Delayed relay output?

I thought the 611T only would time up to 100 sec. and was rated for 5A?

So, like this?

I used Paint Shop Pro  

I've got a bunch of Bosch relays here already so figured I'd just use two of them, actually the only thing I need is the transistor (well, I'll have to put a few resistors in series to get 5.6M thou!)

I figured I could hook the ground to the 'ground out while running' on the RS so it would only works while under remote start...

Daymm, that Mouser.com site has alot of stuff! The more I look at it the less I feel I ever knew about this things! lol...

Instead of building a timer why don't you just use the timer of the remote start?  Assuming the remote start only stays activated for 12 mintues (estimate) that would be a perfect timer.  You could cut down your parts list tremendiously.

Use the (-) channel to activate the relay on the right.  This relay will get its positive from the accessory out of the RS (so it will only latch when the car is remote started).  The relay on the right will provide a latch to the relay on the left.

Since you are using the accessory output you will need to diode isolate the accessory circuit of the vehicle, this is the only 'snag'.  If you have access to the 3A diodes wire four of them in parallel. 

So, you remote start the car.  Both relays have 12VDC on one side of the coil.  You hit the AUX button and both relays pull in.  They will stay energized for as long as the car is remote started.  When you end the remote start session you can manually turn the defroster on.
