Tundra 2016, Viper 4806v and FLCAN install

From the Viper instruction: Main Harness/6pin connection of viper: H/1, H/2 - power H/3 - brown - (-) horn honk - somewhere near the steering to the horn switch wire H/4 - WHITE/ brown - flash light isolation wire - pin 87a flash light relay H/5 - white - pin 30 of light flash relay h/6 - orange - ground when armed - not connected H/4 - H/5 - looks like these are normally closed. Where they supposed to be connected? Remote start 8 pin connector: this is supposed to be connected to ignition switch/J9: H3-1 - RED / black - (+) 12V const accessory and starter relays - to battery + (pin 4) H3-2 - pink/black - (+) flex relay input 87A key side ( if required ) of flex relay - not connected H3-3 - pink/white - (+) ignition 2 / flex relay output - to IG1 (pin 1) H3-4 - red - (+) const 12V ignition 1 input - to battery + (pin 5) H3-5 - violet - (+) starter output - to ST2( pin 7) H3-6 - orange - (+) accessory output - to ACC ( pin 2) H3-7 - RED / white - (+) const 12V input ignition 2 and flex relays - to battery + (pin 4) H3-8 - pink - (+) ignition 1 input / output - to IG2 (pin 6) Does it look correct, especially H3-8? I think I don't need to connect anything in auxiliary/shutdown connector. Thanks!

Just did one, a 2016 SR5 with 5.7 L engine. Pretty easy but you must extend some wires to get over, behind the glove box to the TPMS module. The TPMS module is gray with the white 12 Pin connector.

Thanks you! Will do install this Saturday. I'm just thinking about putting "H/5 WHITE PIN 30 of LIGHT FLASH RELAY" to emergency/hazard switch instead

Just finished wiring the thing. FLCAN set to data mode: flashes once. But after I "long press" the button it starting blinking red. The next short press seems to increases the number of blinks. What can be wrong? I bought the FLCAN from ebay and it supposed to be programmed, but I'm not 100% sure. Thanks!

Try this sequence : 1. Disconnect all the FLCAN harnesses except the 4 Pin D2D harness. 2. Disconnect the 4 Pin D2D harness. 3. Press and hold the FLCAN programming button. 4. Plug in the D2D harness. 5. Release the programming button as soon as the LED starts blinking. 6. After a few seconds the FLCAN will start doing a single Green blink. 7. Press and hold the programming button. 8. The LED will go solid Green. Continue holding the button until the LED goes off, then release the button. 9. Reconnect all the remaining FLCAN harnesses. Do not press or bump the programming button. 10. Insert the key into the ignition switch. 11. Turn the key to ON. 12. The LED will go solid Green for 2 seconds and then go OFF. 13. Trun the ignition key to OFF and remove the key. At this point the FLCAN is programmed to the truck. Try a Lock an an Unlock. If you want to run in Tach Mode, do the Tach Learn and then try a remote start.Soldering is fun!

Thank you for the advice! No it opens and closes the door locks, but doesn't start. It clicks relays for 3 times and lights are flashing on the console, but that's it. Tomorrow I'm going to check if I connected H3 correctly by measuring its pins during the the normal acc/on/start. Should I check anything else? Thanks again!

Ignition switch connection measures OK. It wasn't 3 clicks - it was 7 tail light flashing after the remote start command ("manual transmission mode is not configured"). I've programmed it to use automatic transmission mode (menu 3, item 1). Now it is flashed 8 times - "neutral safety wire has no ground or neutral safety switch is off". Switch is in "on position, both terminals measure +12v. Where is this "neutral safety wire" that supposed to be grounded? Or what am I missing? Thanks!

It works now: Auxiliary/Shutdown Harness 24-pin connector 13 BLACK/ WHITE*** (-) NEUTRAL SAFETY /PARKING BRAKE INPUT - should be ON THE GROUND. Vehicle will not start otherwise. One more remark - one doesn't need to remove the glove box to access TPMS connector as many guides recommend. It is quite easy to access by removing the panel underneath the glove box. I'm surprised than Viper is configured by default for a manual transmission, not automatic

Viper is set to Manual Trans Mode as a liability prevention. You must go through the elaborate programming sequence to change it and if you change it and have a Manual Trans, they are not liable for any deaths or damages... Did you try a remote start with the Viper while the truck was in Park with the Parking Brake ON? The FLCAN is supposed to supply the signal for use as the Neutral Safety Input. No harm in going directly to Chassis Ground with an Auto Trans, just interested to see if the FLCAN actually supplied that signal to the Viper.Soldering is fun!
