2008 corolla, viper 5301

Thanks for the reply. I got it done. Since the second starter wire was really thin, i thought it will not draw much current and connected it directly to starter output. For the folks who'll come here for help. This is how i connected the wires and it worked. From left to right in a picture Upper row 1. Ignition 2 wire ->H3/6 2. Accessory - black -> H3/3 3. +12v const - yellow thin wire ->H3/2 4. Starter 2 - thin wire -> H3/4 Lower row 5. Starter - Heavy Gauge white wire - H3/4 6. +12v const - heavy gauge white wire - H3/8 7. Ignition wire - gray -> H3/1 H3/5 i connected to H3/8 H3/7 not used. Notes: 1. By default the brain is in Manual Transmission mode. If you car is automatic you have to reprogram it using Valet switch. Check the manual for details. 2. The neutral safety switch should be connected even if it is not closing the contacts. The remote start is showing some strange behavior though. When i lock the car with RS lock, horn honks once and parking lights flash once, valet switch led start to blink. Then if i press unlock on RS horn honks twice, lights flash twice but doors do not open. But if i remote start with control, then during engine run press unlock it will open. What could be the reason? I think i'll post this as a separate topic. Thanks everyone for help. Cheers.

Today i installed viper 5301 on my 2008 corolla (though, someone said it is 2009 model based on electrical diagram) The remote start is showing some strange behavior. When i lock the car with RS lock, horn honks once and parking lights flash once, valet switch led start to blink. Then if i press unlock on RS horn honks twice, lights flash twice but doors do not open. But if i remote start with control, then during engine run press unlock it will open. What could be the reason? Thanks everyone for help. Cheers.

You have the wrong Unlock wire. You have the unlock wire that tests from the Rocker switch on the door panel. That one goes to sleep and will not work after about a minute or so. The rocker switch stops working too(you can test this by rolling down the window and waiting about a minute and stick your hand through the window and press unlock) The proper unlock wire will test while turning the key in the drivers door key cylinder. That wire will always work. You then have to set your system to double pulse unlock. First pulse unlocks drivers door and turns in dome light, second pulse opens the rest of the doors. It will be in the drivers kick panel coming in from the drivers door harness.

Thank you very much. That's exactly how i had tested the wires. I'll correct my mistake soon.

@flobee4 One question: I noticed if the car is remote started, factory remote doesn't unlock the doors. Will this be the case with viper remote control if i change wires as you suggested? I mean can i unlock the door with viper remote control if the car is remotely started? Thanks in advance!

This was easy to check, i remote started the car and opened the door with the key. It worked.

@tedmond: Thanks for the info. Actually it was easy to check, i remote started the car, then opened the door with key. It worked. There is this other question: I'm looking at toyota wiring diagram from directed. It has separate door trigger wires for each door. I need the one which is showing ground when any door is open. Is that the same as dome supervision (-) wire? Thanks for your time.

Would this work for a 05 scion tc as well. i Have everything working in my 5301 viper remote start right down to getting the car to try to start in manual mode but the starter wont crank the engine. i tried doing the flex relays for the 5301 and still didnt work. Just putting two relays in one for each starter seems alot easier. sorry if this is vague...

i guess my next question is do i need to isolate the key side of the starter wire from the starter side when i do this? Any help would be greatly appreciated.. Thanks in advance!
