2011 Toyota Tacoma and Viper 5706v

Connect both starter wires, use the Violet (purple) and green at H3 for BLACK/ white. Use H2 /21 violet / YELLOW to second starter via a relay as follows:- Violet / YELLOW to 85, 12V+ constant fused at 30 amps to 87 and 86, 30 to GREEN/ black. Diode (1N4004) between 85 and 86, band to 86, stops relay shutdown spike damaging the 5706. To the best of my knowledge Toyota have never used a NEG output on an Ignition wire except on PTS vehicles. Pay careful attention to where the plug fits into the control centre (antenna).

Thank you for the reply. Yes, I understood how to run the relay to appropriate wires. What I have a problem with right now is discrepencies on wiring diagram. As I mentioned previous post, the wiring diagram from modifilif.e. has [quote] Vehicle Ignition Wire (+): Blue / YELLOW Vehicle Second Ignition Wire (+): BLACK/ Red Automobile Engine Starter Wire (+): BLACK/ White Automobile Second Engine Starter Wire (-): GREEN/ Black [/quote] Where some other sites have the wiring as : [quote] Starter GREEN/ black      + Second Starter      BLACK/ white      +         Ignition      BLACK/ red      +      Second Ignition      blue / YELLOW      + [/quote] Which one is correct? I followed the post from tacomaworld in my previous post and someone in that forum said that his truck all messed up when he followed the 2nd diagram. He didn't post anything else after that so I couldn't verify. One of the post here on the12volts for the installation of the 2010 Tacoma and they used the 2nd diagram. Please help, I don't want to mess up my truck by switch up the starter/2nd starter or ignition/2nd ignition,

Obvious answer, TEST

How? Ignitions wires from both diagram listed + polarity .

Kreg might be more diplomatic but to be blunt if you have to question my last post should you even be attempting this install? Now I,ve vented a bit, all the guides should be taken as guides NOT instructions. You must test and verify everything.

Please pardon my ignorance, but how do figure out/ test for First diagram: Vehicle Ignition Wire (+): Blue / YELLOW Second diagram: Second Ignition      blue / YELLOW      + They're both (+), same color of wires, one diagram call out "Ignition wire" and one diagram call out " Second Ignition" ? About the comment that should I not even attempt to install this? My reply is sir: How do one learn to drive? I have posted questions here with backup references from my research. I don't know much about this stuff that's why i have all these questions so I can learn by doing.........

Kreg has already explained how to test this using a meter, please read that post again. Remember this isn't "painting by numbers", and never assume, you have to test. No one here is going to take you by the hand you have to show some initiative.

multimeter: black to ground, red to "testing" wire. Wire should show 12v at the ignition position, and during start. ignition and second ignition is still an ignition. for example Person 1 and Person 2. Still, they are infact still people. Toyota is known for 2x starters and 2x ignitions. Do test all your wires. 12 Volts     WHITE/ red (30A)     +     ignition switch, white 8 pin plug, pin 5 Second 12 Volts     WHITE/ blue (50A)     +     ignition switch, white 8 pin plug, pin 4 Starter     GREEN/ black     +     ignition switch, white 8 pin plug, pin 7 Second Starter     BLACK/ white     +     ignition switch, white 8 pin plug, pin 3 Ignition     BLACK/ red     +     ignition switch, white 8 pin plug, pin 6 Second Ignition     blue / YELLOW     +     ignition switch, white 8 pin plug, pin 1      Accessory     WHITE/ green     +     ignition switch, white 8 pin plug, pin 2 Ted

Ok. Let me try one more time. I know how to test for wires thanks to Kreg, and numerous youtube videos. Here is the problem I'm facing: One website listed: Ignition wire : Blue / YELLOW (+) One website listed: Ignition Wire : BLACK/ Red (+) Similar with Starter and Second Starter. They have the names of those wires swapped. Now, when I did the test for the Blue / YELLOW and BLACK/ Red wires. I get for both : Off : 0 volts Acc: 12 volts Crank: 12 volts Running: 12 volts. So which one is Ignition wire so I can hook it up correctly? Thanks

OK, forget everything you've read up so far and lose the meter, both irrelevant. We're going to do this old school. Get yourself a decent bulb tester, Snap-On, Mac, Craftsman. Place the clip to ground and probe the ignition switch loom. You will get the following as you turn the key from off to start. Two will be at 12 volts all the time note the colours. Power sources. One will be live only on ACC, ignition and engine run NOT crank. Note the colour. ACC Two will be live on ignition, crank and engine run. Note the colours. Ignition 1 and 2. Two will be live only on crank. Note the colours. Starter 1 and 2. That's it and to be honest that's how I STILL do it. Much, much quicker but reserved for pros because we (should) know when to only use a meter.
