Hondata S300v2 Water/Meth Fail Safe wire hook up? Transducer
I have the below pictured Transducer with Devils Own/Controller Water/Meth inj kit. It is a 3 wire setup. I have the Transducer T'd inline with the control solenoid after. So pump-transducer-control solenoid.
From my understanding Blk wire is grounded. Grounded to Thermostat. Red wire is ran to the ECU and Blue is not used. I have a Hondata s300v2 does the Red wire go to one of the analog pigtails that the v2 has? I am looking where to put this 1 wire? Also I am curious how do you set this up for fail safe protection is there a certain program such as nitrous to control this in order to back down boost etc? I am not an electrical wiz. But 1 wire short from completion Tuner can handle the rest...
Thanks for the help.

Its a Sensor...all 3 wires need to be ran. The ground should be attached to sensor ground and not a chassis ground. The red wire is likely your 5V reference wire which you should be able to get from the ECU and the Blue wire is signal.

Okay help me out a little more on exactly where I should go with the wires:
I have the Red one going to ECU... figured it would end up going to one of the 5v analog pinouts
Blue Wire from what I was told is not used. However you say it does go somewhere? Where would I put it in?
Black is ground. I have it grounded to thermostat but you say it needs to be grounded to where? Analog inputs also has a ground?
Little more direction

Black ground to Thermostat
Blue to Hondata input

Thanks for the help I think I got it... Red just needs 5v power from ecu where is a good source? and blue goes to one of the analog pigtails of the v2?

So the blue wire goes to any of the Analog inputs below that are 0-5v. Besides the Black. Red wire will go here to as well or where will Red get its power?

Assuming you still do not understand where to get 5V and Sensor ground from, tap into an existing sensor in the engine bay. I suggest pulling 5V from MAP or TPS sensor as well as Sensor ground. The only wire that needs to be ran through firewall to ECU is the blue signal wire.

Hello, I appreciate the info. This is all foreign to me and very hard to find any info on this online...
Yes I have all 8 available on analog pinouts
So Blue Wire will be ran to one of these pinouts on the analog pigtail.
Red wire I have already into car... can't I just tap into one of the wire pinouts there as stated? Like TPS or Map for 5v?
Black wire you say needs to be used with any sensor ground such as TPS and or Map Sensor? Is there another sensor that would work for a ground that easy to get to and or not as important... liery of splicing into something critical as map or tps. But if fine then it will work.
There is also a 2 Blk ground wires that is on the analog pigtail. I believe it can be used as a sensor ground? I could use this with the Blk wire?
Per Hondata:
Warning:
The ground pins on the analog input connector are connected directly to the ECU ground plane. The ECU will be damaged if power is applied to these pins.

If there are 2 grounds on your Analog input plane, Check that they are sensor ground before connecting. If you do not want to tap into MAP or TPS, there is always Coolant temp and Air temp sensors that will house a Sensor Ground. Your 5V power will have to be taken from a MAP, TPS or back at the ECU should you be able to locate and trace the 5V back that far.

Re: Hondata S300v2 Water/Meth Fail Safe wire hook up? Transducer
I talked to someone... the 8 analog inputs are only for monitoring...
B5 ac, B8 psp, D4 scs, D2 Brake sw and D6 vtp... are all usuable inputs for secondary map switching...
---------------------------------------------------
Red or Blue wire can be used either or. Not both. I will be using Red into D4 Service Connector for input of secondary map.
Blk is sensor ground as stated 3 way tap into A24 pinout
