Dynotune switch commander, purge and 360 heater help RELAY related Lets start off. I HATE relays. For whatever reason I can NEVER get them to work properly??? For my 360 heater I had a heavy duty switch on the bracket and fed the power straight to it and just flipped it, because I could NOT get the relay to work. Well now I am having the same issues with my purge. I guess if it is not laid out to me I am lost. So I am going to get 2 new relays and harnesses today and start all over. Here is the control panel or simple switches I am using: http://www.dynotunenitrous.com/store...H%20CENTER.pdf
So first challange: wire in purge. I had it connected to the momentary button prior to the panl and it functioned fine.
Dynotune Nitrous control panel White wire to PIN86 of relay, PIN85 to ground, and I assumed PIN30 to 12+ and 87 would go to the wire from the mom. switch that activated the purge??? That did not work so here is what I need
Pin86- Control center White wire
Pin85- common ground
Pin30-middle or side? does it matter?
Pin87-?
Once thats fixxed I now have a 360 bottle heater wiring issue. Same think I am retarded and can't get a relay to work. I have not even tried with the switch. Right now I am what I feel set up for success. I have 3 wires at my bottle heater now one is 12+, one ground, and the brown wire from the switch. Where do they all go on the relay. Again I will assume the 12+ will go to the relay, the ground will be split and go to the relay and bottle heater, while the brown goes to the relay???
Pin86- Control center brown wire
Pin85- common ground
Pin30-middle or side? does it matter?
Pin87-?

ok Teddy... let's back up here a little. First, electronics 101
There are two parts to a relay. Part 1 is the activating coil. It's represented by the coil looking lines in the pic below. That is the LOW CURRENT activation side. Switched 12v on one side, ground on the other. It doesn't matter which is 85 and which is 86 as long as it's 12v/gnd.
The other part of the relay is just contacts. That's for the HIGH CURRENT. It's like taking a wire, cutting it, and taping the two ends together. It just completes a connection.
Ok, so on to your issues.
1. you don't really need a relay on a purge. A decent switch will handle the momentary contact.
2. The "white" wire you're talking about from the nitrous control is 12v when activated. That will go on either 85 or 86 and ground the other pin.
3. The third wire on the bottle heater is for activation. That wire will go to the pressure switch, and from there go to pin 85 (or 86) of a relay.
That relay pin 30 will go directly to the battery (with a heavy guage wire) and pin 87 to the heater.
I've attached an 860 picture below and added pin numbers to the wires. I don't know why they don't do it this way. It would make life so much easier.

Todd- You are the man my friend. Most of that really makes sense I guess I need to just take it all in. With the purge when I go directly to the switch I get nothing, but my button worrked fine. Oh well. I will look into that. Now do I HAVE to use the pressure switch for the heater? I want to be able to just manually turn it off and on???

it would be a REALLY good idea to use the pressure switch. The 860 is a very good heater and can easily "over heat" your bottle.. ie. too much pressure. Let it do what it is designed to do.
As for the purge...

After looking over your diagram for the purge it seems to line up exactly how I had it wired??? I replaced my intake manifold and TB while it has been at the stereo shop so I am going to connect my mom. switch and see if my purge is still working. If not I might have pulled a ground or something?

Teddy, I have a Bottle pressure switch I am not using any more (Vseries gauge the pressure switch is built in the gauge). I get home in Sept and if you want it I will send it to ya. Hit me up with a PM first week in Sept if you want it.
