I am installing CNG to my truck and need some information to finish. I tried my dealer where I bought the truck and they are no help at all.

Which side of the engine is bank one? Drivers or passenger.

Each injector has two wires. There is a brown/white on each injector. The other wire is a different color on each one. I need to determine which wire it the negative wire.

I also need to know which coil wire is positive.

Obviously the techs at my dealer are only parts replacers and don't know too much. They can't even tell me where bank one is.

All help appreciated.

 

Bank 1 is the side with cylinder #1 - which would be the left bank (driver)

You need to get yourself a copy of the FSM for the rest. I've got the wiring diagrams, but trying to do the conversion you are doing without the FSM to look at is not smart.

I'd assume that the dealer tech was trying not to enable someone who hadn't done the research, any tech has access to the wiring diagrams and could answer those questions if they wanted to.

 

I just tried contacting my local dealer requesting they be help me upgrade my 2011 Ram 1500 5.7 Hemi MSD to CNG, but they were no help. Is their a kit? or a list of needed parts?

 

this site has the wiring info you are asking about, it also refers to CNG in some of the sections you ask about, I assume it means Compressed Natural Gas.

They may not be too big of a help because of insurance reasons as well. Almost every company is scared to death these days of a lawsuit in just about any form. And with good reason. Could you imagine the poop storm if you got something wrong, the truck blew up some how and cause property damage or worse, someone's death? They'd quickly be scrubbed across the coals for even the smallest involvement.

It's a cool sounding project, but I can't blame the tech for not wanting to be too helpful. After all, I'm sure he/she wants to keep their job.

 

oYes there is a good kit available and it is really simple to install but as you are finding out the needed information is a little tough to get. The dealers near me just don't have anybody who knows how to do or look up something. They just change parts. Dodge actually has a CNG option but it is only for the 2500.

For those commenting that the techs are protecting their jobs or liability is just wrong. When you pay $40,000 plus for a vehicle and don't have access to the needed information I think they owe to you to give it to you. You can't get the work done by them because they don't have knowledgeable techs in the CNG area.

CNG is not new. It has and is being used around the world for many years and there is a lot of safety built into the system.

There are 3 things that you need to know with the kit I am using. Which side is bank one. Which of the two wires going to the injector is positive. Where is the easiest place to pick up the rpm feed. None of these are rocket science but if you don't have access to the tech information you can't complete the install.

Contact me and I will let you know about the kit I am using.

 

Pedrodog posted a link to all of the information you need. If you are not capable of reading and understanding it then you are not capable of installing the system. This is not a rip on you, but you need to know your limitations before you turn your truck into a fireball.

As for the dealer techs "owing" you anything - nope. You bought a truck that runs on gas. Dodge/Ram doesn't owe you anything but the truck you bought and any work required by the warranty that came with it. You would have the same experience if you went to them looking for advice on how to install a programmer.

 

You must be mistaken that the techs work for Chrysler. They don't. Your 40K didn't include unlimited access to all the dealer tech info AND the time of their employees to stop making a living just to assist you in doing your side project. You can talk all the smack you want, but War Horse is exactly right. NO dealer is going to give you advice on how to blow yourself up. They're going to blow you off. I know I would.

 

Giving advice on how to install a CNG system is NOT the same as providing technical details about the vehicle. Having the tech tell you which bank has cylinder 1 is not a liability. It is a fact. I'm not saying that providing in depth customer education is their duty or that they would spend the time doing it, but the whole "they won't tell you because you'll blow yourself up" thing is a red herring.

It is pretty obvious from some of the comments that some of you don't know anything about CNG. It is perfectly safe. Read up on it, the information is readily available. Not so with what I have asked for unless you have a subscription.

As far as the information asked for at least in my case they just had no clue what I was asking for. Bank One? Which wire is + and which is -. Too bad you can't find knowledgeable techs at a dealership. They could say they don't have time or they don't give out that information. They spent time to research and said they could find no reference to Bank One and one wire was asb control and the other is fuel injection control but could not tell me which was the positive or negative. They did spend some time only to tell me they could not find answers.

As far as not wanting to give out information to convert to CNG, they had no idea why I wanted the information. I simply asked for two pieces of information.

Obviously my truck will not go back to that dealership for service nor will I purchase from them again. I will find a dealership that has a tech that knows what he is doing.

You don't think they owe me a little information then lets hope you don't work there because you have lost a customer. But then again most tech's don't have a clue about customer service. It is much less expensive and time consuming to keep a current customer than it is to acquire a new one. It was the service manager I was dealing with and now he realizes his tech's are not too sharp.
