you can use t-taps but not as reliable as solder.

It's not a high end audio system. Just use t-taps. As long as the taps are closed tightly with pliers, you're good to go. They're not coming off unless someone physically pulls the t-taps open.

when installing a remote starter you MUST cut main ignition and ACC wires..

please do not use T taps, please twist/solder these connections. you will also have to run an independent battery signal to the remote start unit. use a wire heavy enough to support the starting process (8GA recommended)

8GA to send a signal to the starter? are you serious ?

if you don't know how to wire a remote starter you have no idea what i'm talking about

depending on the car but most of the time you do not need to run a new power wire. and the only wire you would cut would be a starter wire if doing anti-grind or starter kill. otherwise you would just strip the jacket off wire and twist solder and tape. do not use any butt connectors or t taps, not reliable over time will corrode or rattle loose.

You don't have to cut any wires - Use tap splices as mentioned. Also, the wire gauge is 16-18 on all of the wires, as our keyswitch is a control circuit, not a power circuit as on many older vehicles. Our keyswitch powers a relay coil, where the relay's contacts then do the high current switching.

The only reason to cut wires would be if you wanted to have the anti-grind feature, which disables the starter when the car has been started by the remote starter. This keeps you remote starting, then getting in the car and accidentally cranking the starter. When I install remote starters on my own cars, I don't bother with the anti-grind feature, but always use it on my wife's car.

so you basically don't have any sort of security built in to the alarms you install? without cutting the ignition wire, all your alarm is is a noise maker.. thief jumps in and drives away because you didn't use an the ignition kill circuit?

My Yaris doesn't have an alarm, but it does have the engine immobilizer, which uses the tansponder key. This is basically the same thing as having an ignition kill switch. The column is still locked without the key as well.

All of these things are easily bypassed by a car theif who knows what he is doing. I don't think that the remote starter makes the car any easier to steal though.

if the install is done right, hopping in and driving away will take at least 3-4 minutes instead of just seconds.. removing enough of the ignition wire and relocating the new "tapping point" deep into the firewall means the thief HAS to pull your dash to steal your car..

Thanks for all the replies. The t-tap connectors look like they'll do the job.

If I had this installed in-store (e.g. Visions), would they cut the wire or use t-tap connectors? I'm guessing it would be up to my preference?

I'm not sure, as I've always installed them myself. I have done them both with the taps and by soldering.

I have never had a tap fail, but I always wrap the taps with electrical tape to make sure that the flap stays down.

i've installed the AST ultrastart 1155tl but are having the following issues:

1. could not locate green wire for PARKING LIGHTS in driver kick
panel, there were 2 greens - 1 (thinner wire) for o.e.m. factory
keyless unlock, while there was no voltage detected in the other
(thicker wire) when activated by remote. also checked grey(according
to yaris forums) wire in kick panel as well but no luck.

2. with factory default settings - pressed unlock or lock in remote 3
times within 3 secs but was unsuccessful with remote start.

3. remote start unit came only with purple (+) start in the 14 pin
power connector which i attached to the green o.e.m. factory keyless
disarm by the driver side kick panel, although this green wire seems
to be (+) and not (-) as indicated in the omega wiring sheet which
said it should work but did not.

I can successfully reset the remote start to factory default setting.
It also seems to be able to tach learn as well. See attached wiring setup
used.



any input would be appreciated.

1. For the parking lights, I used Pin 13 (white wire on the bottom left end) on the headlight dimmer switch connector D4.

2. Probably won't start yet because of the tach learn not being programmed.

Verify the position in the OBDII connector (note that 07 and 09 have a different wire color there, but function is the same):




3. For lock and unlock, here are the correct wires:

i will double check on the tach learn but according to the remote start manual i got the proper confirmation signals, 3 honks. i will check if it is the same location as yours. i got mine from an unused connector somewhat below the left driver comparement(for coins or whatever) w/c is below the cup holder.

do you have a picture of pin 13 - parking lights?

here's what i followed from the remote start itself-

thanks!

Here's the parking light pic:




When you hit the remote start button, what is happening (does it crank, just flash lights, etc)?
