2004 Toyota Corolla, Clutch Bypass, Viper 5806V

Hello All,

I am finishing up a Viper 5806v remote start on my 2004 Corolla and have a question about clutch bypass. The Corolla if I'm not mistaken uses a Normally Open Negative Clutch Circuit. If I am to use the Aux 200mA (-) Starter Output from my remote to trigger the clutch. Should this be done through a relay like suggested in the directed tech tip, and should I be using a diode in front of the (-) output if running a relay as shown. I want to make sure I'm not going to burn up the unit.

If anyone is wondering about the safety portion, the remote is programmed for Manual Transmission operation and I'm asking this question so I can properly bypass the clutch switch with the remote feature while retaining the normal "push clutch to key start safety".

I appreciate your help with this.

You might be mistaken about the 2004 Toyota Corolla's clutch interlock. Did you test the clutch interlock switch with a DMM?

The info I have indicates that it is a N.O. (+) signal. Check the interlock switch connector. If it has two wires with one Red and one Black, verify that the Red wire has +12V* and when the clutch pedal is depressed that +12V gets passed along to the Black wire.

* test should be done with the ignition switch in the ON position

If that is your cars setup, then you can wire up your relay as shown below :
Relay Pin 85 to Viper (-) Starter Output
Relay Pins 86 and 87 to +12V through fuse
Relay Pin 30 to Black wire at clutch interlock switch

To protect the Viper's (-) Starter Output from the relays coil collapse pulse use a 1N4007 diode across the Relay pins 86 and 85 with the diodes band towards Pin 86.

Soldering is fun!
