Remote Start DIY Wiring Guide 2006-2010 Yaris

Actually, all of the wires you will connect to on the Yaris are low current, "control" wires, rather than high current ones, which is what the remote starters are setup to handle, hence their giant size.

So, the issue is seriously mismatched wire sizes for the tap splices. Since the car side is the important side, I actually use the tap splices sized for the car's wires (which are the red ones {24-18 AWG}). When you crimp them onto the small gauge car wire and large gauge remote starter wires, some of the strands of the remote starter wire will get cut off, but what remains will be at least the same gauge as the car wire.

I do use the Scotchlok ones and find them to be better quality than many of the other brands.

Thanks for the info Scott.

So I finally did get the Scotchlok connectors as well as my remote start but I am having some issues getting it going.

This is a Viper 4203v unit (Responder One):

Starter wires -> car wires

Pink Ignition -> Green ignition
Pink/White Secondary ignition -> Pink ignition
Purple Starter -> Black starter
Orange Accessory -> White accessory
Red 12v - 12v on fuse panel (top)
Red 12v - 12v on fuse panel (top)

Black/White Neutral Switch -> to ground
Violet/White Tach wire -> L.Green on OBD2
Brown brake -> Green brake +12
Grey hoodswitch -> not connected

Everything looks like it is connected properly, but it seems the unit will not turn on. I would think if the unit was powering up I would see the red LED come on for at least a second but it does not.

I have checked my connections with a multi-meter and everything looks good.

Is there something I am missing here? I have never installed a remote start before and reading through this thread made me think it was easy, lol.

I don't have the manual for the 4203v, but what you are connected to looks good. Check the install manual for a start-up or configuration process that may have to be done before it will work.

The only thing I can see that I didn't do is the 'tach learning' ... I'm going to try that and see if it works.

OK tried that still nothing.

I am wondering if the hood safety switch needs to be connected to ground for the unit to operate. They don't really explain in the manual except saying it NEEDS to be connected (I've read you don't have to connect it but I guess it's worth a try).

The hood pins ground when the hood is open, so you leave them floating (i.e. not connected) to bypass.

Alright well that eliminates that.

I'm going to verify my ground point ... that's the only other thing I can think of.
