remote start help101 needed please

here's some follow-up information about using the 2nd starter wire...

[cttitan]

Two things I learned when hooking up my RS.

Is the hood shut when you are trying to start it? Won't start with the hood up or if the hood pin wire is grounded!

When I first tried starting mine my battery had gone dead from having the doors open and lights on for so much time over the few days I was hooking everything up.

I have all of the wiring connections at home so I can't look at everything now but as far as the 2nd starter wire it has nothing to do with cold starting but it is for energizing accessories or ecm stuff IIRC when starting. I'll get my wiring info and get it to you as soon as I get home.

Don't give up. It took me 4 days of laying upside down and cussing to get mine all hooked up but it works great and I love it.

no, the 2nd starter wire provides extra voltage during colder than usual occasions.

the "accessory" wire turns on the accessories. it's +12V when in the accessory position and ignition position but it loses voltage during "starting."

the "ignition" wires (to turn on ECM, BCM, and othe control modules) is +12V when in the ignition position (position after accessory) and it is also +12V during "starting" because it's necessary to have computer functions during this process.

if the 2nd starter wire energizes "ecm stuff"... then why wouldn't you hook it up? doesn't the ecm control the fuel injectors required for starting?

i've installed 20+ remote starters. i use www.the12volt.com for information and anyone with a reputable post count says it's important to hook up the 2nd starter wire (cold start wire).

you may be getting by without implementing the 2nd starter wire but that is not the proper way to do things. if you choose to do it that way, that's fine but don't misinform other members.

some possible consequences of not using the 2nd starter wire is:
- car will not start
- longer crank cycles (diminishes life of starter)

my truck cranks longer on cold days...I got both wires connected...

Think about what you are saying. The starter gets supplied from the battery and doesnt get a "second starter wire" from anything for "cold starts". I never said it wasn't important to hook up to the 2nd start wire, just that it has nothing to do with "cold" starting. As far as reputable post counts go it all comes down to quality and not quantity.

Back to loudtitans problem....

The wiring drawing is attached.

As you can see the 2nd starter wire is for power seats and you don't need to connect to it. But you could connect to the red wire with your pink/white wire for the 2nd ignition/accesory circuit. The relay setup is not needed.

Here is how I would hook it up.

Pink to Black/Red for Ignition
Purple to Brown for Starter
Orange to Purple for Acc
Red (2) to battery for +12volt in
Pink/White to Red for 2nd ignition

A +/- shutdown probably means it got a shutdown from the hood pin or brake pedal +/- signal.

Have you looked at the wiring diagrams???? The ONLY thing this "2nd starter wire" feeds is the automatic seats. It DOES NOT power "ECM stuff", or any other control module other than the one in the seat. If the wire isn't needed, it isn't needed. The "2nd start wire" may be used in other vehicles for starting purposes. It isn't here. The "proper" way to do things is to connect wires that need connecting. If I had the LE with auto-seats, I'd solder it in.

Provides extra voltage??? I repair and maintain the control computers for a nuclear plant. If I walked into the shop and made that statement I'd be pilloried by my coworkers.

12volt.com has a lot of info. I found a lot of good information, especially for fibreglassing. But a "reputable number of posts" does not make something true. The problem with that forum is you have to wade thru the crap to find the diamonds of information.

An auto technician worth his 75 bucks an hour would know the wires he's connecting to before attempting an install. Otherwise, he's just a hack.

Still don't believe me? Check out "PG-15" in the 2005 Nissan Titan Service Manual. You DO have the service manual, don't you?

If anyone wants this page, PM me and I'll be happy to help.

i stand corrected. everything in my post that i "quoted" was something another member has said... not something that i made up.

i have always read that it is important to wire up the 2nd starter because of cold start issues. apparently it's different in some vehicles like the Titan.

i refer to DEI wiring diagrams during my installs and without going to the service manual of each vehicle, i feel that they list all the wires for a reason on that wiring diagram. i recheck the colors with a multimeter and i install. i've done many of these installs this way and i've never had a problem and it always takes me less than a day even when it's a vehicle i've never done before.

i'm sorry... i didn't mean extra voltage... but extra current capacity.

with regards to posts, of course it comes down to quality... that's a given. reputable post count with quality information. after a lot of time on that site, you see names that post good information over and over again just like on this site.

The issue for loudtitan, given his model is an XE, is that adding the second start wire will not provide him any benefit, and will only complicate the install. Since he has some troubleshooting to do, this will only add to his headaches.

As most know, the starter draws a lot of current while turning over. Typically, a solenoid (relay) is used to handle the high current. Adding an extra wire would provide no benefit to the starter.

The Driver's seat control unit uses the second start wire to temporarily inhibit seat operation when the key is turned to start. I'm guessing DEI has omitted the info in whatever diagrams they provide.

[loudtitan]

believe it or not my truck starts by remote control now. added a relay and it started right up. as i used to install alarms and stereos when i was in high school (15 years ago) this remote start kicked my a$$. my brain doesn't function well reading instructions, after looking at the pics and diagrams from everyone that helped it finally fell into place. if you attempt to do this yourself take the dash completely apart it is alot easier to get to wires with a soldering iron. thank you everyone that contributed to this project and one last piece of advice, wait til you get done before you drink the beer it doesn't help during the install at all. you can't throw pliers as far after you've been drinking.

I knew you could do it!

Now come to New Jersey and do mine. Please?!

not even if you paid my titan off and ran around the truck in speedos while i did the install.

[cttitan]

That's great news. Glad to hear you were able to get it working.

Enjoy.

[Nestor]

Congrats, Loudtitan!

[f00dstamps]

congratulations. that's not too bad for a 1st time! how exactly did you get it to work? how did you use the relay?

After all the words of encouragement, you treat me that way?
You're a pro now, I thought you would get it done way faster than I can.
You'll never see this man in a Speedo.
