vehicles that require 2 ign , 2 acc

When doing installs on vehicles that require 2 ignition wires AND 2 starter wires (or 2 accessory wires) does everyone always run a relay?

I know most remote start units will provide a wire for a 2nd acc, ign, or starter wire but when vehicles have two of each do you run a relay or do you just split off the ONE wire from the brain to TWO of the acc/starter/ign wires..

Thanks

Always isolate the wires from each other. Use another relay to add 2nd ACC or 2nd IGN to replicate OEM circuits so you don't overload relays and potential cause a short or overload a circuit.

OK. That's what I needed to hear..

Thanks!

Does the 09 Vibe require 2 ignitions and 2 starters?

Also, does it require a bypass? I've seen some sites say yes and some say no...

Thanks

Certainly many installers have jumped two accessory, ignition, or even starter wires together, and powered them from the same output from the remote starter, and gotten away with it without issues.

However, when you do this, you're essentially changing the car from the way it used to be....these wires are jumped together forever, even when the car is off.

It's not a good idea to do that. The car was designed to have the wires separate, the engineers wanted it that way for a reason.

Now, about your Vibe......

It only has two ignitions, one starter, and one accessory. Pretty much any remote starter you buy will have enough outputs for all that.

I don't hook up the accessory because I like the radio to stay off during remote start, but that's up to you.

And I don't remember if the new-for-2009 Vibe has an immobilizer key or not.

Sit in car, with engine off and key removed from ignition. If there's a flashing red light somewhere that reads "SECURITY," you have a (Toyota) immobilizer key there for sure.

09 has the immobilizer, however when i did one last week it didnot have a second starter even though my tech sheet said so

@Howie: What do you mean if more people connected the 2nd ign you would get less requests for rear defroggers?

@Chris: Do you not hook up the accessory wire for any vehicles you do? Is that all the accessory wire controls is the radio? I thought it was used for the blower as well?

Thanks guys!

tbird, Toyotas (Your Vibe is a Corolla station wagon, after all) are a little different. They power up the blower off one of the two main ignition wires.

One other thing about Toyotas is, because of this, the blower stays on even when the key is in the Start position, unlike most other cars where it drops out.

Anyway, most of your (Non Toyota) cars have two (or more) accessory wires: one comes on only in Run, and the other comes on in Acc and Run.

For example, on my Buick that's here, the Run-only wire powers the climate controls, power windows, and I'm sure many other things.

The Acc/Run wire powers the radio, wipers, and I don't know what else.

By leaving the Acc/Run wire disconnected, I can keep the radio off during remote start, and luckily since it also controls the wipers, even if I were to leave the wipers on when I park the car, they won't come back on during remote start.

Not all cars are like this, however.

--Most newer GMs with retained-accessory power, the radio comes on whether you power up the wire or not.

--On some older Fords, the Acc/Run wire also powers the AC compressor. No air conditioning during remote start if you don't power it up.

--On Subarus, the Acc/Run wire controls the heated seats.

--If it's a European car, or some other strange car that I don't feel to comfortable with, I'll power up EVERYTHING just so that I know I'll avoid problems. If you trip a check-engine light on a Volvo, you need a scan tool to clear it....on a Toyota it'll clear just by disconnecting the battery for a few minutes.
