chinese wiring diagram

Hey guys so I got suckered into buying this Chinese "top royal" 2 way car alarm and remote start by inwell model 1386-3506. It's actually pretty cool has decent features and a nice remote. Only problem is THERE IS NO WIRING DIAGRAM. I've been searching all day yesterday and part of today looking for something but I have nothing. If anyone knows about this or could help Id greatly appreciate it. With my multimeter I've already figured the 2 flasher wires, the ignition, run, and starter wires, and I think the tach wire. Everything else is yet to be determined

Just tried googling it myself, a word of very experienced advice.
Please bin it, trying to make the POS work, you'll spend more on tranquilisers than the difference in cost between that and a decent product.
No respectable company will install it.

Yeah I might just end up trying to sell it and buying a viper r/s that does the same thing, but comes with instructions in English

And works

Joking aside, any R/S security that senses tach via the oil pressure switch, don't touch.

Does it really do that? I thought I cut it into the tach wire but then again there is no instructions, as well as the fact that their emails are as follows:
Dear,
Pls contact store you bought from.

Uh what..?

Some of the Oriental/fleabay product yes.
Just about every pro installer has been lumbered with one of these ONCE.
The only time it happened to me I ended up ripping it out, throwing it away and installing a Viper.

Where did you find that info? Oil pressure is an honorable method to determine if an engine is running for engines that have basic oil pressure switches

The combo alarm/rs is obviously going to a knock off of a branded one so if you identify what it's a knock off of then you'll have your installation guide. The wire colors might be a dead match but compare against pin outs and function to verify.

This is true but I'm not even sure what brand to look up

Also could you guys direct me on how to test what pinout does what? I've already tested 2 wires and found them to be the flashers, and 2 other pins have a constant 5 volts no matter what buttons I push, and then nothing else shows any voltage

I'd start by look up all the popular made in china brands. You can also look at install guides for different brands and compare colors, function, and harnesses to what you have - different manufacturers will tend to keep a common wiring pinout and/or color scheme in their product line ups.

Reverse engineering the wire functions is best left to an engineer. The process of reverse engineering from scratch is a long and tedious process. I'd rather phone up inwell in china and as them for a installation/wiring manual.

The nearest is probably Giordion (?) brand.
I spent a surreal hour or so yesterday on the Ali-Baba website, OK boredom and the big (soccer) game hadn't yet started. All the product once you split it up into, GPS, GPS with alarm, security, R/S, R/S with security the different products are all the same.

Directechs he say use 2013 for 2500 model wait 5 and I'll email the Directwire info. Look in Downloads/Manuals section here under 2013 GMC Sierra.

Why not oil pressure?

Why would you want tacho?   Well I assume to sense WHEN the engine has started - and that's a threshold setting - ie, not cranking RPM, but above 400 RPM etc.
Air flaps and spark sensing relays operate before then, but detecting the pulse rate of spark or injectors is fine.
The alternator is no good because although generally the charge light extinguishes after the engine starts, it could extinguish during cranking, or have a lag after starting. Or the alternator may be faulty. The same applies to oil pressure & its switch.

The remote start "MUST" know when the engine has started to disengage the cranking/starter-motor signal. With no oil etc or bad alternator, the R/S could continue cranking long after the engine has started. That's not good - the vehicle can burn when noise-awoken neighbours throw their Molotovs.
Yet again an alternative is cranking stop timers, but that is far from ideal.

That's my simple take on the universe and everything.
Now in my humble non-professional and inexperienced opinion, someone that thinks that oil pressure is ok for engine running sensing or remote starts is playing with fire (literally?).

I've gotten a hold of the diagram and its pretty simple. The tach wire DOES NOT wrap
Around any wires. Instead it looks for ~12v to signal the engines running. I could not find a tach wire in my grand Cherokee since the whole instrument cluster is databus based. I instead just tied the tach into an extra (yes extra for whatever reason) 12v supply out of the remote start brain itself. Start right up and stays running every time. Only thing left to do is the door locks and I'll be done. 6 hour job but hey, it's my first r/s install ever, and it's chinese

I have to wonder who your conversing with, you seem to be talking to yourself.

Your right oil pressure sense is not as good as tach but it's better than voltage sense. It's only for engine running detection not for starter disengagement.

Unless your car is electric, every time you play with your car your playing with fire (internal combustion).

Finally, Catback, you slipped up your bottom line should be "your car you're playing".
And no it wasn't by me, I don't have the knowledge.
Someone else taught me and I edited.
Was it the syntax?

And I've just realised the Sierra post was from another thread.

Huh? And I'm tired, plz excuse my mental absence.

So anyway I spent all day finally hooked everything up correctly as per the instructions and what do you know! doodiety Chinese brain fried itself, and took my drivers side lock actuator and lock/unlock switch down with it.

Sorry to say this but I told you so
And I'm not trying to be silly, sarcastic etc.
Why do you think pros stock with Comp, DEI, Avoxx etc.

I figured why not it was $50 but I've learned my lesson lol

If it's any consolation, you're neither the first nor last.
But we try to discourage people from these POS products, they never listen.
I know you will in future.

I have to wonder what happened to kill your lock actuator and switch.

Sorry for your lost, you live you learn.

It might have sent the wrong signal there's a pos. And neg. pulse out of its own internal "relay" so it probably shorted itself out and doodie the bed
