hi i was going to purchase a Viper 791 security system with auto start and power locks. i have a 97 honda accord with a manualy transmission. i was wondering if it was possible to some how install the auto start on this car by bypassing the clutch. If anyone knows how to install this and can tell me how to by pass the clutch please let me know how. if anyone has this security system please let me know and tell me how it is and what you would recomend thanks alot.

there's two easy ways on most honda's.

first one is to send Ground (-) out when running from the RS ( prolly called 3rd IGN -, or something like that on your DEI) to one of the wires at the pedal. there will be two wires at the pedal, one is ground, the other is only ground when the pedal is in <--- use this wire.

the second way is direct feed. find the clutch wire that sends +12 v to the solenoid. it is usually in the drivers kick some where. there will be two fat wires there, one come from the key to the relay, the other from the relay to the solenoid <--- connect the starter wire out put to this wire.

if you need more, I'll post one of the instruction manuals I wrote for work.

good luck.

If you could post those manuals that would be very tight...

just be careful if you install the remote start, because you will be responsable for all damages you cause by leaving it in gear. dont think your insurance company will pick up the tab for any damages that your car causes because of the remote start.

no problem.

Here's my clutch bypass essay:

As I said up there ^, on honda's you get your choice of direct feed at the relay ( connect the RS starter output wire directly to the wire off the relay, that spins the starter motor) or negative trigger. with negative trigger, your are "only pressing the pedal", so you still need to connect the RS starter wire ( to the starter wire you find at the Ignition primaries), in order to crank the starter motor over. again, do this only with an RS made for manual trannys.

Clutch Bypass
In order to remote start a manual transmission vehicle, the clutch switch must be bypassed. Clutch safety switch circuits can take many forms. Listed below are the most common ones. When testing to determine the type of clutch circuit, it is recommended to use a computer safe logic probe. Some vehicles may also have a separate or combined switch on the clutch pedal for cruise control. Usually a cruise control switch reacts the moment you touch the pedal, where as a clutch switch reacts only when the pedal is near the floor. Once the circuit type has been determined, you must recreate what happens electrically at the switch, with the remote start module, to bypass the clutch during remote starts. Relays are often used to accomplish this. You can use the Ground Out When Running (G.O.) wire as the negative trigger on your clutch bypass relays, as it is only active during remote starts. NEVER permanently bypass a clutch switch. Do not attempt this if you are unfamiliar with the use of relays, and diode isolation.

Before any Hot Wiring attempts:

Test and record the way each wire tests in the following positions:


With out the pedal pressed:
test the wire with the Ignition OFF
test the wire with the Ignition ON
test the wire with the Key in the start position

With the pedal pressed:
test the wire with the Ignition OFF
test the wire with the Ignition ON
test the wire with the Key in the start position

With this information for every wire at the switch, determining what type of clutch switching system you have will be easy.


Direct Feed:
The simplest type of system to test and bypass is the “Direct Feed” system. This circuit simply interrupts the +12v signal starter wire from the ignition switch to the starter solenoid. There are 2 wires in this circuit, the “key side” wire which goes from the clutch pedal to the Ignition switch, and the “solenoid side” which goes from the clutch switch to the starter motor. When the key is turned to the start position without pressing the pedal, you will test 12v only on one of the wires at the clutch switch, this is the key side. When the pedal is pressed down, and the key is in the crank position, the other wire will also read 12 volts; this is the solenoid side wire. To confirm you have a direct feed clutch switch, hot wire the “solenoid side” wire with a fused +12 volts and the starter motor will crank. Connect the starter output from the remote starter to solenoid side wire.
Note: In the next two systems a Relay in the vehicle interrupts the start wire between the Ignition switch and the starter motor. With the key in the start position, and the clutch pedal pressed, the relay energizes and allows the start signal to reach the starter motor. In these systems a wires from the clutch triggers the relay, when the pedal is pressed. There will be another wire at the clutch switch that supplies the signal to the trigger wire (either positive or negative, depending on the system)


Negative:
In a Negative system, when the clutch is pressed; a negative signal is sent to the relay, the relay energizes, when the Key is turned to the start position the 12volts from the start wire is allowed to pass through the relay and to starter motor. One of the wires at the clutch will test as negative, this is the supply wire. The relay's negative trigger wire will only show negative when the pedal is pressed (some vehicle's also require the Ignition system to be powered). To confirm you have a Negative system, hot wire the negative trigger wire by jumping it to a ground source with your fused test jumper. You should now be able to turn the key to the start position and engage the start motor without pressing in the clutch pedal. If there is nothing else connected to the Ground Out When Running (G.O.) wire from the remote start module, the G.O. wire should be strong enough to trigger the vehicle's clutch relay. If there are other devices or modules connected to the G.O. Wire, a relay (and diodes) may have to be added to strengthen the negative current going to the clutch bypass.


Positive:
Very similar to the negative system, except that the vehicle's clutch relay is trigger by 12 volts, instead of a negative signal. In a Positive system, when the clutch is pressed; a positive (12 volts) signal is sent to the relay, the relay energizes, when the Key is turned to the start position the 12 volts from the start wire is allowed to pass through the relay and to starter motor. One of the wires at the clutch will test as 12 volts, this is the supply wire. The relay's positive trigger wire will only show positive when the pedal is pressed (some vehicle's also require the Ignition system to be powered). To confirm you have Positive system, hot wire the positive trigger wire by jumping it to a 12 volt source with your fused test jumper. You should now be able to turn the key to the start position and engage the start motor, without pressing in the clutch pedal. A relay is needed to send 12 volts to the trigger wire from the start module during start attempts.


Normally Closed ( N/C ):
Note: There are different types of this system used by various vehicle manufacturers; the following is used to illustrate how these systems work in general.
A Relay is also used in these types of systems to interrupt the starter wire. In the previous two examples, the clutch was bypassed by engaging the clutch relay; with this system you bypass the clutch by preventing the clutch relay from engaging. When the Ignition Key is turned to the start position the relay energizes and interrupts the start wire, when the pedal is not pressed. When the Ignition key is turned to the start position, and the pedal is pressed, the relay does not energize, and the start signal reaches the starter motor.
In a N/C system the supply wire is connected to the relay's trigger wire at rest (pedal not pressed). When the pedal is pressed, the connection is broken between the supply wire and the relay's trigger wire (this disengages the relay). To verify that you have a N/C system, disconnect the clutch switch and the vehicle should start without the clutch pedal being pressed. When you test the trigger wire with your logic probe, the trigger wire will test as 12 volts or negative when the pedal is not pressed, it should read as an open circuit ( or Float) when the pedal is pressed, please note: your probe may also show feed back from the other end of the circuit. The Polarity of the Trigger wire does not matter in this system, since all you need to do in order to bypass it is to use a relay to interrupt it during remote starts.
