Hondata

Hi,

I have read manual about wiring aftermarket wideband to KPRO, just want to double check. I've been using Innovative Motorsport LC-1 till now, but it gave up after some years and to be honest, wasn't very reliable so I took Hondata's recommandation and got PLX SM-AFR with DM6 gauge combo to replace it.

Planning to wire PLX SM-AFR as follows (PLX to KPRO III):
+12V to switched power (any available source will do?)
GND to one of two Ground wires on KPRO III (as per http://www.hondata.com/help/kmanager/in ... wiring.htm)
Analog output to Analog0 red wire on KPRO III wire
OPTIONAL: Digital out to Digital0 inside ECU on KPRO III three pin digital header (only if Lambda overlay will be possible from Digital0 input)

Thanks for quick check.

The 12v switched power source should be one of the extra connectors in the fuse box that are powered when the ignition is turned on.

I have one 12V wire taken from cigarete lighter which is powered once ingnition is turned on. But if it is better then i can route cable to the fuse box which is under steering wheel. Or did you meant fuse box in engine bay? (I have Civic EP3).

Thanks for info Spunkster.

The under dash fuse box is what I mean. The cigarette lighter is one of the worst locations to use for power.

Ok, I will get +12V from the fuse box, thanks for the info.

OK wideband is wired up and working flawlessly.

For those amateurs like me who are trying to hook it up i recommend to use "add-a-circuit" adaptor to get power from underdash fusebox (spent two hours in "unpossible" positions under the dash, trying to figure out how to get cleanly +12V out of there). After some googling I've found clean solution - "Add-a-circuit" ~$2 solution to this pain.

Here is how it looks like (source: miata.net website):


This gives you idea how it looks like once installed (source: http://www.8thcivic.com website / 8th gen fuse box, not actual EP3 underdash fuse box):


Hope it helps someone and saves time once installing PLX's great device.
