@Xulfiqar.

When It See +12v...It Will Consider It In Neutral I Guess.....!! So Mating It With STA Will Simply Give It +12v On Crank And Then No Signal.....!!

Will Make It Work Fine And I Guess Its How Factory wire It Also

They Just Put Switch In Between Both STA And NSW And Connect Starter Relay And STA With That Switch.........!!!

Connected STA Pin. Pin was missing and it took a lot of time to figure out how to put other one. After learning the trick, it worked like a charm!
Next biggi is the Fuel pump connection.
I want to ask you guys, that will this relay be used as a Circuit Open relay? couldnt find exact labeled 'Circuit Relay' in local market

^^ This One Is Different I Guess

simply Use 2 Normal Relays To Make It Work

With Toyota Fuel Pump Relay (Circuit Opening)

Using 2 Normal 4 Point Relays...

With CNG installed, the IG+ , which is live after the car is started, can be replaced by the wire from CNG Switch (12v) for petrol?
or
another relay should be installed between point (1) and fuel pump getting live from CNG switch?

Tested the relay i bought and it didnot have load(resistance) on point 3-6, so i got another one, which i will test and if it will not work, i'll simply go for two

thats not a gud approach bcz Fuel Pump requires high current & CNG SW Transistor provides limited current + more the wire length more will be the line losses, better to drive it via relay.

Yup add another relay in between point (1) & fuel pump to cut the fuel pump

Open Google. On your phone. Type Toyota Circuit opening relay. Save pictures show them. Both front and back.

I saw one guy had 10 or 12 of these. Go to ahata Mithu khan and goto basement on your right there is a shop, First shop I always bought from him.

Add Another relay As That Point Out Of Switch Was Only For Operating Small Load....Hardly 1A...

On Other Hand..The Fuel Pump Itself Draws Around 8-9Amp So That Should Burn Your Switch

Use Relay And Put Good Guage Wire To Connect Fuel Pump .....!

SER_GTR (SER_GTR) 2013-12-02 06:42:49 +0500 #114

The Relay Shows Simply Circuit Open On It Or Fuel Pump Relay....!!

Try With Body Parts SHop As Its Located Mostly Inside Cabin

I always took a picture print of the relay or show them in phone. They quickly understand and bring it :p..

ecu_designer (ecu_designer) 2013-12-02 07:40:55 +0500 #117

Bro G-9 Karachi Company is not a right place for automotive parts go to Pindi Sadar "Mithu khan ka ahatah" if u cant then simply use 2-Relays as mentioned by @ser_gtr

SER_GTR (SER_GTR) 2013-12-02 09:37:28 +0500 #118

Karachi COMPANY is a name given to a market/area which was designed by a company from Karachi.

today while driving i felt like head lights gone a bit low few times. i switched on the heater and one time it felt that it becomes faster, then for a fraction of a second car's battery light blinked, after that drive few miles and nothing happened.

Got the Circuit Open Relay by the way, from same Karachi company! was there to return but fortunately got it !
