Connect it to the BLACK/ White if it test out as the starter wire.

I already tried connecting the yellow to the stater wire but im not getting anything. I got it to learn tach but I get no signal when I press the (trunk/key) button twice. My lights wont flash letting me know that the signal was received. Is there a way to test the brain for problems? I

Is there any clicking from the brain?  Do any lights light up on the dash?   Using a DMM check the Ignition, Accessory, and starter outputs of the brain for 12 volts when attempting to remote start.

I get nothing from the brain. Should I get any power output from the yellow starter wire coming from the brain when I attempt to remote start?

Bad ground?.  Hood switch active?  Brake wire active?   Control switch not plugged in and ON?   Poor connections on 12 volts? No voltage getting to brain?   Should have 12 volts output on Purple, Blue, Green and Yellow during remote start.  Time to check each wire carefully.

Are your connections soldered or crimp/scotchlock?

I used my multimeter and checked all of the wires with the car started with the key. No power to the yellow wire but others have power. I can not do a remote start. Ground is good. Tried it with and without the hood switch connected, no luck. voltage is getting to the brain because I pulled the harness from the brain and checked voltage on each wire. Still no luck. Does it matter if the control switch is plugged in or not? I have tried it with and without the switch and no remote start.

You need to check the wires coming out of the brain DURING remote start, not while the car is running. The yellow will have 12 volts ONLY DURING the start sequence. Once started 12 volts is dropped from the starter wire.   Go to the download section of this site, find the Viper 571 install manual. There is a section on finding and testing for the wires you need.

I checked the manual as suggested. I have found all of the wires and they have been connected. I can not remote start for any reason. There is no indication of an output signal from the yellow start wire to the starter. The manual says that this wire must be connect to the vehicle side of the starter cut relay.

Questions:
1. What is the starter cut relay?
2. What would be considered the vehicle side?
3. What would be the opposite of the vehicle side?

1) The relay that cuts the starter, also known as the anti-grind relay.
2) Vehicle side is key side.
3) Starter would be the opposite.
To be honest if you have to ask these questions you shouldn't be doing this on your own.

Here's the simple set-up, wiring by follow the colour:-

Please note:- If they supplied the relay, complete with base and diode if the band on the diode goes to 85, don't worry, just wire the 85 to ignition 1 and the 86 to Ground when Armed, aka GWR orange wire.

Thanks howie ll for your help. It's gladly appreciated. Thanks for the diagrams as well. I have installed many car radios but never a remote start. I have the alarm, flashers, horn, and everything else just not the remote start. I will go now and try again using the relay with 85 on ignition one and 86 to the orange ground when armed wire. I will let you know the outcome.

Remember to look and see where the diode band is.

Does it matter if the 2pin starter control switch is connected or not?

Just join the leads together.

looking at the diagram with the relay connected it shows both yellow and the other half of the starter wire connected. I twisted all 3 wires together, is that the proper way?

Cut starter wire, key side to 87a.
other side + yellow from APS to 30.

Here are my connections. On the relay the stripe points to 85 which is the red wire. The yellow connectors are the two ends of the starter wire.

Sorry I forgot to say that in the 2nd pic it shows 86 to ignition 1 and 85 to GWR I currently have it wired 85 to ignition and 86 to GWR but I was testing both ways and still no luck. Also for the starter on/off switch wires I twisted them together. I tested for +12v on one of the wires and it was live, but once the two were joined together I got 0. Below is what I did. Should they remain as is or do I need to connect them to any other wire? Depending on which wires I get a click from the relay but no remote start response still. My car came with an Automate III alarm which is a DEI product. I removed that because I bought the car with no fobs and it was not hooked up. Could there be another relay I dont know about. I checked under the hood in the fuse box and there is a starter relay there. Could that be some sort of factory starter shut off that gets switched on only when the key is turned to the on position?

On second thoughts don't take it to a pro, they'll take one look at your wiring and say "who did this?"
It's an awful mess.

Thanks for your help!

WOW. A picture IS worth a thousand words.  It seems that this remote starter is not going to work for you. It seems that something is missing from your install that unfortunately we can not see based on your info. 

It should be a easy install...1 Starter, 2 Ignitions, 1 Accessory. .. Along with door locks, Tach, Brake,  ect, ect...

Or maybe you have a dead unit.  Put you car back the way it was.

Get a Viper 5701, Clifford 3.3 or a Python 872. (All the same system that I am more familar with)...All three are remote start/alarm systems.  It might be easer for us to guide/help you to your install.

Also, dump the crimp connectors and get a solder gun and solder your connections.

Thanks smokeman1. I was guessing that there might have been something wrong with the brain why it wouldn't start. Based on all of the threads that I have read here it should have worked with 6 simple wires connected. I am in the process now of getting a new unit probably a Viper. This was my first remote start install but not my first remote start all of my previous cars had Viper alarms and I bought this one to try to install myself this time. I'm sure with a new unit I will be able to install it with no problems.

I'll be brutally honest and forego your previous attempt at sarcasm.
First, this is an EASY car to do but your wiring is atrocious and I'm sure Smokeman agrees.
Second, it might be a PITA to program but A/Vox Prestige products are generally no worse than DEI so don't take the first approach and think "faulty brain".
On products like Compustar, DEI and A/Vox that's pretty rare.
Frankly if you can't make it work with the help and diagrams you've been given don't even attempt another brand, you'll get the same result, i.e. failure.

I was not being sarcastic I simply thanked you for your help. I just expected help and not just criticism of my wiring connections. The yellow connection you see are from a previous install that was already on the car that is not my doing. I didn't bother permanently closing up my leads until I was sure that it worked which is why in the picture you see wires touching but not taped up. What would you suggest I do as far as what see wrong with my install. I tried everything exactly as you stated and it work. I also wired it exactly as the manual states both w/ and w/o the relay and still no remote start. I tested the lead out for the yellow wire when attempting to remote start but I got no readings. There is absolutely no response when I press the remote start. I have attempted to jump the yellow starter wire with red +12v wire and the starter attempts to engage which is the same as jumping the starter. But when I try either of the key fobs the remote start does nothing. No flashing dash lights, no cranking, no voltage. If the brain is not the issue then what is.

How about posting pics of one of your install as an example of how I should model my install after. I came to this forum because I was told it was the best and that there are no @$$hole$ and I would only get HELP!!! If you can not or will not continue to assist me the simply say it and I will not post here again.

But that's the whole point, we have helped, it's an easy install how much more help do you need?
Let's go back to basics.
Check the voltage across your input fuses and the ground.
Check to see if you are getting any outputs from ignition 1 &2 and start when you press the remote.
What worries me is the previously mentioned twisting together of wires, could you have fried the R/S brain?

Is it possible that the remotes are not paired to the remote starter brain?  Bad antenna? Bad cable from brain to antenna?  Do you have a different unit to swap parts? to determine  which component might be faulty?  Just some other ideas.

Lets try this to see if the brain even responds. This is from page 17 of the install manual.

Turn on the ignition---no response

Press and release the valet switch 3 times...should get 1 Chirp and 1 LED Flash

Within 3 seconds, turn the ignition off...should get Short chirp, then one long chirp
