06 scion tc with remote start viper 5900

Okay, installed viper 5900 w/ remote start on manual 06 tC

Everything works minus remote start but you can hear the relays clicking when attempting to start from the xcrs but the starter doesnt start.

I have a neutral safety switch via a magnetic switch and the hood pin and everything else is functioning as it should becuase the car attempts to start 3 times.

Car has two igniton, two starter, and one accessory.

The two ignitions are connected as directed with the purple wire and green wire connected on either side of the ignition 1 wire.

I set up a relay to drive the the second ignition wire which I verified is working due to the gauges wont sweep without it connected.

Accessory has juice

The starters are connected with the pink to starter 1 (blue) and pink/white to starter two (yellow). Both have juice.

Car wont start with or without key in ignition which says its not the 556uw bypass malfunctioning.

Tach wire is connected and learned verified by a solid led.

I do not have the RED / white wire connected as i thought is wasn't necessary. I havent attempted to connect it yet

Any ideas?

Forgot to mention that, clutch has a bypass that works.

I attached the red-white wire to another 12v constant source and it atleast cranks now.

But for some reason, it wont learn the tach now, it worked once and the next time it lost signal or something because its what the diagnostics say.

Huh? I think you have it wired wrong. The pinks are ignition wires 1 and 2. The purple and green are the first starter and you need a relay for starter 2. Do you just have it written wrong above?

As for tach, are you at the OBD3 connector under the dash? it should be the wire in the corner by itself....

Well I probably miss typed because i was trying to do it from memory, but i know its right because the car cranked and ran a few times fine but now it loses tach signal. Diagnostic tests comfirm that.

I think the issue is i used the wrong gauge t-tap on the tach wire because that would explain why it was able to learn the tach and perhaps it got bumped and lost signal. I am going to go get the right gauge later tonight and ill update the status.

The wires you wrote and to what color doesn't add up. Green and purple go to the 1st starter wire as a starter kill, green towards key side and purple towards starter side. Pink is ignition 1 and pink/white is ignition 2 or 2nd accessory however you choose to program it.
Then you have orange which is an accessory. Then as noted above you need a separate starter relay. Double check your bypass after you check your primary connections.

The wire I'm test'n isn't doin' what it's supposed to be doin'... I am so glad I printed that tech sheet, with the wrong info.
Do it right the first time... or I might have to fix it for ya

Well either way, I just miss typed but everything is wired correctly because I verified it. I have narrowed the issue to the tachometer wire and I am going to fix it tomorrow.

I was wrestless tonight and decided to get it taken care of.

I couldn't find 18-22 gauge ttaps for the life of me after visiting two autozones, an orielys and a pep-boys.

So i resolved back to the classic cut and solder, and it works like a charm now! I am so happy now.

I agree with tedmond....i started working at a new shop, and am now the only installer.  They sent me a buttload of T-taps, and they are just gonna sit there as i really prefer not to use them at all!!!

...half of the truth can be worse than a lie. <----Roger Russell said that..

do you guys solder and crimp only?

I solder where possible and crimp very seldom. The only crimping done usually is ring terminals for grounding.
