Honda Fit 2015 AT Viper 4706v with ads alca

I believe that White wire is a slight bit thicker gauge than the Viper H3 wires.  You could run all four +12V input wires to the connection point and then combine 2 of them into one with only 3 inches of a single wire left to the White wire source connection point.  I would not combine all 4 together just after the fuses and then run a single wire any distance to the White source wire.Soldering is fun!

finally did all the wiring.. car didn't explode... so I guess that's a good sign, and it still starts with normal key.. and such. but I cant program the idatalink ... after I choose data mode, it just flashes red... not sure what to do.. I guess. should take a continuity meter to check all the splices.. ? which wires would cause the idatalink to just blind red?

Slow red flash usually means that the alca doesn't see can activity. This means you aren't connected to the correct can wires or the module is not flashed with the correct firmware.

nice, I redid those 2 super thin can wires, and it works now. one thing that I cant seem to get working is re-locking after start... once its started I cant relock with keyfob or with remote fob. I tried setting the option menu1 option 4 to lock only. so that it relocks after start but it still doesn't do it.. only when the engine is off does the lock / unlock buttons work on fobs and r/s fob.. any ideas?

Did you connect the ADS AL CA WHITE/ Black wire on the top 3 Pin plug to the GREEN/ Red wire on the 6 Pin plug?  D2D

won't do that for you.  Also must connect the White and WHITE/ Red wires to the Fit's lock wires.  The only other thingyou need is the Starter input from the Viper to the ADS AL CA but D2D should be handling that for you.

The ADS AL CA can do a re-lock after start if you connect the PURPLE / Black wire to Chassis Ground.  Another case

where D2D doesn't do that for you.

Soldering is fun!

hmm I did all of the above.... doodie. I have a feeling I have another bad splice... I really should test them all.. before I close up the whole dashboard.. shieett.

but if that's the case, why does the lock and unlock button on the viper remote work when the engine is off?

Goes through a different path.  While the engine is off, it uses the ORANGE / Black wire to KeyData.  While the engine is running it uses the direct connections to the lock wires.  It uses the Starter and GWR signals to know the difference.Soldering is fun!
