Hello all. First I am very new to this forum, but have been grazing over the site for quite some time now. I am presently installing a car alarm/starter combo in my 2007 Dodge Grand Caravan... I have yet to purchase a bypass module for the van, but there are several shops around town offering them.
Anyway, a few questions... And please forgive what might seem like fragmented or questions that don't make sense. I've scanned the 12volt site but still can't quite make sense of a few things.
1.Which bypass module should I use? And is there a general idea on how to wire up the 2nd starter wire to this module? From what I've been reading you need a negative trigger through a 180 ohm resistor... And I'm supposed to run this through a relay but on the other end of the coil for the SPDT switch, people keep mentioning "Run to ground of BCM when on." Where exactly do I run the second starter wire to in my car alarm?
Here is the installation instructions for my car alarm...
40.Attention for installation
①6 PIN Remote start-up power socket
PIN1: Black and yellow wire – Starter switch-on wire (+12V).
It is connected to ignition lock wire where +12V appears in the “Starter” key position. This signal means engine start-up.
PIN2: Blue wire – IGN 1 wire, output signal +12V.
It is connected to ignition lock wire where +12V appears in the “Ignition ON” key position and does not disappear in the “Starter” position.
PIN3: Orange wire – An output signal +12V ACC – auxiliary equipment.
It is connected to ignition lock wire where +12V appears in the “ACC” and “Ignition ON” key position.
PIN4: Thick red wire – Remote start-up circuit power supply wire (+12V)
It is connected to ignition battery “+” terminal via 30A fuse.
PIN5: Thin red wire – System power supply wire (+12V)
It is connected to ignition battery “+” terminal via 3A fuse.
PIN6: Blue and red wire – IGN 2 wire, output signal +12V.
It is connected to ignition lock wire where +12V appears in the “Ignition ON” key position and disappears in the “Starter” position.
②6 PIN central lock connection socket
System has in-built power relays for central lock control. Wiring for connection of central lock is made in a separate six-pin socket. Please refer to central lock Installation diagram.
PIN1: White wire – Central contact for central lock closing relay
PIN2: Yellow wire – Normally open contact for central lock closing relay
PIN3: Orange wire – Normally closed contact for central lock closing relay
PIN4: Orange and black wire – Normally closed contact for central lock opening relay
PIN5: Yellow and black wire – Normally open contact for central lock opening relay
PIN6: White and black wire – Central contact for central lock opening relay
③8 PIN main socket 1
PIN1: No connection
PIN2: Black wire – System “–”, connect to ground (Ensure reliable contact)
PIN3: Yellow and red wire – Immobilizer bypass output (–250mA), main unit output –250mA pulse while engine running.
PIN4: Green wire – Siren output (3A).
PIN5: Purple wire – Channel 2 output, wire for trunk release(–250mA, 0.8 sec, default setting) or windows closer(–250mA, 25 sec) or potential pulse(–250mA, 30 sec).
This function can be program setting.
PIN6: Thick brown wire – Parking light output wire (7.5A)
PIN7: Yellow wire – Engine-stopper control wire (–250mA output after arming system or –250mA output after disarming system with program setting), connected to engine-stopper relay. Please refer to installation diagram 1.
PIN8: Thick brown wire – Parking light output wire(7.5A)
④8 PIN main socket 2
PIN1: BROWN / white wire – Negative hand-brake trigger input
PIN2: BROWN / black wire – Positive foot-brake trigger input
PIN3: Gray wire – Negative trunk trigger input
PIN4: White wire – Negative door trigger input
PIN5: WHITE/ Red wire – Positive door trigger input
PIN6: Blue/black wire – Control input to start engine from outside device, the negative pulse time is not less than 100ms.
And what about the pin 7 and 8 below? Where do I hook these up to exactly?
PIN7: Blue/red wire – Engine start testing wire 1, input for engine high-voltage, signal to be effective more than 1V .
Please refer to installation diagram 2.
PIN8:Blue/ white wire – Engine start testing wire 2 input for oil pressure sensor, signal to be effective more than 6V .
Please refer to installation diagram 2.
Note: Depending on your need to install testing wire 1 or testing wire 2.
⑤Selection manual or automatic gearshift car
Selection of manual or automatic gearshift car is done using wire loop (refer to installation diagram 2):
Keep wire loop: Manual gearshift car
Cut wire loop: Automatic gearshift car
ATTENTION:
For manual gearshift car, please do not cut the wire loop outside the main unit.
I have both the plain grey Chrysler key and the black one with the lock/unlock symbol.
Thanks in advance for your help guys.
